Abstract
Abstract PCT No. PCT/JP96/02951 Sec. 371 Date Aug. 28, 1998 Sec. 102(e) Date Aug. 28, 1998 PCT Filed Oct. 11, 1996 PCT Pub. No. WO97/13820 PCT Pub. Date Apr. 17, 1997The present invention has its object to a method for glazing a motor vehicle by direct glazing using a novel curable resin composition. A method for glazing a motor vehicle by direct glazing, which comprises using, as a sealant, a curable resin composition comprising (A) an oxyalkylene polymer having at least one silicon group containing a hydroxyl or hydrolyzable group bound to a silicon atom and capable of crosslinking by silanol condensation reaction, (B) carbon black, and (C) an oxyalkylene polymer not containing a crosslinking group is provided.
