ABSTRACT:
Disclosed is a method for making a laminate having utility in an electrical inductive apparatus, which first comprises coating at least one side of a metal substrate with a solventless liquid resin system comprising an ultraviolet radiation curable acrylic or vinyl monomer and a heat reactive thermoset adhesive resin. The resin system on the coated metal substrate is then exposed to ultraviolet radiation to cure the ultraviolet radiation curable monomer. The resin system is now a tacky solid layer. The laminates so formed can be assembled into components for use in applications such as electric power transformers, ignition coils, generators, chokes, reactors, solenoids ballasts, motors and electronics, in which prior art laminates have been utilized. The assembled laminates are then exposed to sufficient heat to cure the heat reactive thermoset resin and adhere the laminate layers together.
