AQUEOUS LATEX COATING COMPOSITIONS |
摘要 |
Disclosed are aqueous latex-based coating compositions which comprise a blend of an ethylene-vinyl acetate emulsion copolymer component and a selected type of acrylic emulsion copolymer component. The acrylic copolymer component comprises primarily acrylate ester co-monomers or acrylic ester co-monomers and vinyl aromatic, e.g., styrene, co-monomers. The blend of these two emulsion copolymer types also contains a specific type of hydrazine-based, water-soluble cross-linking agent which can eventually react with the acrylic emulsion copolymer component. The acrylic emulsion copolymer is one which contains minor amounts of both 1) carboxy functional co-monomers such as itaconic and/or (meth)acrylic acids, and 2) keto- or aldehyde-containing co-monomers such as diacetone acrylamide. Such latex-based coating compositions can be formulated in the form of water-based paint compositions. These paint products provide paint coatings that exhibit desirable dry and wet adhesion characteristics and desirable resistance to blocking. |
