Description

ABSTRACT:
Rubber compositions and metal-reinforced rubber ply members have improved metal adhesion and metal adhesion retention. The improvement comprises admixing from about 0.5 to about 10.0 parts per hundred rubber (phr) of bis(2-mercaptobenzothiazato) nickel with a vulcanizable rubber composition prior to combining the metal and rubber and then curing. A method for improving the metal adhesion and metal adhesion retention between a vulcanizable rubber and metal member includes the step of dispersing from about 0.5 to about 10.0 phr of nickel in a vulcanizable rubber composition prior to curing.
