Adhesion, or lack of it, is one of the most critical attributes for most adhesives, coatings and inks. A variety of options can be explored when it comes to adhesion. Two of the most common types of adhesion are mechanical and chemical. Mechanical adhesion occurs when adhesive materials physically lock into the crevices of the surface. This requires that the substrate surface be physically abraded or chemically etched, unless the substrate has a naturally rough surface.
Chemical adhesion can be improved through the use of coupling agents, such as silane acrylates, or through under curing a primer coating. When improved adhesion was recently required in several different UV-curable applications, a specific material was developed that could be used for a variety of applications.
