  • Glossy paints containing emulsion polymers of vinyl acetate
    Patent number: 6656998
    Abstract: Water-borne paints having an ASTM 60° gloss value of at least 10 are formulated with a latex of a copolymer of vinyl acetate and ethylene or alkyl acrylate having a dry glass transition temperature (Tg) below 20° C. and a latex of a polymer of vinyl acetate having a dry Tg above room temperature but a Tg when wet below 23° C. so that it is film-forming from the latex at room temperature. These paints are suitable for service as satin, semi-gloss or high gloss coatings but preferably are used as semi-gloss paints. The addition of the higher Tg polymer of vinyl acetate to the lower Tg copolymer provides a paint free with low to no volatile organic content but exhibiting improved blocking resistance without significant reduction in gloss.
