PURPOSE: To prepare a primer giving a self-restorable, pinhole-free capacitor having high moisture resistance, by compounding a di- or tri(meth)acrylate monomer with benzoin isopropyl ether and benzoyl peroxide. n CONSTITUTION: The objective primer is prepared by compounding (A) 100pts.wt. of a di- or tri(meth)acrylate monomer such as ethylene glycol diacrylate, trimethylolethane trimethacrylate, etc., with (B) 1pt.wt. of benzoin isopropyl ether as a photopolymerization initiator and (C) 1pt.wt. of benzoyl peroxide as a thermal polymerization initiator. The di- or tri(meth)acrylate is pref. the one having a polymerization shrinkage of 9W16%. n COPYRIGHT: (C)1982,JPO&Japio |
