Master Bond has developed one and two component adhesive systems for adhering plastic and rubber surfaces. Compounds are designed to withstand differing coefficients of thermal expansion, resist water/chemicals, high pressures and wear/abrasion. Elastomers such as nitrile, SBR, neoprene, polyurethane, epichlorohydrin and silicone rubbers can bond well to plastics including ABS, acrylics, polyester, nylon, PPO, polyethylene and fiberglass. Proper surface preparation procedures for these applications is essential to optimize cohesive strength properties and for ensuring reliable performance. Use of an adhesive bonding primer will enhance assembly of hard-to-bond substrates.
