PURPOSE: To obtain the title adhesive easily spreadable when pressed with an electrode chip and exhibiting strong adhesive force even to an oily steel plate, by using an epoxy resin and a rubber each having specific physical proper ties as main components. n CONSTITUTION: The objective adhesive contains (A) an epoxy resin having a solubility parameter (SP) of ≥9.6 (e.g. bisphenol A-type, cresol novolak-type, polyol-type resin or a resin modified with urethane polymer, etc.) and (B) a rubber having an SP value of ≤8.6 (e.g. styrene butadiene rubber, natural rubber or butyl rubber) as main components. The hardener for the component A is those stable at normal temperature and exhibiting activity at 160W220°C, e.g. dicyandiamide, dihydrazides or guanidines. n COPYRIGHT: (C)1989,JPO&Japio |
