Abstract
A water-borne paint composition including an opacifying pigment, a core-shell polymer with acid functionality, and a polymer polymerized from a group of monomers including a macromonomer having a hydrophobic portion and an alkoxylated portion. The core-shell polymer includes a shell and a core, wherein the weight of the shell is less than 10% of the weight of the core.
Claims20
A water-borne paint composition comprising:
- a core-shell polymer having acid functionality and comprising a shell and a core, wherein the weight of the shell is less than 10% of the weight of the core;
- a polymer polymerized from a group of monomers comprising an unsaturated carboxylic acid monomer, a monoethylenically unsaturated monomer different from the carboxylic acid monomer, and a macromonomer including a hydrophobic portion and an alkoxylated portion that is polymerizable with the carboxylic acid monomer and the monoethylenically unsaturated monomer;
- and
- an opacifying pigment.
