Chemlok® 220 Adhesive Where to Buy


Product Information

LORD Chemlok® 220 adhesive is a covercoat adhesive designed for use over Chemlok 205 primer. This adhesive system will bond a wide variety of elastomers such as natural rubber (NR), styrene-butadiene (SBR), polychloroprene (CR), nitrile (NBR) and polyisoprene (IR) to various metals and other rigid substrates during vulcanization of the elastomer. It is composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.

Shelf Life

Shelf life is two years 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 metals when used in combination with Chemlok 205 primer.

Environmentally Resistant - provides superior resistance to heat, water, salt spray, chemicals, oils, solvents and corrosive atmospheres.

Easy to Apply - applies easily by dip, spray or brush methods.
