When it comes to choosing an adhesive or sealant for your specific application, the task can seem overwhelming with so many different products on the market today. Although the two terms are sometimes used interchangeably, there are some critical differences that should be noted before making your selection. In this article, we will discuss the specific properties of both and their unique applications to confidently equip you with the information you need to grant your “seal of approval” and stick with it!
Sealants are designed to eliminate gaps between surfaces and prevent things like dust or dirt from getting in. Due to the tight molecular structure of sealants, they are particularly effective in keeping moisture in or out of the components in which they are used. With a paste-like consistency that allows filling of gaps between substrates and minimal shrinkage after application, sealants contain fast-drying resins and epoxies that form a slick finish. Despite not having great strength, they provide thermal and acoustical insulation and may serve as fire barriers. Also used for smoothing or filleting, sealants are generally malleable and have high elongation when compared to adhesives. Commonly applied with a caulking gun or specialized applicator, multi-component sealants are composed of a base and applicator component. The activator is typically added to the base component and mixed for a set period of time before application. Single-component sealants, on the other hand, are commonly packaged in a cartridge and require no mixing or special equipment for application.
Sealant Types and Usage
Sealants are often used in joints between individual stone or metal panels, between stone panels and flashing, at expansion and coping joints in masonry, around window and door openings, and in joints at horizontal surfaces. The most common types of joint sealants include acrylics, silicones, polyurethanes, polysulfides, latex and butyls.
Adhesives are designed to permanently bind one surface to another, serving as a sort of “industrial glue” for a variety of applications. Although adhesives are more rigid, durable and powerful than sealants, they can be nearly impossible to remove. Generally comprised of more complex structures engineered to grip and bind on a cellular level, they require a better adhesion to surfaces in order for them to hold properly. Consequently, the surface must be thoroughly cleaned and/or specially treated to ensure a secure and long-lasting bond. Available in spray and paint formulas, adhesives will not always dry properly when used on an exterior surface.
Adhesive Types and Usage
Metal antiques, not unlike people, tend to get a bit rusty with age. Aside from the aesthetic repercussions of the aging process, rust, when left unchecked, will eventually eat away at metal. Such degradation results in an overall loss of value and quality, eventually destroying the item beyond repair. Rust, simply put, is the direct outcome of the mixing of iron, oxygen and water from the air. When iron and oxygen combine, the iron loses electrons to oxygen atoms. This transaction is referred to as oxidation and results in the production of a chemical reaction that forms Fe203 Iron Oxide, more commonly known as rust. Consequently, antiques that are left outside or exposed to high humidity levels and/or heavy water exposure are at particular risk for the formation of this by-product. Until recently, rust removal necessitated the use of harsh chemical solvents that, while effective at removing rust, often compromised the integrity of paint on precious metals, as well as the health and safety of its users. However, thanks to the innovative advancements of companies such as Archoil, aging gracefully has never been so easy or so effective. Archoil 5100 works through a process called chelation in which a large synthetic molecule forms a strong bond with metal oxides (rust), but not with the host metal, pulling rust from both ferrous and non-ferrous metals without harming paint. Fast-acting, non-acidic and non-toxic, Archoil Rust Remover Concentrate can operate in temperatures spanning from 65-160 degrees Fahrenheit, but it is worthwhile noting that increases in temperature also decrease the amount of time needed to remove oxidation, especially on heavily rusted metals. To use, simply dilute 1 part AR5100 in 16 parts water and immerse item in the diluted solution, allowing it to soak until all of the oxidation has been removed. Unlike other products on the market today, AR5100 will not form a patina or convert the rust to a new material. With Archoil 5100 Rust Remover Concentrate making old things look like new has never been easier!
