Title: Mono-component epoxy resin mold material
Inventor: HOGE JAMES EDWARD
IPC: C08K3/34
Filed: 1997-03-12
Abstract: PURPOSE: Stocks and plaster metals are used as conventional mold materials, but are inconvenient because of their highly allowable error, expensiveness and slow processing. Also mono-component hardenable epoxy resin mold can reduce the disadvantages, but requires to be preserved under low temperature control condition because of its insufficient preservation stability at room temperature. CONSTITUTION: Mono-component hardenable epoxy resin compositions have preservation stability at surrounding temperature and maintain high posthardened glass transition temperature of over 130°C and low thermal expansive coefficient at from -13 to 125°C. Therefore the composition is used substantially in molding apparatus. The epoxy resin composition comprises 1 or more filler selected from a group consisting of epoxy resin or its mixture, multifunctional epoxy resin diluent, trichloroboron amine complex, and silica or silicate.
