摘要： PURPOSE: To provide the titled adhesive which allows inside mirror to be simply bonded in a trimming step in automobile assembly plates, by adding an epoxy group-terminated silane compd. and a room temperature curable hardener to an epoxy resin.
CONSTITUTION: An adhesive having a glass transition temp. of 50°C or below is obtd. by adding an epoxy group-terminated silane compd. and a room temperature curable hardener to an epoxy resin. Preferred examples of the silane compds. are γ-glycidoxypropyltrimethoxysilane and 3,4-epoxycyclohexylethyltrimethoxysilane. The silane compd. is used in a quantity of 0.1W5.0wt% based on that of the adhesive. When the quantity of the silane compd. is less than 0.1wt%, no effect of improving moisture resistance can be obtd., while when it exceeds 5.0wt%, a cured adhesive loses its flexibility. The hardener is used in a quantity corresponding to the epoxy equivalent of the epoxy resin.
