Chemlok 6108GB Rubber-to-Metal Covercoat Adhesive

Chemlok 6108GB is a solvent-based covercoat for bonding elastomers to metal during vulcanization. It is normally applied over Chemlok 205GB primer or Chemlok 207GB primer. One-coat use is possible in selected applications, depending on the rubber compound and process.

• Compatible with a broad range of general-purpose and specialty elastomers.
• Uses a non-chlorinated solvent system.
• Provides resistance to heat, oils, and salt spray.
• Can be applied by spray, brush, or dip.

Natural rubber (NR), polyisoprene (IR), polybutadiene (BR), polychloroprene (CR), nitrile rubber (NBR), styrene-butadiene rubber (SBR), butyl rubber (IIR), and EPDM.

Prepare the metal before applying Chemlok 205GB or 207GB primer. Allow the primer to dry, then apply 6108GB by spray, brush, or dip. A typical dry-film thickness is 17.8–25.4 μm (0.7–1.0 mil). The adhesive cures during rubber vulcanization.
