Bonding rubber to metal is a multifaceted combination of metallurgy, surface science, adhesion science, rubber chemistry, and process engineering, with a multitude of interactions. In all aspects of bonding, scrupulous cleanliness, adherence to process controls and meticulous attention to detail are essential if good adhesion is to be attained on a consistent production basis. In this review article we discuss different aspects of rubber to metal adhesion with emphasis on the mechanisms of rubber to metal adhesion, different types of adhesive systems, and bond properties and bond failure. Breakthroughs in rubber to metal adhesion technologies and the current status of the industry as well as novel alloys used in rubber to metal bonding, especially brass plated steel cords, are highlighted in this review.
Key words: Rubber adhesion; adhesion mechanism; aging; bond failure; brass plated steel cords
