The demand for pressure sensitive adhesives (PSAs) is on the rise due to their incredible versatility, flexible open times, and varying degrees of tack. Designed for both permanent and removable applications, PSAs adhere to a surface when light pressure is applied, with no need for solvents, water, or heat to activate the adhesion. Unlike liquid adhesives, PSAs do not require any setup or curing time, saving business’s valuable time.
Hot Melt Pressure Sensitive Adhesives
Hot Melt Pressure Sensitive Adhesives (HMPSAs) are well known for their exceptional performance and efficiency in a wide range of industrial applications and consumer products due to their ability to move or flow without heat. Although solid at room temperature, HMPSAs are capable of cold flow under a light finger pressure at room temperature, providing free-flowing liquids that can be dispensed rapidly and precisely to the target bonding site. Hot melt adhesives remain permanently sticky, which allows for excellent adhesion even after the glue has cooled. Upon cooling, HMPSAs solidify to form strong bonds between surfaces.
