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 the reaction product of either PA1 (1) a polyurethane prepolymer, or PA1 (2) a polyurethane polymer emulsion with an epoxy-functional material and an amine-functional material in an aqueous system.
