Use of Adhesion Promoters

    • Recommended For Repair Applications (Cheap security!)
    • Required for polythioethers applied over polysulfides
      Example when applying PR-2001 (Polythioether) over PR-1422 or PR-1440
    • Required for polysulfides to polysulfide of different chemistry
      Example when applying PR-1440 (Manganese Dioxide) over PR-1422 (Dichromate)

Application

Apply a thin coat to the solvent cleaned surface with clean gauze and allow to dry for approximately 30 minutes at standard temperature (77°F at 50% RH). After drying time, wipe off excess with a clean gauze pad and start the sealant procedure. If surface becomes contaminated or sealing is not accomplished with 4 hours after application of the adhesion promoter, repeat priming procedure.

    • Store in original sealed container
    • Discard if cloudy or particles are visible
    • Do not use past its shelf life.
