Abstract: The present invention comprises a radiation immobilizable epoxy formulation which displays improved initial and thermal cycle strengths when bonding different materials such as terephthalate polyesters and aluminum.The composition comprises:(1) a compound or mixture of compounds having a plurality of epoxy groups per molecule;(2) a polyoxyalkylene amine curative for the epoxy;(3) an imide compound selected from those having the formulas; and ##STR1## (4) a photocurable ethylenically unsaturated compound and photoinitiator, said ethylenically unsaturated compound and photoinitiator present in amounts which together are effective to cause the composition to become immobilized when irradiated with actinic radiation.

Abstract: Epoxy resin adhesives in which polyoxyalkylene polyamines are used as curing agents possess significantly improved initial adhesion and thermal shock resistance when mono- or bis-unsaturated cyclic imides are present, e.g. maleimides, bis-maleimides, bicycloheptene discarboximides, and bis-bicyloheptene dicarboximides.

Abstract: Ultraviolet curable polymerizable coating system having a built-in secondary curing mechanism is disclosed. The polymerizable coating system is a one component system comprising at least one urethane-acrylate or methacrylate, an allyl-group containing acrylate or methacrylate monomer, a non-allylic acrylate or methacrylate diluent, a polymerization initiator of the photoinitiator type, and a metal drier. The coating system is UV curable, and also possesses an additional cure mechanism.
