  • Best Practices for 3M 3747

    *See Terms of Use Below

    1. Surface Preparation

      Surfacesmust be clean, dry and dust free. Wipe with a solvent such as isopropyl alcohol for plastic, metal and glass substrates to remove oil and dirt.

    2. Application

      3M™Hot Melt Adhesives are designed for application with a 3M™ Hot Melt Applicators. Read and follow the precautions and directions for use in the user’s manual before operating the applicator. 3M™ Hot Melt Adhesives are applied at 350-385°F. Adhesives yield approximately 430 linear feet per pound of adhesive when extruded as a 1/8” diameter semi-circular bead. Extruded bead sizes can be customized using 3M™ applicator tips.
