Abstract
Surface treating articles having varying degree of smear-resistance and their methods of manufacture are presented. One preferred article is characterized by an organic matrix substantially engulfed by a novel, tough, adherent elastomeric resinous binder system comprising a reaction product of either selected from PA1 (1) a polyurethane prepolymer with an amine curative, PA1 (2) a polyurethane prepolymer emulsion with an epoxy-functional material and an amine functional material, and PA1 (3) a polyurethane polymer emulsion with an epoxy-functional material and an amine-functional material in an aqueous system.
