Abstract

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 craft 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.
