Chemlok® 6450 Adhesive Where to Buy


Product Information

LORD Chemlok® 6450 adhesive is a high-temperature adhesive used to bond NBR and HNBR compounds to metal. It can be applied as either a covercoat or one-coat adhesive.

When used as a two-coat adhesive system, bonds formed with Chemlok 6450 adhesive and Chemlok 207 primer are resistant to many adverse environmental conditions and offer excellent tear strength.

Elastomers:
Nitrile (NBR)
Hydrogenated Nitrile(HNBR)

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.

Features and Benefits

Versatile – bonds a variety of NBR and HNBR compounds to a variety of metal substrates when used in combination with Chemlok 207 primer; can be used as a one-coat adhesive.

Chemically Resistant – resists a variety of fluids, including oils and fuels, and various aqueous environments.

Environmentally Resistant – provides excellent resistance to water, humidity, salt spray and high temperatures.
