Title:
COATING COMPOSITION AND COATING FILM OBTAINED FROM COATING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2013/129488
Kind Code:
A1
Abstract:
The present invention addresses the problem of maintaining the thermal barrier performance of an aqueous thermal barrier coating composition for a long period of time by developing an aqueous thermal barrier coating composition that is provided with low contamination properties for the purpose of suppressing deterioration in the thermal barrier performance caused by decrease in the solar reflectance due to adhesion of a contaminant in the atmosphere under outdoor exposure.
The above-mentioned problem is solved by a resin composition for aqueous coating compositions, which contains (A1) a water-soluble and/or water-dispersible resin, (A2) a thermal barrier pigment, (B1) an organosilicate and/or a modified product thereof and (B2) a curing catalyst for promoting the hydrolysis-condensation reaction of an alkoxysilyl group.
