ABSTRACT:
New epoxy resins are described having high strength and ductility. The novel feature of these new resins is that a normal epoxy resin component is cross-linked with a novel mixture of methyl endomethylene tetrahydrophthalic acid and methyl endomethylene tetrahydrophthalic anhydride. An additional usual anhydride, e.g. phthalic anhydride, may also be present. The products are excellent electrical insulators and are suitable for casting, vacuum filling, laminating, binding, etc.
