PURPOSE: To provide the subject composition containing a specific epoxy resin, a synthetic rubber, a tackiness-giving resin and a latent curing agent for epoxy resin at specific ratios, having tackiness at normal temperature and curable by heating to form a bond having high shearing and peeling strength. n CONSTITUTION: The objective composition contains (A) 100 pts.wt. of an epoxy resin containing plural glycidyl groups (epoxy groups) in one molecule, (B) 50-100 pts.wt. of a synthetic rubber such as nitrile rubber and chloroprene rubber, (C) 10-100 pts.wt. of a tackiness-giving resin such as rosins (ester) or terpenes (phenolic) resin and (D) a latent hardener for epoxy resin such as dicyandiamide or aliphatic sulfonium salt. n COPYRIGHT: (C)1992,JPO&Japio |
