Understanding the Role of Bonding Gums in Rubber-to-Metal Adhesion

Bonding gums are the critical interface in rubber-to-metal assemblies. Proper selection of bonding agents prevents delamination, improves fatigue life, and ensures components meet performance requirements in high-vibration and high-temperature environments. This guide walks through compound selection, surface preparation, and vulcanisation parameters.