Animal identification serves as the foundation for maintaining accurate production records of herds and flocks, tracking animal growth, managing treatment records and movement, as well as providing proof of ownership to individuals. Perhaps even more valuable, though, is the critical role a successful identification system plays in global trade, endangered species tracking, emergency management, food safety and disease eradication. In the case of a disease outbreak, the ability to identify farm animals provides farmers and veterinarians with a means to track those animals that are sold or transported to other farms or processing facilities. Such traceability plays a crucial part in helping secure the safety of our food supply, as it provides a way to determine each animal’s unique path and helps pinpoint livestock that may have been exposed to a disease through direct contact with an infected animal. Because some animal diseases also have human health implications, it is essential to properly identify animals to help prevent and eradicate diseases. Throughout this article we will take a look at both permanent and temporary methods of livestock identification, providing you with the information necessary to help educate and guide your decisions when it comes to the long-term care of your livestock and you.
Permanent Forms of Identification:
Temporary Forms of Identification:
Although there is not a “one-size-fits-all” solution for every situation, the importance of selecting an identification method that suits the needs and expected uses of your animal can not be disputed. When used in the correct manner, and under the appropriate conditions, each method will go a long way in supporting the rapid traceability of animals in an emergency response situation while also preserving product integrity and allowing producers to maintain accurate management records.
The use of nanotechnology in today’s manufacturing realm has resulted in the production of improved materials and new products that are better built, longer lasting, cleaner, safer and smarter products for the home and a multitude of industries. Although many manufacturers boast the the utilization of this technology in the research and development of their products, few purchasers understand the science and application of such innovation. Nanotechnology involves the study and manipulation of extremely small particles of matter, namely individual atoms and molecules that cannot be seen with the naked eye or even with the most common microscopes. How different atoms are arranged in something can affect the various properties of that item such as it’s strength, texture, durability or odor. Scientists who study nanotechnology alter the structures of materials at extremely small scales to achieve specific and new emergent properties. This is accomplished by putting atoms together in ways we have never done before, creating materials that are stronger, lighter, more durable, water-repellent, anti-reflective, self-cleaning, ultraviolet or infrared-resistant, anti-fog, antimicrobial, scratch-resistant or electrically conducive, among other things. The challenge with such an endeavor is that atoms are incredibly small and consequently, difficult to work with. In fact, the radius of a typical atom is one tenth of a billionth of a meter. To put this in perspective, a string of atoms one meter long would contain an atom for every person in the world. Fortunately, over the past few decades, scientists and engineers have become increasingly skilled at engineering materials down to individual atoms or groups of atoms. Many everyday commercial products that are now on the market rely on nanoscale materials and processes including fabric, sporting goods, automobile parts, luggage, batteries, food, electronics, medicine and fuel and it is estimated that the global nanotechnology market will reach $90.5 billion by 2021.
The study and utilization of nanotechnology is paving the way for new innovations that may benefit society in ways that we have not even begun to imagine. To date, nanotechnology is already broadening the medical tools, knowledge and therapies currently available to doctors, which may lead to the earlier detection and treatment of cancer and other medical conditions. Nanotechnology researchers are currently working on a number of different therapeutics where a nanoparticle can encapsulate or otherwise help to deliver medication directly to cancer cells and minimize the risk of damage to healthy tissue, as well exploring ways that nanotechnology can improve vaccines, including vaccine delivery without the use of needles. Nanotechnology also offers future transportation benefits, environmental remediation, and a multitude of electronic and energy applications. Many scientists are investigating new ways to develop clean, affordable and renewable energy sources, along with means to reduce energy consumption and lessen toxicity burdens on the environment. Energy innovations such as more efficient solar panels, stronger and lighter weight wind turbines, lighter car parts and improved fuel efficiency will likely be the face of a future shaped by nanotechnology.
