ABSTRACT:
A blend of epoxide materials is provided which, although essentially free of volatile solvents, is liquid and tractable for coating and related applications at or near room temperature. The epoxide materials include an epoxy prepolymer of the type of glycidyl-bisphenol A resins, epoxidized novolaks, polyglycidyl ethers, and alicyclic diepoxides, blended with a bis(epoxycycloalkyl) ester and in many cases also with a low viscosity monoepoxide in limited proportions. The compositions preferably include additionally a cationic polymerization initiator, preferably a radiation-sensitive catalyst precursor, and epoxide polymers are produced by coating such compositions on a substrate, followed by application of energy, through heating or preferably through irradiation, to effect substantial polymerization of the epoxidic materials of the coating.
