Appl. No.:

09/562345

Inventors:

Lloyd Mahlon Robeson - Macungie PA
Lori Anderson Vratsanos - Breinigsville PA
Susan Ann Miller - Orefield PA

Assignee:

Air Products Polymers, L.P. - Allentown PA

International Classification:

C08L 3104

US Classification:

524501, 524524, 524563, 524564

Abstract:

Water-borne paints having an ASTM 60Â 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 (T ) below 20Â C. and a latex of a polymer of vinyl acetate having a dry T above room temperature but a T when wet below 23Â 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 T polymer of vinyl acetate to the lower T copolymer provides a paint free with low to no volatile organic content but exhibiting improved blocking resistance without significant reduction in gloss.