At the forefront of industry attempts to revolutionize transportation and energy outcomes through the use of nanotechnology is Archoil , a leading supplier of progressive, high performance lubrication and fuel treatment products. Changes in diesel equipment design such as the introduction of post-combustion particulate filtration systems (DPF) and hydraulic-electric fuel injection systems (HEUI), as well as the introduction of biofuel and ultra low sulfur diesel blends, mandate progressive solutions to overcome new types of problems. By utilizing specific elements such as potassium borate, hexagonal boron nitrate and tungsten disulfid to decrease friction and corrosion while improving high load carrying capabilities, Archoil has engineered a range of formulations to address lubrication and fuel-related challenges present in modern diesel vehicles. Among these developments is Archoil’s AR9100 a nanoborate-based oil additive that forms a solid boundary lubricating film to reduce friction and provide anti-wear, extreme pressure and anti-corrosion protection to engines, gearboxes and hydraulic systems. This friction modifier improves lubricity by filling surface asperities creating a smooth, low friction, surface. Nanoborate has a lower shear strength than the metal it bonds to so friction between surfaces is reduced. This means less engine noise, better fuel economy and less heat from friction, while also improving power and efficiency. Better for the environment, your engine and you!
Having trouble getting revved up about the encroaching winter season? Chances are your heavy equipment is too! The harsh effects of dipping temperatures, heavy snow fall, cold wind and freezing conditions during the winter can be problematic for people and heavy equipment alike. No need to fret, however, over what mother nature has in store. Preparing your equipment for the elements is as easy as putting on your hat and boots. Just follow these simple steps to put some spring back in your engine and have Jack Frost singing the blues!
Step 1: Treat Your Fuel
Diesel fuels are comprised of paraffin wax that serves as a natural lubricity agent. As the ambient temperature of fuel drops, the wax begins to form large square-shaped structures. These structures can cause fuel to gel, clogging your fuel lines and filter. To protect against gelling, use a cold-flow improver (CFI) or a diesel fuel specially formulated for low temperatures. CFIs include de-icers and wax settling agents which extend the operability of the fuel. When utilized at the recommended treatment ratio, winter fuel treatments, such as Schaeffer Diesel Treat 2000, supports improved fuel economy benefits, faster warm-up, reduced emissions, rust protection and improved cetane ratings. A cetane number (CN) is an indicator of the combusion speed of diesel fuel and compression needed for ignition. As a general rule, the higher the cetane number, the faster the fuel will ignite and the more completely it will burn. These attributes are important because as the fuel burns faster and more completely, the engine experiences faster cold weather start-up, increased performance and lower emissions which can be harmful to the environment. Typically, diesel engines operate well with a CN from 40 to 55 during the winter season. If temperatures drop between -4 degrees and -20 degrees, upgrade from a minimum fuel rating of 40 to a 50 cetane rating.
Step 2: Change Your Filters
Whenever possible, keep extra fuel filters on hand and be sure to empty your fuel water tap before temperatures take a dive. Although fuel gelling can be an issue, it’s freezing water in fuel storage tanks and filtration that typically plugs filters during the early winter months. Replacing water-absorbing filters and draining the water separator regularly can go a long way in helping to avoid damage to engine components such as fuel pumps and injectors.
Step 3: Maintain Your Battery
The battery is arguably the pulse of your engine. Therefore, it is imperative that you care for yours by cleaning the battery terminals and making sure that connections are tight. Conduct a visual inspection of your battery, checking for signs of corrosion, dirt or moisture, as these will drain the battery’s life. As temperatures decline so will your battery’s power. At 32 degrees Fahrenheit, a fully charged battery only has a 65 percent cranking capacity. Your engine’s starting requirements, on the other hand, increase from 100 percent to 155 percent. Therefore, be sure to recharge your battery when its capacity drops below 75 percent. When not in use for an extended period of time, batteries should be removed and stored inside.
