METHOD OF BONDING VULCANISABLE ELASTOMER COMPOSITIONS TO METALS

摘要

The bonding of a rubber composition to a metal reinforcement, especially a brass-coated steel reinforcement, is improved by including in the rubber composition prior to vulcanisation: (a) a reaction product of a nitroso phenol and a polyisocyanate; and (b) a cobalt or nickel bonding agent. The reaction product used can be a reaction product of 4-nitroso phenol and TDI or MDI. The method is of particular value in producing tyre top steel fabric.
