  • Best Practices for Bostik 2402

    *See Terms of Use Below

    1. Surface Preparation

      Surfaces must be clean and grease free. They may be cleaned by abrading the surface with clean emery cloth or by using Bostik 9913 Solvent to remove surface contamination. Solvent cleaning should not be adopted for those surfaces where the bond strength is likely to be affected adversely by the penetration of the solvent into the materials. For maximum adhesion, abrading is preferable to solvent cleaning. Some rubbers (particularly natural) require priming with Bostik 9300 Primer prior to application of Bostik 2402 adhesive. Test strips should be made up and tested to ensure the best bond possible will be obtained. For the strongest adhesion to metal, and some plastics Bostik 9252 Primer must be used. Stir the primers thoroughly prior to the application of a medium brush coat to the prepared metal surfaces. Allow the primer coat to dry for at least one hour before applying adhesive.

    2. Application

      In some cases a single adhesive application to each surface may not be sufficient (e.g. porous surfaces) then multicoat applications may be needed to build up film thickness. In this case, each coat should be allowed to dry for about 40-45 minutes except the final one which should have 10 - 20 minutes. It is always advisable to build up film thickness with a number of thin coats rather than a single heavy coat.

      Allow the 2 films to dry for 10-20 minutes, or until they can be touched with the knuckles without any cement being transferred.

    3. Mixing

      Add approximately 4% w/w Bostik 9101 Curing Agent to 2402 Adhesive and stir in thoroughly for at least 2 minutes.

    4. Clean-Up

      Clean up and thin with Bostik 9913 solvent only.
