adhesion steel cord 1

[fralupo]

Hy,this's my question:

What's the effect of pH in rubber adhesion to steel cord, is there some correlation between zinc sulfide formation ??

thank

Most black-filled rubber compounds are alkaline unless they also contain silica in which case they would be pH neutral or slightly acid. As far as I know, pH does not affect the formation of ZnS.