Step 4: Check The Coolant System
Preventative maintenance is key. Be sure to check for radiator leaks, plugged or hardened hoses and cracked belts. Tighten any loose hose clamps and check coolant levels and anti-freeze strength. Coolants (or anti-freeze) protect your engine from freezing while defending components against corrosion. In addition, they play a critical role in sustaining overall engine heat balance by removing heat. Your coolant level should be one inch over the top of the radiator core and free of contaminants. Be sure that the coolant you are using has a freeze point conducive to the type of climate you are facing. While water provides the best heat transfer, glycol is also used in coolants to provide freeze protection. Ideally a 50/50 ratio of coolant to water will keep your engine running. However, in colder climates a 60/30 coolant to water ratio is recommended. Additionally, avoid using hard water or water that possesses a high mineral content. Hardness levels below 300 ppm of chloride and 100 ppm of sulfate are suggested for best results.
Step 5: Winterize Your Machine’s Tires
Check your tires daily during the cold winter months, as cooler temperatures can cause tires to lose air faster than in warmer weather. Tires should be checked for proper tire pressure and wear marks. When inflating, do so in a heated area whenever possible to help improve the tire bead seal. Such measures will ensure the proper functioning of your equipment and help you stay on track all winter long.
Haven’t been able to make a clean shot this season? Well, blame it on the gun….really! As it turns out, the problem may not actually be yours, despite what all of your buddies have been telling you. The truth is, a clean rifle is an accurate rifle. Your firearms require cleaning to blast away carbon, grease, powder residue and oil build-up leaving the firearm clean and ready for lubrication. In order to ensure safe and effective cleaning, begin by emptying the chamber and placing your rifle in a stationary device. Next, use a bronze brush with a solvent to go down the bore, one pass down and back, to break up heavy build-up. A gun cleaning solvent should loosen and/or dissolve carbon and/or metal fouling in the bore so that a patch can wipe it clean. Insert it carefully through the breach, toward the muzzle, and retract it. Now you are ready to patch the bronze brush. Slide it gently into the bore, pushing it through and pulling back until your bore is clean. A patch that is no longer stained with heavy black residue is indicative of a job well done.
If you are planning on storing your rifle for awhile after it has been cleaned, consider applying a lubricant to the patch at the end of your brush. Carefully reinsert it into the chamber and bore, push it through and withdraw the brush. This thin coat will help to protect your rifle during the months that you are not using it. Not certain which lubricant to use? LPS 1 Greaseless Lubricant offers short term protection and is safe to use on all parts including bore, buffer tube, pins, springs, trigger components, frame, mag wells, bolt carrier and slide. Additionally, it conditions metal surfaces and reduces wear caused by friction and corrosion. On the other hand, LPS 2 Heavy-Duty Lubricant protects for up to 12 months in storage and will not attract sand, dirt or fouling, so it helps ensure long-lasting, reliable firearm function. Formulated to go on wet and stay wet, LPS 2 coats and lubricates internal parts to prevent binding. Additionally, LPS 3 Premier Rust Inhibitor is an excellent long term storage alternative. It’s soft, waxy film protects and prevents metal from corrosion when stored indoors for up to two years .
As a general rule, clean your barrel every ten shots if you require top accuracy. Be sure to lubricate the areas around rotating parts, such as the bolt and trigger assembly. Also, try to keep grease away from the openings into the firing pin housing and don’t forget to oil the bolt rails and grooves in which they ride. Caring for and protecting your parts will go a long way in maintaining the integrity of your rifle and your reputation!

DIY Tips For Winterizing Your Home….
As temperatures begin to take a dip across the country, people are preparing themselves and their personal property for the forthcoming winter season. According to the U.S. Department of Energy, the typical American family spends about $2,000 per year on their home energy bills. However, about 20% of the air you use to heat your house during the winter is lost through leaks and incomplete sealing on windows and doors. A home energy audit, performed on your own or by a professional, will allow you to pinpoint how much energy your home uses, where your home is losing energy and what actions can be taken to make your home more energy efficient. If opting for a DIY audit, you should begin by checking your home’s exterior enclosure. Identify drafts by using smoke tests near doors, windows, electric outlets, attic hatches, range hoods and plumbing and ceiling fixtures. This can be accomplished through the use of a candle or incense stick. Wherever the smoke wavers, or is sucked out of or blown into the room, there’s a draft and proper measures should be taken to reduce air loss. Next, inspect exposed ducts for dirt, small holes, disjointed pipes and improper insulation. As reported by the Department of Energy, since ducts are typically made out of thin metal that easily conducts heat, uninsulated or poorly insulated ducts in unconditioned spaces can lose 10% to 30% of the the energy used to heat your home. Also, be sure to check insulation R-value or thickness where it is exposed. Pay particular attention to areas around ducts, water heaters, appliances, attics and unfinished basements. Use a ruler to measure and compare your results against those suggested for your region via an insulation calculator. Finally, be mindful of stains on insulation which can be indicative of air leaks from a hole behind the insulation, such as a duct hole or crack in an exterior wall.
