The utilization of rubber dates as far back as 1770, when, presumably, English scientist, Joseph Priestly, discovered that it could be used to “rub” away the marks left by pencils. During those times, rubber was derived naturally from a milky liquid (latex) produced under the bark of the “cahuchu” (or rubber tree) in tropical regions of South America. Used by the indigenous peoples of the Americas to make bouncy balls, waterproof handmade buckets, pails, clothes, shoes and more, the use of this naturally occurring substance soon became widespread. During World War II, the demand for rubber in the United States began to outweigh the available supply due to the country’s separation from its sources in the Pacific. As a result, the American government began to look toward the development of synthetic alternatives to meet this growing need. Between 1941 and 1945, synthetic rubber production increased from 8,000 to 820,000 tons. Today, there are approximately twenty varieties of synthetic rubbers being manufactured throughout the world including acrylic, isoprene, polysulfide, nitrile, butadiene, butyl and silicone.
How rubber is used in today’s ever evolving world, depends largely on the physical and chemical properties of the material. The fact that rubber can be either hard or soft, significantly increases its functionality and range of applications. Hard rubber is used on the rigid outer surface of your vehicle’s tires. It’s strength, water and heat resistance benefits make it an ideal material for tire production. On the other hand, flexible, butyl rubber, is used on the inner portion of tires, as its airtight properties trap gases so tires stay inflated longer. Soft rubber is also used in the manufacturing of mats, protective gloves, adhesives and paints, while harder rubbers are utilized in the production of rigid inflatable boats, roofing membranes and flooring.
Perhaps one of the most innovative applications of rubber in recent times involves the development of a product called Rubber In A Can. Used to fill in, and seal, cracks, leaks and small holes, rubber in a can comes in an easy to spray aerosol canister. This black, rubberized liquid, creates a tight rubber surface drying to a flexible, rubberized watertight coating that will not crack, peel or chip in either hot or cold temperatures. Long lasting and durable, spray rubber in a can may be used on gutters, duct work, pvc pips, cars, weld joints, wheel wells, truck beds, foundations, gas tanks, driveways, HVAC equipment and more. This flexible liquid rubber can be painted once dry and will adhere to any metal, concrete/asphalt, or rigid plastic surface. To use, shake well and apply to a clean, dry surface (temperature should be above 50 degrees Fahrenheit). Hold the can 10-15 inches away from the surface, applying multiple coats. For optimal performance benefits, do not overspray as thick coats may take longer to dry and can result in dripping or sagging of vertical surfaces. After each use, invert can and spray one quick burst to clear nozzle.
On Labor Day we take “time time off” to honor the contributions of many hardworking Americans. Although Labor Day may be rooted in lofty ideals, for many, it serves as a day to chip away at unfinished home improvement projects, much like “Tim the Toolman Taylor”. The projects that you were going to complete, when summer was on the horizon, are now staring you dead in the face. And as if you didn’t already feel inadequate enough, you now have Pinterest to thank for all of the “inspiring” DIY ideas that your wife has pinned to your Lazy Boy recliner. Thankfully, we’ve got you covered. Here are some great “tools” to help you get started and rest easy this holiday weekend.
The Table Saw
Although table saws have become a subject of concern in recent years, due to the number of injuries resulting from their use, they are still, undoubtedly, one of the most powerful pieces of equipment available for DIY aspirers. The most versatile and productive of all woodworking machines, this single tool can rip, cross-cut, miter-cut, square, dado, rabbet, and even apply shapes to edges of wood stock. Table saws can be used to cut sheet plastic, aluminum, melamine and even tile. It is important, however, that you understand which blade to use, as dull, or unbefitting blades, can compromise your safety on the job and the quality of your work. Consider the materials that the blade will be used to cut and what type of saw it will be used in. As a general rule, blades with more teeth result in a smoother cut, and blades with fewer teeth remove material faster. In addition, the size of the gullet, tooth configuration and hook angle factor are all critical components of selecting the appropriate blade for your job. Be sure to keep the area you are working in clean and free from dust. Allowing debris to build up around your saw is hazardous and should be avoided. Products, such as GlideCote, by Bostik, feature a unique technology that drastically reduces sliding friction and eliminates surface “hang ups” on table saws while repelling dust, dirt and moisture. Furthermore, riving knives, when properly adjusted, greatly reduce the possibility of kickback, which is the most common injury resulting from the use of table saws. Located behind the blade, the riving knife holds the saw kerf open and prevents the stock from closing in on the blade and binding.
