ABSTRACT:
A molding composition or encapsulant for an electronic component and its method of preparation provides reduced moisture uptake without undue swelling and comprises melt-blending an epoxy resin, hardener and clay, cooling, adding a catalyst to form an epoxy-clay nano-composite, and combining it with a bulk amount of a filler.
