AQUEOUS STAIN BLOCKING COATING COMPOSITIONS |
摘要 |
An aqueous coating composition for blocking stains and a method of using the coating composition is described. The coating composition includes an aqueous dispersion of a copolymer that is derived from a single stage emulsion polymeriza-tion of an ethylenically unsaturated nonionic monomer, greater than 0 and less than 1.5% by weight of an ethylenically unsaturat-ed strong acid monomer or salt thereof, and greater than 1.5% and less than 3% by weight of methacrylic acid. |