You’ve done the legwork. Now what?
Odds are that your home energy audit has exposed the culprits behind those baffling utility bills. While some projects are best left for professionals, there are many that most homeowners can accomplish on their own. Below you will find some simple solutions to winter’s biggest offenders.
Diesel engines and vehicles make up about a third of the entire transportation fleet in the U.S. Used to power diesel cars, trucks, ships, locomotives, farm, construction and mining equipment, the amount of sulfur in diesel fuel is directly linked to the amount of pollution produced when the fuel is burned in the engine. Pollution from diesel exhaust includes soot or particulate matter, hydrocarbons, carbon monoxide, oxides of nitrogen and other hazardous air pollutants, which have proven to have serious human health and environmental effects. In 2006, the EPA issued a mandate requiring that all highway diesel fuel supplied to the market after 2010 be ULSD (ultra-low sulfur diesel), reducing sulfur levels in fuel from as many as 5,000 parts per million (ppm) to 15 ppm for highway diesel vehicles. Between 2007-2014, low sulfur (500 pppm) and ULSD (15 ppm) fuel was phased in for non-road, locomotive and marine diesel fuel as well. Consequently, today’s diesel powered vehicles feature low emission engines that are environmentally advantageous, but more susceptible than ever to diesel fuel related wear. These newer engines contain an emissions-reducing device called a particulate filter that traps the tiny particles of soot in the exhaust fumes. The filter uses a sensor that measures back pressure, or the force required to push the exhaust gases out of the engine and through the tailpipes. The mandate of the EPA to reduce sulfur content of diesel fuels, however, has resulted in the elimination of certain naturally occurring, polar compounds that protect the fuel system from wear by forming a protective layer on the metal surfaces of the fuel injection system. The increased use of the hydrotreating and hydrocracking refining processes to produce the maximum 15 ppm ultra low sulfur diesel fuel causes these naturally occurring polar compounds to become either chemically altered or entirely removed, resulting in the need for diesel fuel additives to enhance the quality and efficiency of fuels. Although, in theory, proper additives should already be mixed into your fuel upon purchase, extensive research has revealed wide gaps in the quality of diesel fuel available in different countries. “Premium” diesel is defined by four properties: cetane number, low-temperature operability, thermal stability and fuel-injector cleanliness, but regulations are lax at best. The number and types of additives can vary considerably and some, such as water removers, are not utilized at all by petroleum refineries. Such substandard fuels have the tendency to wear vital components, cause stickiness in valves and clog filters, potentially resulting in decreased engine life. Aftermarket fuel additives, on the other hand, contain additives that refineries and distributors don’t use, working against the majority of problems related to diesel fuel quality. Among the many benefits that fuel additives offer are:
The EPA regulates additives due to their impact on emissions. Among those registered and deemed compliant with the EPA’s standards are Schaeffer Fuel Additives. Schaeffer products undergo a rigorous testing and development process to ensure quality and compatibility, in addition to stringent performance standards. Schaeffer is commited to manufacturing products that are not only cost effective, but environmentally responsible. Their biodegradable oils provide superior protection in environmentally sensitive areas while protecting equipment and reducing energy. For a current list of registered EPA manufacturers or to learn more about Schaeffer Oil additives be sure to visit the EPA website.
