  • Best Practices for 3M 3731

    *See Terms of Use Below

    1. Application

      3M™Jet-melt™ Polyolefin Bonding Adhesive 3731 is designed for applications using a 3M™ Polygun™ EC Applicator at the 4 or 5 module setting or a 3M™ Polygun™ II Applicator.

      Recommended equipment temperature for bulk dispensing 350-375°F (177-191°C).

      Apply to one surface. Make bond as soon as possible. Bond strength is maximized when open time is reduced.

      After bond is made, there is immediate strength and no clamping is necessary.

      Adhesive should be allowed to fully crystallize (possibly up to 12 hours) to obtain full performance properties.
