Abstract
A flexible non-reticulated foam pad having on a surface thereof a polyurethane coating consisting essentially of a cured isocyanate-terminated prepolymer, the penetration of the prepolymer coating being no more than about 50 percent of the thickness of the flexible urethane foam. The coated surface provides an abrasive area which enhances its use in cleaning applications as well as increasing the resistance to tear propagation of the wet foam. In addition, the major portion of the foam pad is available for the release of cleaning and sanitizing agents or the absorption of liquids such as water. The novel foam pads are suitable for household, institutional and industrial use.
