Abstract
Official abstract text for this publication.
Scratch resistance and/or reflow of a refinish topcoat is improved by preparing the topcoat from a refinish topcoat coating composition comprising an unsaturated fatty acid ester polyol that does not undergo oxidative cure when the applied refinish topcoat coating composition is cured.
First claim
Opening claim text (preview).
What is claimed is: 1. A refinish, multi-component topcoat coating composition comprising: a first package comprising: (a) an unsaturated fatty acid ester polyol having a plurality of hydroxyl groups; and (b) an acrylic polymer resin comprising: a first styrenated acrylic resin having a hydroxyl number of 136 mg KOH/g, a number average molecular weight of 1,400 daltons, and a glass transition temperature of 24° C.; and a second styrenated acrylic resin having a hydroxyl nu…
