Chemlok® 259 Adhesive Where to Buy


Product Information

LORD Chemlok® 259 adhesive is a covercoat adhesive designed for use over Chemlok 207 primer. This adhesive system will bond uncured rubber to metal substrates during the vulcanization of the elastomer.

Shelf Life

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

Features and Benefits

Versatile - when used in combination with Chemlok 207 primer, bonds a variety of elastomers (e.g., nitrile, natural, SBR, polychloroprene) to a variety of substrates including aluminum, brass and grit blasted or phosphatized steel.

Chemically Resistant - resists a variety of fluids including ethylene glycol, propylene glycol and silicone oil.

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