Abstract

1344037 Porous polyurethane films; laminates POTTERS INDUSTRIES Inc 11 April 1972 [15 April 1971] 16723/72 Headings B5B and B5N [Also in Division C3] A porous polyurethane film is obtained by casting a film of an uncured polyurethane film containing glass beads on to a release surface and then curing the film. The glass beads are preferably spherical and may be present in a proportion of up to 30 parts by weight per 100 parts by weight of the resin. The film may be laminated with a substrate such as cotton duck or with a non-woven bonded fibre substrate, using acrylic or urethane emulsion adhesives. The film may also be attached to a carrier layer by the curing reaction.
