Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
92 words
A method of coating the cured product of an oxyalkylene polymer with an alkyd paint comprising (a) combining an oxyalkylene polymer having at least one silicon-containing group that has a hydroxyl group or a hydrolyzable group bonded to a silicon atom and is capable of crosslinking by forming a siloxane bond with a high-molecular weight plasticizer, the amount of the plasticizer being 1-150 parts per 100 parts by weight of the polymer; (b) curing the composition comprising the oxyalkylene polymer and plasticizer; and (c) coating the cured product with an alkyd paint.
Claim 2
Independent Claim
92 words
A method of coating the cured product of an oxyalkylene polymer with an alkyd paint comprising (a) combining an oxyalkylene polymer having at least one silicon-containing group that has a hydroxyl group or a hydrolyzable group bonded to a silicon atom and is capable of crosslinking by forming a siloxane bond with a high-molecular weight plasticizer, the amount of the plasticizer being 1-150 parts per 100 parts by weight of the polymer; (b) curing the composition comprising the oxyalkylene polymer and plasticizer; and (c) coating the cured product with an alkyd paint.
Claim 3
Dependent Claim
19 words
The method of claim 1, wherein the high-molecular weight plasticizer has a molecular weight of from 500 to 15,000.
Claim 4
Dependent Claim
22 words
The method of claim 1, wherein the oxyalkylene polymer contains an average of at least one of said silicon-containing groups per molecule.
Claim 5
Dependent Claim
10 words
The coated product obtained by the method of claim 1.
