  • Best Practices for Bostik Thermogrip 6390

    *See Terms of Use Below

    1. Surface Preparation

      All surfaces should be clean and free of contaminants. If necessary, clean surfaces with solvent.

    2. Application

      Apply the adhesive to the more difficult-to-bond surface. In general, hard, smooth surfaces are more difficult to bond than rough, porous surfaces. Metals should be pre-warmed up to 200°F (95°C) for optimum results. Open-time varies depending on application temperature, amount of adhesive applied, type of substrate and ambient temperature conditions. Mate the surfaces to be bonded as quickly as possible after adhesive has been applied for optimum bond strength. Use firmest pressure practical for object being bonded. Do not move or adjust surfaces after contact has been made, as inferior bond strength will result. Typically, a properly formed hot melt adhesive bond will achieve 50% of its strength after 1 minute, 75% after 1 hour, and 100% after 1 day.
