CURING OF EPOXY RESIN

摘要

PURPOSE:To obtain a cured material having excellent hardness by curing an epoxy resin at high rate, by blending a liquid epoxy resin with THF in a specific ratio and irradiating the resin with radiation in the presence of a photo- cationic reaction initiator. CONSTITUTION:100pts.wt. liquid epoxy resin (preferably liquid bisphenol A glycidyl ether type) is blended with <=50pts.wt. THF, irradiated with radiation usually at 0.1-50Mrad dose in the presence of a photo-cationic reaction initiator (e.g. methoxyphenyldiazonium hexafluorophosphate) and the epoxy resin is cured. Electron rays from an accelerator is preferably used as the radiation.
