ABSTRACT:
This invention discloses a process for applying a rubbery coating to a substrate which comprises: (1) dipping the substrate into a plastisol composition in a manner whereby the plastisol composition is applied to the surface of the substrate, wherein the plastisol composition is comprised of (i) polyvinyl chloride, (ii) from about 70 to about 100 parts of a plasticizer per 100 parts of the polyvinylchloride, (iii) from about 1 to about 3 parts of a stabilizer and (iv) from about 10 to about 30 parts of a highly crosslinked nitrile rubber composition per 100 parts of the polyvinyl chloride, wherein the highly crosslinked nitrile rubber has repeat units which are derived from (a) 1,3-butadiene, (b) acrylonitrile and (c) a crosslinking agent, and wherein said highly crosslinked nitrile rubber has a Mooney viscosity of about 50 to about 120, a swelling index of less than about 10 percent, a mill shrinkage of less than 10 percent and a gel content of greater than 90 percent; (2) removing the substrate from the plastisol composition to produce a plastisol coated substrate; (3) heating the plastisol-coated substrate to a temperature which is within the range of about 150.degree. C. to about 200.degree. C. for a period which is sufficient to fuse the plastisol composition to the substrate producing a rubber-coated substrate. The highly crosslinked rubber compositions of this invention can be utilized in slush molding applications.
