Acrylic based aqueous coating composition

摘要

An aqueous coating composition including a pigment and an aqueous acrylic emulsion polymer including, as copolymerized units, from 50% to 99.75% by weight, based on dry polymer weight, monoethylenically unsaturated nonionic (meth)acrylic monomer and from 0.25% to 10% by weight, based on dry polymer weight, monoethylenically unsaturated acid monomer, the polymer having a Tg of -10 DEG C to 35 DEG C wherein the emulsion polymer is formed by a certain emulsion polymerization process at a temperature of from 70 DEG C to 99 DEG C in the presence of a thermal initiator is provided. Further provided is a method for forming a dry coating therefrom.
