Abstract
A composition is disclosed, said composition comprising PA1 (A) a polydimethylsiloxane having a viscosity greater than about 2 cS at 25.degree. C.; and PA1 (B) a polyisobutylene oligomer having a number average molecular weight of about 200 to about 3,000 and having at least one end terminated with an epoxy-containing group, the weight ratio of said polydimethylsiloxane (A) to said polyisobutylene (B) being in the range 1:99 to 99:1.