The Adjustable Wrench
Also recommended for DIY “enthusiasts” is an adjustable wrench, sometimes referred to as the “irreplaceable wrench” due to its tremendous versatility. Adjustable wrenches may be used for a multitude of home improvement projects, as they have an modifiable “jaw” that can accommodate nuts and bolts of various sizes. Engineered to move in only one direction, the adjustable wrench limits the amount of stress placed on the screw that sits just below the head of the wrench. Due to the wrench’s slightly offset head, loosening and tightening is also easier. Adjustable wrenches come in three different varieties; the crescent wrench, perhaps, being the most common. These wrenches are available in multiple sizes and work well on pipes, faucets, bike and vehicle repairs. The monkey wrench is ideal for bathroom and kitchen home repairs, such as toilet seats, drains, the kitchen sink, garbage disposal and showers. Its long handle allows users to apply their weight to the wrench, unquestionably tightening objects into place. The final type of wrench is referred to as a pipe, or “Stilson”, wrench. These wrenches are typically used to tighten or loosen pipe joints. They have a self-tightening adjustment that makes them ideal for use on both small and large pipes.
Spray adhesives disperse in fine droplets to provide a thin, uniform bonding surface. They can be used as a substitute for hot glue, tape and other adhesives in projects ranging from wallpaper borders to the making and decoration of furniture. Spray adhesives boast varying degrees of adhesive strength, so one must first consider the application of these products before making a purchase for their project. Some spray adhesives are designed for use with only one or two materials, while others can bond to a variety of surfaces. Drywall tinted adhesive, for example, is used to attach plastic corner beads to drywall, while rubber and vinyl spray adhesives are formulated to adhere to leather, laminate, wood, rubber, and plastic products. To use, prepare the work surface in advance by making sure that the area is free of dirt, oil or moisture. Next, protect yourself and the surrounding areas and make sure that there is adequate ventilation, as spray adhesives emit fine particles that can be inhaled. Apply a thin strip of the adhesive to a test area before using and read instructions completely. Once tested, spray light, even, coats to the entire surface. Be sure to hold the can upright and spray from a recommended distance of approximately 1/2 foot for optimum coverage.
Although the application of anti-seize compounds is widespread and varied across industrial environments, the use and selection of these products is often misunderstood. Anti-seize compounds, which are engineered to prevent the corrosion, galling, seizing, and stripping of bolts and fittings, are as diverse as their operations and must be properly chosen to ensure product success. Consider first, that anti-seize compounds are formulated from a variety of agents including copper, aluminum, graphite, zinc, molybdenium disulfide and nickel. The composition of your product will have a direct influence on how effective that compound is in harsh industrial settings where high temperatures and exposure to chemicals can lead to complications with the seizing and galling of fasteners. Be sure to check your product’s temperature rating and metallic composition to be certain that you are choosing the appropriate blend for your job.
Some Things to Remember:
– As a rule, nickel can withstand extreme high temperature applications up to 2,600 degrees Fahrenheit and is chemically nonreactive.
– Similarly, molybdenium disulfide (Moly) is chemically static and can withstand temperatures up to 2,400 degrees Fahrenheit.
– In standard settings ranging from 1,500-1,800 degrees Fahrenheit, anti-seize compounds composed of aluminum or copper tend to work well but, due to their reactive properties, should not be exposed to substances such as ammonia and acetylene.
– Zinc and copper based anti-seize lubricants are not recommended for use with stainless steels.
– Graphite based anti-seize compounds may be utilized where electrical conductivity is required, or in temperatures up to 2,000 degrees Fahrenheit.
