Chemlok® 256 Adhesive Where to Buy
Product Information
LORD Chemlok® 256 adhesive is a general purpose one-coat adhesive used to bond rubber compounds based on natural rubber (NR), styrene-butadiene (SBR), polychloroprene (CR), nitrile (NBR) and EPDM polymers to metal during vulcanization. It is composed of a mixture of polymers, organic compounds and fillers dissolved or dispersed in an organic solvent system.
For maximum protection or when environmental conditions are extremely aggressive, Chemlok 256 adhesive can be used over Chemlok 205 primer.
Shelf Life
Shelf life is one year from date of shipment when stored at 21-27°C (70-80°F) in original, unopened container. Do not store near heat, sparks or open flame.
Features and Benefits
Easy to Apply - high solids content allows for roll coating application.
Convenient - requires only a single coat for most applications, reducing labor, solvent usage, inventory and shipping costs.
Process Compatible - resists sweeping; ideal for transfer or injection molding operations.
