Adhesive A leads to the adhesion action via reacting with methylene receptor such as adhesive R-20, RE, RS, etc. This reaction will quickly start at the vulcanization temperature. If the reaction occurs before vulcanization, the adhesion action of the matching system will disappear.

During mixing the first step is to add rubber, filler and methylene receptor and mix at the high temperature. At the final stage of the mixing, adhesive A and other ingredients are added.

Uses: suitable for the adhesion between rubber to the copper, zinc coated steel and naked steel. Mainly used in the radial tyre steel cord, bias tyre steel ring, steel reinforced conveyor belt and other rubber to metal compounded products.
