Chemlok® 402 adhesive is a solvent-based, one-coat adhesive designed for bonding textiles to a wide variety of unvulcanized elastomers without the use of isocyanate dips or pretreatments. It is composed of a mixture of polymers, organic compounds and fillers dissolved or dispersed in an organic solvent system.
Chemlok 402 adhesive is used in the production of hoses, V-belts, conveyor belts, diaphragms, air ride suspensions, and other textile-reinforced rubber products. It can also be used as an additive to tie cements, primarily as a replacement for isocyanates that are widely used in rubber/textile bonding. When dried, Chemlok 402 adhesive is tack-free.
Features and Benefits:
• Versatile – bonds a variety of elastomers to a wide variety of textiles during vulcanization of the elastomer.
• Excellent Adhesion – adheres well to RFL-treated fabric or cord. Chemlok 402 adhesive-treated fabric or cord can be bonded immediately following solvent evaporation.
• Convenient – requires only a single coat for most applications, reducing labor, solvent usage, inventory and shipping costs.
Elastomers:
• Natural rubber (NR)
• Polyisoprene (IR)
• Styrene-butadiene (SBR)
• Polybutadiene (BR)
• Polychloroprene (CR)
• Nitrile (NBR)
• Butyl (IIR)
• EPDM Polymers

Shelf Life/Storage:
Shelf life is six months from date of shipment when stored by the recipient in a well ventilated area at 21-27°C (70-80°F) in original, unopened container. Store product in a dry location, away from extreme heat sources. Do not store container outside.
Chemlok 402 adhesive is moisture sensitive. Minimize exposure to moisture by preparing only what is needed for several hours of use.
