    Patent number: 5859096
    Abstract: The present invention pertains to a one component curable epoxy resin composition which is storage-stable at ambient temperature and which maintains a post-cured high glass transition temperature (Tg) of above 130.degree. C. and a low coefficient of thermal expansion (CTE) of less than 1.76.times.10.sup.-5 cm/cm/.degree.C. over a temperature range of -30.degree. to 125.degree. C., and thus finds practical utility in tooling applications. The epoxy resin composition comprises an epoxy resin or mixture thereof, a multifunctional epoxy resin diluent, a boron trichloride amine complex, and at least one filler selected from the group consisting of a silica or a silicate.
