The Effect of Antiozononts on Rubber-to-Metal Adhesion

摘要

Diene rubber vulcanizates contain free double bonds which are sensitive to attack by oxygen and ozone. Natural rubber (NR), polybutadiene (BR), and blends thereof generally contain active antiozonants, both to protect against the degrading effects of ozone and to improve the fatigue resistance. This investigates the effect of antiozonant level and type on adhesion of an NR/BR blend to metal. Three different adhesive chemistries, representing the current state of the art in solvent based and aqueous technologies are evaluated.
