Abstract
Abstract Ultraviolet curable polymerizable systems having a built-in secondary curing mechanism are disclosed. The polymerizable coating system is a one component system comprising at least one alkoxysilyl-urethaneacrylate or methacrylate, an acrylate or methacrylate or vinyl ether diluent. The coating systems may include a polymerization initiator of the cationic or free radical photoinitiator type, and a metal catalyst. The coating system is UV curable, and also possesses an additional cure mechanism.
