HOT MELT ADHESIVES
Hot adhesives, also known as hot melt adhesives, are thermoplastics applied in molten form, which solidify on cooling to form strong bonds between a wide range of materials. They are manufactured and sold in solid cylindrical sticks of various diameters, designed to be applied using a hot glue gun.
This type of adhesive is popular among a number of applications due to its ease of use and the wide range of common materials it can join. GRR has a wide variety of 3M Hot-Melt Adhesives and 3M Polygun Applicators, which are engineer to be advanced systems to help you improve productivity, lower cost and minimize waste.
