Abstract:
A composite article is formed by disposing a poly(meth)acrylate layer, formed as the reaction product of at least one acrylate that is polymerized in the presence of an organoborane initiator, on and in direct contact with a low surface energy polymer layer, disposing an epoxide layer on and in direct contact with said poly(meth)acrylate layer, and disposing a hydrolytically resistant layer on and in direct contact with said epoxide layer. The hydrolytically resistant layer is a hydrolytically resistant polyurethane elastomer that is the reaction product of an aliphatic isocyanate component and an isocyanate-reactive component that retains at least 90% of its initial tensile strength after submersion in standardized seawater for 24 weeks. The isocyanate-reactive component is a hydroxyl-functional polymer having an average hydroxy functionality ranging from 2 to 3, wherein the hydroxyl-functional polymer is a dimer diol, a trimer triol, or a combination thereof.