In addition to composition, the application of anti-seize compounds is also of high significance, as issues can arise from improper application of these products. Anti-seize compounds serve as a lubricant and are applied to the threads of bolts and other mechanical fasteners to eliminate corrosion that causes a fastener to “seize” over time. When pieces such as these lock, the removal of a piece of equipment, or any of its components, becomes very difficult. To avoid such issues, anti-seize lubricants should be applied to the plain part of the bolt and under the head, thread, the face and both sides of the nut, plus all parts of the washer, if used. Doing so, eliminates the risk of mechanical seizing due to metal-on-metal contact. Subsequently, anti-seize compounds can also serve as a barrier to water penetration since the threads are sealed by the use of the compound. In marine environments, petroleum or synthetic blends of anti-seize are used to seal the thread or other joints. In operating environments such as these, a water washout product is required and can be tested according to ASTM D1264, “Standard Test Method for Determining the Water Washout Characteristics of Lubricating Greases”.
Advancements in LED technology are having a significant impact on energy consumption in the United States. With products boasting up to 85% energy savings, extended operational lifetimes and low carbon dioxide emissions, it is no surprise that LED flashlight bulbs have also gained immense popularity with consumers as a portable lighting option. LED flashlights emit light through a light-emitting diode (LED), rather than a traditional filament wire which depends upon electricity from the batteries to heat the wire and, consequently, produce light. With LED alternatives, energy is conserved and bulbs do not need to be replaced regularly due to burned out wires. LED flashlights, in fact, only draw 5-10% of the the power of an equivalent light bulb and can hold up under 5-10 years of consistent use!
Distinguishing between truth and hype, however, can be tricky in a market saturated with products toting superior performance, durability and prolonged battery life. When determining which LED flashlight is right for you, the following factors should be duly noted.
Aside from the aforementioned characteristics, the type and availability of batteries for your flashlight is also worth noting. Some available options include disposable, rechargeable and renewable batteries. Although conventional alkaline batteries, such as AA or AAA, are readily available and have a longer shelf life, they are more prone to leaking if stored for long periods of time. On the other hand, built-in, rechargeable lithium batteries pack a heavier price tag, but limit waste and render lower operational costs over time.
The type of flashlight that you ultimately choose to purchase will depend on your unique needs. LED flashlights come in a variety of sizes and weights, ranging from tiny coin cell key chains to large, stand-mounted work lights that are perfect for industrial applications. Larger flashlights are typically tougher and exhibit longer run times due to their larger battery capacity, while plastic bodies are lighter, but far less durable. Understanding these various components, however, will take you a long way in finding the flashlight that is just right for you.
The versatility of oil-based paint markers have made them an ideal solution for many industrial applications that require a specialized paint marker to withstand harsh environmental conditions. Ideal for use on a variety of surfaces including metal, wood, iron, plastic, glass, rubber and cloth, these markers tote excellent durability and wear resistance from common solvents and extreme temperatures. Although some paint markers come with an already primed paint tip, most solvent-based paint markers do not. To use these markers, first shake and mix thoroughly before removing the paint cap. Next, push down gently on the spring loaded tip and pump it once. This process will help move the paint from the barrel of the marker to the non-charged empty tip. However, you may notice that no paint appears at first. Be patient and do not over-pump. Repeat one or two additional times, until you see the paint begin to materialize. Once your work is complete, be sure to put the cap back on tightly. When not in use, paint will harden when exposed to air. This hardened tip can obstruct the flow of additional paint through the marker making it unusable. Look for caps with vapor seals which will are designed to keep the air out and help extend the life of your marker.
Although the uses and applications of oil-based paint markers extend well beyond the industrial realm, users must be mindful of the fact that many oil-based markers contain toxic chemical solvents and should not be used by unsupervised children. Fortunately, manufacturers such as Markal, now offer xylene free paint products that help reduce user health risks and and eliminate California Proposition 65, EPA HAPS and SARA 313 concerns in the U.S.A..