Industries today are toting the advantages of powder coated finishes! A notable alternative to liquid paint, powder coating has gained popularity as a dry finishing process used to protect the toughest industrial machinery, as well as common household items including electronics and appliances. The powder used in this process is comprised of finely ground particles of pigment and resin, which are sprayed onto a surface to be coated and baked to a fluid state. Powder coated products have proven to be more durable and resistant to moisture, chemicals and ultraviolet light than liquid paints, while toting an attractive and high-quality finish. Whereas, standard paints can take days to cure and are dependent on atmospheric conditions, powder coated products are ready to use within 20 minutes of heat curation and produce a much thicker coating that will not sag or run. In addition, powder coatings meet all Environmental Agency Protection requirements for air and water pollution control. These materials are generally free of volatile organic compounds (VOCs) and the potentially harmful solvents found in wet paints, minimizing risks to workers and reducing industrial pollution concerns.
Powder coating can be divided into two primary categories; thermoplastic powder and thermoset polymer. Thermoset powder coating differs from thermoplastic powder in that it undergoes a chemical change as it cures and cannot be remelted or reused. This change is referred to as crosslinking. On the other hand, thermoplastic powders remain chemically unchanged throughout the process and are able to be reused and remelted. This type of paint is generally applied to a part that is is heated to a temperature well above the powder’s melting point, causing the powder to melt and form a scratch-resistant, uniform film of paint.
The four basic resins used for thermoset powders are epoxy, acrylic, polyester and fluropolymer. Polyester resins rank high in popularity among powder coating paints, as they offer excellent corrosion protection and extreme weather protection. On the contrary, expoxy-based powder coating is typically limited to indoor applications due to its ultraviolet and harsh weather sensitivity. In architectural and highly corrosive environments, fluoropolymer powders fare well due to their high quality, weather-resistant finish, while acrylic thermosetting powders offer a chip-resistant, high-gloss finish ideal for the automotive industry.
Powder coating involves a multi-step process which includes part preparation, powder application and high-temperature powder curing. Prior to coating, each part must be properly cleaned of dirt, grease, oil, metal oxides, or other substances that may interfere with the painting process. Poor pretreatment practices may lead to a number of issues including loss of adhesion, pinholing, outgasing, weld pull away and premature coating failure in harsh environments such as salt air. In order to achieve superior performance and weathering characteristics, a good pretreatment, such as etching or phosphating is recommended. Such treatments help prevent flash rust prior to powder coating and provide for long-lasting physical bonds.
Alvin’s Lab-Metal and Hi-Temp Lab Metal may be used to patch, smooth, repair and seal items that need to be powder coated. An ideal filler for dents, voids cracks and other surface blemishes, Lab-Metal Repair and Patching compound adheres well to most clean, dry surfaces and can withstand vibration and other difficult conditions. For powder coating processes running above 425 degree F. Hi-Temp Lab-Metal must be used and applied in thin, 1/4 inch, layers. Allow for a minimum drying time of 24 hours, then heat cure. Lab-Metal, on the other hand, may only be used in instances where metal parts will not be exposed to temperatures topping 425 degrees F. for longer than 20 minutes and should be applied no thicker than 3/8 inch.
Following pretreatment, the object must be completely dried before powder is applied. The most common way of applying a powder coating is through the use of an electrostatic gun. The powder is electrically charged as it is applied to the part, giving each particle of the powder a negative charge. The part being powder coated is electrically grounded as a means of attracting and attaching the powder to the part’s surface. This electrostatic attraction is a key element in the process, aiding the coating evenness and the speed of applying the coating. The result is a uniform coating of dry powder clinging to the part.
Once the part is coated with powder, it must be moved into a curing oven. There the powder gels, flows and cures to produce a smooth, durable powder coat finish. During the curing process, crosslinking takes place. It is at this point that the part can be removed from the oven, cooled in ambient air, and put into service.
