Chemlok® 6956 Adhesive Where to Buy


Product Information

LORD Chemlok® 6956 adhesive is a high performance adhesive used to bond a variety of elastomer compounds to substrates. It is composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.

Chemlok 6956 adhesive will bond compounds based on natural rubber (NR), polyisoprene (IR), styrene-butadiene (SBR), polybutadiene (BR) and polychloroprene (CR) polymers to metals.

Chemlok 6956 adhesive is recommended for use over Chemlok 298 primer. Chemlok 6956 adhesive can also be used without a primer in some applications.

Shelf Life

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