  • Methods for improving the anti-sag, leveling, and gloss of coating compositions comprising low molecular weight cellulose mixed esters
    Publication number: 20070282038
    Abstract: A process for improving the anti-sag, leveling, and gloss of a coating composition is provided. The process comprises contacting at least one hydroxy-containing acrylic polymer, at least one cellulose mixed ester, at least one crosslinking agent, and at least one curing catalyst to produce the coating composition; applying the coating composition to a substrate; and drying the coating composition; wherein the 20 degree gloss of the coating composition is improved over a coating composition without the cellulose mixed ester.
