摘要:
A thermosetting resin composition which comprises a thermosetting resin and a reactive monoolefin polymer and gives a cured article having a sea-island structure consisting mainly of a continuous phase comprising a cured article formed from the thermosetting resin or from a composition comprising the resin and a hardener and a dispersed phase comprising the reactive monoolefin polymer as the main component, wherein the dispersed phase contains finer dispersed phases therein and/or has at least one interfacial layer present on the whole periphery of the dispersed phase. The thermosetting resin composition is improved in impact resistance, thermal crack resistance, resistance to oxidative deterioration, and resistance to thermal deterioration while retaining intact heat resistance, and is suitable for use in the encapsulation of semiconductors, etc.
摘要:
A waterborne coating composition (10) for application to a donor member surface (15) includes a resin binder (30), a conductive particle material (40), an additional particle material (50) of either (1) graphite particles with a dispersant of polyacrylamide, polyethylene oxide, polyvinyl alcohol or mixtures thereof or (2) crosslinked polymer particles, and water. The waterborne coating composition (10) exhibits superior stability and achieves suitable properties when coated upon a donor member surface, thereby permitting practical replacement of volatile organic components typically used in donor member coating compositions.
