    Don't Use For As a sealant for other strong oxidizing materials, As a sealant for chlorine materials, Pure oxygen and/or oxygen rich systems

  • Best Practices for Hernon Fusionbond 375

    *See Terms of Use Below

    1. Surface Preparation

      Minimum of surface preparation

      Bonding surfaces should be clean, dry, and free of contamination. Extensive surface preparation is not required for Fusionbond 375 and good bonds can be formed on most substrates after a solvent wipe.

    2. Application

      To assure maximum bond strength, surfaces must be mated within the adhesive's open time. Use enough material to completely fill the joint when parts are clamped.

    3. Mixing

      It is highly recommended that either meter mix equipment or cartridges with static mix nozzles be used to properly ratio and dispense the adhesive. For hand mixing, combine Part A and Part B in the correct ratio and mix thoroughly. Heat buildup during and after mixing is normal. To reduce the likelihood of exothermic reaction or excessive heat buildup, mix less than 100 grams at a time. Mixing smaller amounts will minimize heat buildup.

    4. Curing

      Parts should remain undisturbed during the interval between the adhesive’s open time and fixture time. After the fixture time is achieved the material has reached handling strength. Cure temperatures below room temperature (70ºF to 75ºF) will slow the fixturing time. Temperatures above room temperature will shorten the open time and the fixturing time.

    5. Clean-Up

      It is important to clean up excess adhesive fro the work area and application equipment before it cures.

    6. Removal

      Use Hernon Cleaner 62 for removing uncured adhesive.
