摘要

A tough, durable, high temperature epoxy resin tooling composition for making cast-to-size forming tools. The composition comprises a bisphenol-A epoxy resin, a tri-functional aromatic epoxy resin, an anhydride catalyst, and an imidazole catalyst. The composition may optionally contain a filler system comprising filler particles having different diameters that are interstitially-matched.
