EPON™ Resin 164 and 165

Description

EPON™ Resins 164 and 165 are solid multifunctional cresol novolac epoxy resins (see molecular structure). These resins combine the high thermal stability of the cresol novolac backbone with the versatility, reactivity and chemical resistance of epoxy resins. They are used where improved properties of cured epoxy resin systems are needed, particularly at elevated temperature and where stability of electrical properties under humid conditions is required. They find application in electrical laminates, molding compounds, high-performance aerospace composites, high- temperature adhesives, powder coatings and tooling.
