摘要： An aqueous coating composition having improved adhesion to friable surfaces is provided. The aqueous coating composition includes a plurality of polymeric particles having a particle size of less than 120 nanometers, and containing at least two polymers, one of which contains, as polymerized units, acid functional monomers, water soluble monomers, or both. Optionally, the aqueous coating composition includes a nonionic surfactant. In addition, a method for improving adhesion to friable surfaces by using the aqueous coating compositions of the invention is provided.

摘要： An aqueous polymer blend composition including a predominant amount of soft polymer particles and a minor amount of hard polymer particles is provided. The soft polymer particles contain, as copolymerized units, 70 to 99.7% by weight monoethylenically unsaturated (meth)acrylic monomer and from 0.3 to 10% by weight monoethylenically unsaturated acid monomer, based on weight of soft polymer particles. The soft polymer particles are made by a select process including redox polymerization or polymerization in the presence of excess unreacted monomer. The aqueous polymer blend composition is useful for preparing dry coatings having improved dirt pickup resistance and acceptable scrub resistance. A method is provided for preparing a dry coating from the aqueous polymer blend composition.
