Chemlok® 6253 Adhesive Where to Buy


Product Information

LORD Chemlok® 6253 adhesive is a one-coat adhesive used to bond a variety of vulcanized and unvulcanized rubber compounds to metal. It is formulated without heavy metals and composed of a mixture of polymers, organic compounds and mineral fillers dissolved or dispersed in an organic solvent system.

A single coat of Chemlok 6253 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 metal. These mechanically or chemically treated metals include carbon and alloy steels, stainless steel, aluminum, magnesium, zinc, opper and copper alloys.

For maximum protection or when environmental conditions are severe, Chemlok 6253 adhesive can be used over Chemlok 205 primer or Chemlok 207 primer.
