Primer composition for bonding polymer composites with urethane adhesives and sealants

摘要

A solvent or water-based primer system to promote the adhesion of polyurethane adhesives and sealants such as polyurethane hot melt adhesives to polymer composite substrates such as FRP and SMC. The primer contains at least one functional polymer, and preferably at least one hydroxyl functional polymer. A method of using the primer system and an article containing the primer system are also disclosed
