  • Method for treating plastic, leather or rubber substrates
    Patent number: 5955536
    Abstract: There is disclosed a method for treating and protecting a substrate, said method comprising coating the surface of said substrate with a composition comprising a blend of(A) a polydimethylsiloxane polymer having a viscosity at 25.degree. C. of 5 to 100,000 cS; and(B) a polyisobutylene oligomer having a number average molecular weight of 200 to 550. The treatment imparts an aesthetically pleasing appearance to the surfaces of plastic, rubber or leather substrates whereby surface gloss is enhanced, but not excessively, as is the case for a comparable all-silicone treating agent.
