Chemlok® 6956 Adhesive Where to Buy


Product Information

LORD Chemlok® 6956 adhesive is a high-performing adhesive that bonds rubber compounds to metal. It is composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.

Chemlok 6956 adhesive is recommended for use over Chemlok 298 primer. In some applications, it may be used without a primer.

Elastomers:
Natural Rubber (NR)
Polyisoprene (IR)
Styrene-butadiene (SBR)
Polybutadiene (BR)
Polychloroprene (CR)

 

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.
