Particularly useful in the present invention are the low molecular weight, liquid glycidyl polyethers of dihydric phenols obtained by reacting epichlorohydrin with a dihydric phenol in an alkaline medium. A specific example of a liquid polyepoxide which is useful is "Epon 828," a trademarked product of Shell Chemical Company, which is a pourable (10,000-16,000 centipoises at 25° C.), liquid epoxy resin having a melting point of 8°-12° C., an epoxide equivalent weight of 180-195 and is formed by reaction of 4,4'-dihydroxydiphenol propane or 2,2-bis(4-hydroxyphenyl) propane and epichlorohydrin in a molar ratio, respectively, of about 1:2. Another example is "Epon 830" (Shell Chemical Company), which is a pourable (17,000-22,500 centipoises at 25° C.), liquid epoxy resin having a melting point of 12°-16° C., and an epoxide equivalent weight of 190-198.
