Effect of antiozonants on rubber-to-metal adhesion

Comments Email

Diene rubber vulcanizates contain free double bonds that are sensitive to attack by oxygen and ozone.

Natural rubber, polybutadiene (BR) and blends thereof are generally formulated with active antiozonants, both to protect against the degrading effects of ozone and to improve the fatigue resistance.

This paper investigates the effect of antiozonant level and type on adhesion of an NR/BR compound to metal. Three different adhesive chemistries, representing the current state of the art in solvent-based and aqueous technologies are evaluated.
