Chemlok® 402 Adhesive Where to Buy
Product Information
LORD 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. Chemlok 402 adhesive can also be used as an additive to tie cements, primarily as a replacement for isocyanates that are widely used in rubber/textile bonding.
A single coat of Chemlok 402 adhesive will bond compounds based on a natural rubber (NR), polyisoprene (IR), styrene-butadiene (SBR), polybutadiene (BR), polychloroprene (CR), nitrile (NBR) and butyl (IIR) to polyester, polyamide, cotton, rayon, and polyaramid. When dried, Chemlok 402 adhesive is tack-free.
Shelf Life
Shelf life is six months from date of shipment when stored 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. During summer months, minimize exposure of the adhesive to moisture by preparing only what is needed for several hours of use.
Once opened, fit the 55-gallon drum of adhesive with desiccant tubes if anticipated contents usage exceeds two weeks.
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, giving excellent adhesion to these materials. 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.
