RESIN-IMPREGNATED BASE AND ELECTRICAL LAMINATE

摘要

PURPOSE:To provide an electrical laminate of superior resistance to smear and a resin-impregnated base used for the laminate. CONSTITUTION:A curing agent, a reaction product of organopoly-siloxane and phenol resin and/or organopolysiloxane rubber powder surface trated with silane and silicone oil, and if required, a base is impregnated with epoxy resin varnish to which a curing accelerator, a solvent and the like are added to form a resin- impregnated base. Metallic foils are disposed integrally with the upper faces and/or lower faces of required number of the resin-impregnated bases to form an electrical laminate.
