Claims
- 1. A method for improving metal adhesion and metal adhesion retention properties between a vulcanizable rubber composition and metal comprising the sequential steps of:
- dispersing from about 0.5 to about 10.0 parts by weight of bis(2-mercaptobenzothiazato)nickel per 100 parts of the rubber component in said rubber composition
- embedding said metal into said rubber composition thereby applying said rubber composition containing bis(2-mercaptobenzothiazato)nickel to said metal prior to curing and
- curing said rubber composition containing said metal.
- 2. A method, as set forth in claim 1, wherein the amount of bis(2-mercaptobenzothiazato)nickel employed is 3.20 parts per 100 parts of rubber.
- 3. A method, as set forth in claim 1, wherein said rubber is selected from the group consisting of natural rubber, synthetic rubber and blends thereof.
- 4. A method, as set forth in claim 1, wherein said metal is selected from the group consisting of brass, zinc and brass-plated and zinc-plated steel cord.
