Chemlok® 6258 Adhesive Where to Buy


Product Information

LORD Chemlok® 6258 adhesive is a high-performing adhesive that bonds rubber compounds to metal. It is proven in applications that require a combination of strong adhesion with high fatigue resistance and high tensile strength.

Chemlok 6258 adhesive is a non-settling adhesive that provides excellent corrosion resistance when used with mechanically or chemically treated cold rolled steel or aluminum.

Elastomers:
Natural Rubber (NR)
Styrene-butadiene (SBR)
Polychloroprene (CR)
Nitrile (NBR)
EPDM Polymers

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 or use near heat, sparks or open flame.

Features and Benefits

Versatile – bonds a variety of elastomers and can be used over Chemlok 205 or 207 primer for maximum protection or when environmental conditions are severe.

Convenient – requires only a single coat for most applications, reducing labor, solvent usage, inventory and shipping costs; contains high solvent content for roller coat applications.

Process Compatible – provides excellent resistance to sweeping, ideal for transfer or injection molding operations.

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