  • Best Practices for 3M 927

    *See Terms of Use Below

    1. Surface Preparation

      To obtain optimum adhesion, the bonding surfaces must be clean, dry, and well unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.

      Note: Be sure to follow solvent manufacturer’s precautions and directions for use when using solvents.

    2. Application

      Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure helps develop better adhesive contact and improve bond strength.

      Initial tape application to surfaces at temperatures below 50°F (10°C) is not recommended because the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is satisfactory.

    3. Testing

      3M™Adhesive 300 has relatively good resistance to moderate amounts of plasticizers. Applications may be subjectively evaluated by the user testing the tape in contact with the materials at conditions of 150°F (66°C) for a period of 5-7 days.
