Abstract
Abstract A curing composition showing improved drying characteristics of an alkyd coating which comprises: (A) an oxyalkylene polymer having at least one silicon atom-containing group which has a hydroxyl group or a hydrolyzable group bound to a silicon atom and is capable of crosslinking by forming a siloxane bond; (B) a polymeric plasticizer and/or a viscous plasticizer; and (C) an air curing compound.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A curing composition having an enhancing effect on the drying characteristics of an alkyd coating, which comprises: (A) an oxyalkylene polymer having at least one reactive silicon atom-containing group, said silicon atom-containing group having a hydroxyl group or a hydrolyzable group bound to a silicon atom, and being capable of crosslinking by forming a siloxane bond; (B) a plasticizer selected from the group consisting of polymeric plasticizers having a molecular weight in the range of 500-15000 and non-polymeric plasticizers having a viscosity of at least 8 poise at 15° C.; and (C) an air curing compound capable of curing said composition by reaction with atmospheric oxygen.
Claim 2
