    • This invention relates to a coating comprising prepolymer and monomers for application onto polyurethane for chemical resistance, abrasion resistance, water proof etc. Usually polyurethane is porous and does not have sufficient stain, abrasion and chemical resistance. The said coatings developed using technology of chemical grafting that involves the use of prepolymers, monomers, catalyst, graft initiator, wetting agents, fillers and other ingredients of the composition. The coating thus obtained when applied on the polyurethane allows obtaining graft polymerization, thereby forming a polymeric film chemically attached to the substrate. The polyurethane substrate is reacted with graft initiator which creates the reaction sites on the substrate via free radical mechanism. This in turn renders the substrate receptive to attachment of monomers/prepolymers forming polymeric film that is chemically bonded to the substrate which has then the desired property in terms of stain resistance, abrasion wear, crock, water, chemical resistance and other properties.
    • 本发明涉及包含用于耐化学品性,耐磨性,防水性等的聚氨酯的预聚物和单体的涂料。通常聚氨酯是多孔的,并且不具有足够的污渍,耐磨性和耐化学性。 使用化学接枝技术开发的所述涂层涉及使用预聚物,单体,催化剂,接枝引发剂,润湿剂,填料和组合物的其它成分。 当涂覆在聚氨酯上时由此获得的涂层可以获得接枝聚合,从而形成化学连接到基底上的聚合物膜。 聚氨酯基材与接枝引发剂反应,其通过自由基机理在基材上产生反应位点。 这反过来使得基材接受形成聚合物膜的单体/预聚物的附着,所述聚合物膜化学键合到基材上,其具有耐污渍性,耐磨损性,耐水性,耐化学性和其它性能方面所需的性能。
