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:

Epoxy-amine compositions employing unsaturated imides

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.

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.
