PRIMER COMPOSITION AND ADHESION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a primer composition showing a good adhesion to various substrates and an adhesion process. SOLUTION: The primer composition contains (A) one or more substances chosen from the group consisting of (a) a saturated hydrocarbon polymer having a silicon-containing group which may be crosslinked through forming a siloxane bond, (b) a polybutadiene polymer having a silicon-containing group which may be crosslinked through forming a siloxane bond and (c) a vinyl copolymer which has a main chain substantially comprising a vinyl copolymer chain and contains at the end of its main chain and/or its side chain at least one silicon- containing group which may be crosslinked through forming a siloxane bond, (B) a bivalent tin curing catalyst and (C) organic titanates.
