Abstract: A composite article includes a low surface energy polymer layer, a poly(meth)acrylate layer, an epoxide layer, and a hydrolytically resistant layer. The poly(meth)acrylate layer is disposed on and in direct contact with the low surface energy polymer layer and includes the reaction product of at least one acrylate that is polymerized in the presence of an organoborane initiator, such that the poly(meth)acrylate includes boron. The epoxide layer is disposed on and in direct contact with the poly(meth)acrylate layer. The hydrolytically resistant layer is disposed on and in direct contact with the epoxide and is the reaction product of an isocyanate component and an isocyanate-reactive component reacted in the presence of a curing agent. The isocyanate-reactive component includes a polydiene polyol and the curing agent crosslinks the carbon-carbon double bonds of the polydiene polyol.

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.

Abstract: A composite article has increased pull-off strength and includes a first layer including a low surface energy polymer, a poly(meth)acrylate layer, and an epoxide layer. The poly(meth)acrylate layer is disposed on and in direct contact with the first layer. Moreover, the poly(meth)acrylate layer includes a poly(meth)acrylate that includes the reaction product of at least one (meth)acrylate that is polymerized in the presence of an organoborane initiator. The epoxide layer is disposed on and in direct contact with the poly(meth)acrylate layer. The epoxide layer includes an epoxide. The composite article has a pull-off strength of greater than zero pli measured using ASTM D4541.
