Ultraviolet curable polymerizable coating and potting system having a built-in secondary curing mechanism is disclosed. The polymerizable coating and potting system is a one component system comprising, in one embodiment, at least one isocyanate-capped polyether diol and triol, an acrylate or methacrylate reactive diluent, and a polymerization initiator of the photo-initiator type. The polymerizable coating and potting system comprises, in a second embodiment, at least one urethane-acrylate or methacrylate, an acrylate or methacrylate compound containing an allylic group; a non-allylic acrylate or methacrylate diluent, a polymerization initiator of the photo-initiator type, and a metal-drier. The coating systems are uv curable, and also possess an additional built-in cure mechanism which assures complete cure even of unexposed (shadow) areas. |
