    Abstract: The invention pertains to aqueous blends of colloidally dispersed polymers for use in making organic coatings which are hard and ductile at ambient temperature, which coatings remain stiff and elastic at temperature well above their film-formation or drying temperature. In particular, the invention relates to specific combinations or thermoplastic blends of polymers of very high molecular weights. Such blends produce smooth, essentially crack-free coatings when dried conventionally under atmospheric pressure. Such blends are capable of developing the desired balance of properties without conventional amounts of volatile organic coalescing aids and without the need for chemical cure.

    Abstract translation: 本发明涉及胶体分散的聚合物的水性共混物,用于制备在环境温度下硬和延展性的有机涂层,该涂层在高于其成膜或干燥温度的温度下保持刚性和弹性。 特别地,本发明涉及非常高分子量的聚合物的具体组合或热塑性共混物。 这种共混物在常压下常压干燥时产生光滑的,基本上无裂纹的涂层。 这种共混物能够产生所需的性能平衡,而不需要常规量的挥发性有机聚结助剂,而不需要化学固化。
