Abstract
Abstract The 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
63 words
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.
Claim 2
Dependent Claim
208 words
The method for glazing a motor vehicle according
to Claim 1 wherein the silicon group containing a hydroxyl
or hydrolyzable group bound to a silicon atom and capable
of crosslinking by silanol condensation reaction is a group
of the general formula: wherein R 1 and R 2 each represents an alkyl group having 1
to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms,
an aralkyl group having 7 to 20 carbon atoms or a
triorganosiloxy group of the formula R 3 3 SiO- (R 3 represents
a univalent hydrocarbon group having 1 to 20 carbon atoms
and the 3 R 3 s may be the same or different); where the number
of occurrences of R 1 or R 2 is 2 or more, they may be the same
or different; X represents a hydroxyl group or a hydrolyzable
group and where the number of occurrences of X is 2 or more,
they may be the same or different; a represents an integer
of 0 to 3, b represents an integer of 0 to 2, and a and b
satisfies a+Σb≧1 ; where m is 2 or more, the species of b
may not be the same; m is an integer of 0 to 19.
Claim 3
Dependent Claim
52 words
The method for glazing a motor vehicle according
to Claim 1 wherein the silicon group containing a hydroxyl
