  • Best Practices for 3M 2216 B/A Gray

    *See Terms of Use Below

    1. Surface Preparation

      For high strength structural bonds, paint, oxide films, oils, dust, mold release agents and all other surface contaminants must be completely removed. However, the amount of surface preparation directly depends on the required bond strength and the environmental aging resistance desired by user.

      See Vender data sheet for more information

    2. Application

      Application to the substrates should be made within 90 minutes. Larger quantities and/or higher temperatures will reduce this working time.

      Join the adhesive coated surfaces and allow to cure at 60°F (16°C) or above until firm. Heat, up to 200°F (93°C), will speed curing.

      Keep parts from moving until handling strength is reached. Contact pressure is necessary. Maximum shear strength is obtained with a 3-5 mil bond line. Maximum peel strength is obtained with a 17-25 mil bond line.

    3. Mixing

      These products consist of two parts. Mix thoroughly by weight or volume in the proportions specified on the product label and in the uncured properties section. Mix approximately 15 seconds after a uniform color is obtained.

    4. Clean-Up

      Excess uncured adhesive can be cleaned up with ketone type solvents., When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use. Use solvents in accordance with local regulations.
