Abstract
The present invention provides an aqueous polymer composition and an aqueous coating composition comprising such aqueous polymer composition that shows balanced stain resistance, freeze-thaw stability, and anti-clogging properties.
Claims9
An aqueous polymer composition, comprising,
- (i) a polymer comprising, based on the weight of the polymer, from 0.1% to 10% by weight of structural units of an allyl alkoxylated phosphate monomer having the structure of formula (I),
- wherein m is from 2 to 5, n is from 0 to 10, 1 is 1 or 2, and Y is —OH or —O−M+, where M is a metal ion or ammonium ion;
- (ii) a functional silane selected from an epoxy functional polysiloxane oligomer, an epoxy functional silane compound, an ethylenically unsaturated compound carrying at least one alkoxysilane functionality, or mixtures thereof;
- and
- (iii) a phosphate surfactant having the structure of formula (V),
- wherein R is a C8-C30 alkyl, AO is an alkoxylated group, b is from 1 to 2, a is from 1 to 30, and N+ is a metal ion or ammonium ion.
