  • Best Practices for 3M 442KW

    *See Terms of Use Below

    1. Surface Preparation

      To obtain optimum adhesion, all substrate surfaces must be clean and dry. A typical cleaning solvent is an isopropyl alcohol/water solution with a mixture ratio of 50:50 (rubbing alcohol). 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 improves bond strength.

      Ideal tape application temperature range is 70°F to 100°F (21°C to 38°C). 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 generally satisfactory.
