    • Thermoplastic coatings have a high degree of extensibility, gloss retention, good sprayability and other desirable properties are obtained from ungelled, storage-stable compositions comprising the reaction product of (A) an interpolymer of a hydroxyalkyl ester of an ethylenically unsaturated carboxylic acid and a copolymerizable compound, (B) an organic polyisocyanate, and (C) a polymeric polyol of low glass transition temperature. Rather than using the interpolymer itself, it is also possible to form useful products by reacting (B) and (C) with a hydroxyalkyl ester monomer in combustion with another copolymerizable monomer. These compositions when used as coatings are adherent, durable and highly extensible. The coatings are particularly useful on resilient and rubbery substrates such as foam rubber, polyurethane foams and vinyl foam and on metal surfaces such as mild steel and aluminum.
    • 热塑性涂料具有高度的延展性,光泽保持性,良好的喷涂性和其它所需的性能由未凝胶化的储存稳定组合物获得,该组合物包含(A)烯键式不饱和羧酸的羟烷基酯的互聚物和可共聚的 化合物,(B)有机多异氰酸酯,和(C)低玻璃化转变温度的聚合多元醇。 不是使用互聚物本身,也可以通过使(B)和(C)与羟烷基酯单体在燃烧中与另一种可共聚单体反应形成有用的产物。 当用作涂层时,这些组合物是粘附的,耐用的和高度可延展的。 涂层在弹性和橡胶基材如泡沫橡胶,聚氨酯泡沫和乙烯基泡沫以及金属表面如低碳钢和铝上都特别有用。
