Chemlok® 7701 Surface Treatment Where to Buy

Product Information

LORD Chemlok® 7701 surface treatment is a solvent-based surface treatment for use on various vulcanized and thermoplastic polymeric materials. Chemlok 7701 surface treatment chemically alters the surface of the rubber, making it more receptive to bonding. Do not apply to metal surfaces.

Chemlok 7701 surface treatment 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.

Shelf Life

Shelf life is six months from date of shipment when stored by the recipient at 21-27°C (70-80°F) in original, unopened container.
