Chemlok® 252X Adhesive Where to Buy


Product Information

LORD Chemlok® 252X adhesive is a general purpose one-coat adhesive that will bond a variety of vulcanized or unvulcanized rubber compounds to metal or other dissimilar rubber compounds. It is composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.

A single coat of Chemlok 252X adhesive will bond compounds based on natural rubber (NR), polyisoprene (IR), styrene-butadiene (SBR), polybutadiene (BR), polychloroprene (CR), nitrile (NBR), butyl (IIR) and EPDM polymers to metals. These metals include carbon and alloy steels, stainless steel, aluminum, copper and copper alloys, magnesium and zinc, as well as a variety of plastics.

For maximum protection or when environmental conditions are extremely aggressive, Chemlok 252X 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 or use near heat, sparks or open flame.

Features and Benefits

Versatile - bonds a wide range of elastomers and tolerates a variety of differences in compounding.

Non-Chlorinated Solvent System - suitable for solvent incineration, saving cost of recovery equipment.

Convenient - requires only a single coat for most applications, reducing labor, solvent usage, inventory and shipping costs.
