  • Best Practices for 3M 3501 B/A

    *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 removed. The amount of surface preparation depends on the user’s required bond strength and environmental aging resistance., see the vendor technical data sheet for more information.

    2. Application

      Application to the substrates should be made within 6 minutes. Larger quantities and/or higher temperatures will reduce this working time.

      For maximum bond strength, apply product evenly to both surfaces to be joined.

      Join the adhesive coated surfaces and allow to cure at 60°F (16°C) or above until completely firm. Handling strength will be obtained in 20-30 minutes at 75°F (24°C) and a full cure in 24 hours.

      Keep parts from moving during cure. Contact pressure is necessary. Maximum shear strength is obtained with a 3-5 mil bond line.

    3. Mixing

      This product consists of two parts. Measure by weight or volume in proportions specified under Typical Uncured Physical Properties section and mix thoroughly. Resulting color should be uniform. Properly reseal containers. Do not inter-change lids or caps of parts A & B or curing may occur.
