  • Best Practices for 3M Single-Coated Vinyl Foam Tape 4726

    *See Terms of Use Below

    1. Surface Preparation

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

      Be sure to follow the solvent manufacturer’s precautions and directions for use when handling solvents.

    2. Application

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