Title:
AQUEOUS POLYMER DISPERSION
Document Type and Number:
WIPO Patent Application WO/2021/022534
Kind Code:
A1
Abstract:
Provided is an aqueous dispersion based on ethylene-vinyl ester copolymers. The aqueous polymer dispersion features good long term storage stability, and weakens water mark phenomenon on the coating film when it is used in waterborne architectural coatings. Especially on the film formed from waterborne emulsion paints in the presence of moisture, the dispersion enables reduced number, color and gloss of water marks.
