GLOSSY PAINTS CONTAINING EMULSION POLYMERS OF VINYL ACETATE. |
摘要 |
Water-borne paints haing 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.
