LORD? 7701 adhesion enhancer/surface modifier is a solvent-based surface treatment used for various vulcanized, thermoset, and thermoplastic polymeric materials. LORD 7701 adhesion enhancer/surface modifier chemically alters the surface of the rubber, making it more receptive to bonding.

LORD 7701 adhesion enhancer/surface modifier is used in conjunction with a broad range of LORD adhesives, including epoxy and urethane adhesives, for bonding cured rubber. It improves adhesion to a variety of cured and thermoplastic polymeric materials, including natural rubber, synthetic polyisoprene, SBR, butyl, polybutadiene, neoprene, EPDM, nitrile, polyurethane, styrene-butadiene block copolymers, styrene isoprene rubbers and polyvinyl chloride.

? Versatile - functions as a cleaner and surface conditioner; treats a wide variety of elastomer functional materials.? Easy to Apply - applies easily by wipe, brush, dip or flood methods.? Convenient - requires no mixing.? Improved Adhesion - improves adhesion to cast urethanes and cured rubber.? Fast Drying - adhesion enhancer/surface modifier flashes off within five minutes or less.? Environmentally Resistant - promotes increased environmental resistance by allowing the treated surface to be more easily wet.
