Akron Coating and Adhesives (ACA) announced a line of hot melt adhesives designed to provide a strong bond between a variety of metals and thermoplastics. Thermoplastic elastomers have become increasingly common, and are used in everything from automobiles (weather stripping, gaskets, and seals) to hand grips for tools and appliances.
ACA notes that because these thermoplastics have very low surface free
energy it is difficult to establish good adhesion. Unlike most
adhesives used for this purpose, ACA's products are said to make a bond
that is often strong enough to tear the thermoplastic material without
first applying a primer coat. By eliminating this extra step
manufacturers can cut costs and reduce scrap.