Did you know that there are more than 200 diseases spread through food alone? The CDC estimates that each year roughly 1 in 6 Americans (or 48 million people) get sick, 128,000 are hospitalized, and 3,000 die of foodborne illnesses. Everybody has a role to play in keeping food safe, including governments, industry, producers, academia and consumers. It is important that we, as producers and consumers, not only understand how to handle food safely, but also familiarize ourselves with common hazards that may present indirect health risks. For the most part, we take great care to handle, prepare and store food in ways that make it safe for us to eat. We make sure that our foods are cooked at proper temperatures, use clean water and take appropriate measures to keep raw foods away from cooked foods in order to prevent contamination. Although we take great strides to assure that food is handled safely, did you realize that just about every area of a food processing facility comes into contact with chemicals that present a potential cross contamination risk? Think about it. Everyday our food is being produced on equipment that requires the use of chemicals, anti-rust products and cleaning agents to properly maintain and operate such machines. In an effort to combat these potential hazards, in 1999, the USDA developed product registration codes to ensure that all products intended for specific applications are reviewed equally against the necessary criteria for that product’s end user. Today, NSF International, a not for profit health organization oversees the evaluation of food grade lubricants and other food processing substances. In order to register a food grade product, manufacturers must submit their product formulation and label to the NSF, where it is subject to independent review before being approved and listed. When sourcing out chemicals to use in the food industry it is critical that you acquaint yourself with the following product category codes and their acceptable applications in an effort to help protect public health and safety.

The cosmetic isles in every store are amok with products that boast their age defying powers and skin solution capabilities. With so many choices, how do you begin to choose the brand that is best for you? To begin with, it is important to note that moisturizers can be categorized into four different types; occlusives, humectants, emollients and rejuvenators. Occlusives prevent evaporation from the skin by forming a layer on the surface of the skin that repels water and provides an external barrier to water loss. On the contrary, Humectants work to increase the water content of the skin by enhancing water absorption from the protective outer layer of the skin into the epidermis. The third class of moisturizers, emollients, fill in any spaces or gaps between skin cells that are missing moisturizing lipids, such as fats and oils. Finally, rejuvenators are designed to replace crucial proteins in the skin. (Source: Nolan, K. and Marmur, E. (2012), Moisturizers: Reality and the skin benefits. Dermatologic Therapy, 25: 229–233. When choosing between these various groups of moisturizers there are several factors to take into consideration. First, consider the environment that you live in. Occlusives are most effective in humidity void regions while humectants, which absorb water from the air, depend upon high humidity levels. When browsing for moisturizers, keep in mind that lotions, such as Spezial Lotion D by Peter Greven, are droplets of water mixed in oil, meaning that they have a high oil to water ratio and work well in the warm, humid summer months. Creams, such as Lindesa and Spezial Creme C, on the other hand, have a high water and low oil content and are best used during the winter months, as they create a layer of oil that locks moisture in. The water does not evaporate and the skin stays hydrated. (Source: Jeffrey Benabio, MD) In addition, age, genetics, hormones and ethnicity all play a role in determining your skin type and consequently, the type of moisturizer that will ultimately work best for you.
We all know that the sun’s rays can be damaging to the skin, but do you know why? UV radiation is part of the electromagnetic (light) spectrum that reaches the earth from the sun. It has wavelengths shorter than visible light, making it invisible to the naked eye. These wavelengths are classified as UVA, UVB, or UVC, with UVA the longest of the three at 320-400 nanometers (nm, or billionths of a meter). Due to their shorter rays, most UVC is absorbed by the ozone layer and does not reach the earth. Both UVA and UVB, however, penetrate the atmosphere and play an important role in the development of a variety of major skin conditions. A seemingly harmless tan results from injury to the skin’s DNA. In this scenario, the skin darkens in an imperfect attempt to prevent further DNA damage. These imperfections, or mutations, can lead to skin cancer. Caring for your skin when outside is a critical part of staying healthy. When choosing a sun protectant look for sunscreens with both UVA and UVB protection that include UVA screening ingredients such as avobenzone, ecamsule, oxybenzone, titanium dioxide, and zinc oxide. Sunscreens with an SPF of 15 or higher filter 93-98% of the sun’s UVB rays and allow your skin to remain protected from reddening 15-50 times longer.
