Chemlok 7701 Surface Treatment
Solvent-based surface treatment for enhanced bonding
Chemlok 7701 is a solvent-based surface treatment designed to improve the adhesion of various adhesives to vulcanized and thermoplastic polymeric materials. By chemically altering the rubber surface, it creates a more receptive bonding surface. It's crucial to note that this product should not be applied to metal surfaces.
Chemlok 7701 works effectively with a wide range of LORD adhesives, including epoxy and urethane formulations, enhancing the bond strength for cured rubber and other polymers like natural rubber, synthetic polyisoprene, SBR, butyl, polybutadiene, neoprene, EPDM, nitrile, polyurethane, styrene-butadiene block copolymers, styrene isoprene rubbers, and polyvinyl chloride.

Shelf Life/Storage
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. Avoid storage in lighted areas. Store material in original container or UV-filtering plastic or glass container. Do not store in metal containers. Store Chemlok 7701 surface treatment in a cool, dark area away from oil, grease, sawdust, floor sweepings, easily oxidized organic compounds, ammonia, amines, ammonia salts, and metallic materials. Do not contaminate with water or alcohol.
