    摘要: 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.

    摘要: New epoxy resins result from dehydrohalogenation of the reaction product of an epihalohydrin such as epichlorohydrin with the reaction product of a trisphenol such as 1,1,1-tris(hydroxyphenyl)methane with dicyclopentadiene or an oligomer thereof. These new epoxy resins are useful in the electronics industry as encapsulants, potting compounds, laminates and the like.
