ANHYDRIDE-CURED EPOXY RESIN SYSTEMS CONTAINING DIVINYLARENE DIOXIDES

摘要

Epoxy resin systems contain 3 to 35% by weight of divinylarene dioxide resins, based on the weight of the epoxy resins, and an anhydride hardener. These systems offer a desirable combination of low initial viscosity, long open time and then fast cure, and demold easily. These characteristics make the epoxy resins systems highly useful in making fiber-reinforced composites in resin transfer molding processes.
