摘要：
An aqueous coating composition having improved adhesion to friable surfaces including an emulsion polymer of certain compositions and certain acid numbers having a glass transition temperature of −20 C to 100 C and an average particle diameter less than 120 nanometers; and 0.25-10%, by weight based on emulsion polymer weight, water-soluble alkoxylated amine is provided. In addition a method for for improving adhesion to friable surfaces by using the aqueous coating compositions of the invention is provided.
