    • Cured coatings having a high degree of extensibility, gloss retention, good sprayability and other desirable properties are obtained from compositions made by reacting (A) an organic polyisocyanate; (B) a hydroxy-containing material selected from the group consisting of saturated polymeric diols having low glass transition temperatures, saturated low molecular weight diols, and mixtures thereof; (C) a hydroxyalkyl ester of an ethylenically unsaturated carboxylic acid; (D) one or more copolymerizable monomers; and (E) a curing agent. These compositions, when used as coatings, are durable, adherent and highly flexible. The coatings are particularly useful on resilient and rubbery substrates such as EPDM rubber, foam rubber, polyurethane foam, and on metal surfaces, such as mild steel and aluminum.
    • 通过使(A)有机多异氰酸酯反应制备的组合物获得具有高延展性,光泽保持性,良好喷涂性和其它所需性能的固化涂料。 (B)选自具有低玻璃化转变温度的饱和聚合二醇,饱和低分子量二醇及其混合物的含羟基材料; (C)烯属不饱和羧酸的羟烷基酯; (D)一种或多种可共聚单体; 和(E)固化剂。 当用作涂层时,这些组合物是耐用的,粘附的和高度柔性的。 这些涂料在弹性和橡胶基质如EPDM橡胶,泡沫橡胶,聚氨酯泡沫和金属表面如低碳钢和铝上都特别有用。
