  • PROCESS FOR MAKING LOW VOC COATING COMPOSITIONS COMPRISING LOW MOLECULAR WEIGHT CELLULOSE MIXED ESTERS AND LOW MOLECULAR WEIGHT HYDROXY-CONTAINING POLYMERS
    Publication number: 20080069963
    Abstract: A process for reducing the VOC content of a coating composition or a refinish composition is provided. The process comprises contacting at least one hydroxyl-containing acrylic polymer, at least one low molecular weight hydroxyl-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.

  • 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.

  • Low molecular weight cellulose mixed esters and their use as low viscosity binders and modifiers in coating compositions
    Publication number: 20070088105
    Abstract: Cellulose mixed esters are disclosed having low molecular weights and low degrees of polymerization. These new cellulose mixed esters include cellulose acetate propionate and cellulose acetate butyrate. The esters exhibit solubility in a wide range of organic solvents with minimal viscosity increase, are compatible with a wide variety of resins, and are useful in coatings and inks compositions as binder resins and rheology modifiers.
