ABSTRACT:
Curable compositions are prepared from reinforced epoxy resin compositions comprising (A) a filler material such as silica flour, (B) one or more epoxy resins at least one of which is a hydrocarbon novolac epoxy resin such as a phenol-dicyclopentadiene epoxy novolac resin and (C) one or more epoxy resin curing agents such as phenol-formaldehyde novolac resin. These compositions are particularly suitable for use in electrical applications such as the encapsulation and subsequent protection of electrical and micro-electronic devices and circuitry and in adhesive formulations.
