  • Best Practices for Bostik 965FS

    *See Terms of Use Below

    1. Surface Preparation

      Substrates should be free of all loose contamination, greases, oils, etc. Use Isopropyl alcohol or other approved solvent for substrate pretreatment.

    2. Application

      Application-Cartridge-Cut nozzle to desired bead size opening and puncture the inner foil seal. Place cartridge into either a manual or pneumatic caulking dispenser. Apply appropriate pressure to install 965FS so as to assure full contact (surface wetting) to promote sealing and adhesion performance. Tool and finish applied 965FS immediately to promote best mechanical adhesion and cure appearance. Use water or soapy water solution for tooling compound.

      Sausage-Cut tip to desired shape and diameter. Place sausage into a manual or pneumatic caulking dispenser. Apply appropriate pressure to install 965FS so as to assure full contact (surface wetting) to promote sealing and adhesion performance. Tool and finish applied 965FS immediately to promote best mechanical adhesion and cure appearance. Use water or soapy water solution for tooling compound.

    3. Clean-Up

      Cleanup can be done with soapy water, Isopropyl Alcohol, and Bostik® Hand Towels and Specialty Adhesive Cleaner. Cured Marine 965FS can be removed using appropriate mechanical techniques.
