Abstract
The present invention provides a primer composition comprising(A) a vinyl polymer having a main chain substantially comprising vinyl copolymer chain and at least one silicon-containing group having a hydroxy group or a hydrolyzable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond at the terminal end of the main chain and/or side chain, and(B) (a) a saturated hydrocarbon polymer having at least one silicon-containing group having a hydroxy group or a hydrolyzable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond, and/or (b) a polybutadiene polymer having at least one silicon containing group having a hydroxy group or a hydrolyzable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond,which can remarkably improve the adhesion to various kinds of substrates, and which is particularly useful when applied to the isobutylene series sealing material.
