Best Practices for 3M Single-Coated Urethane Foam Tape 4108

*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.
  
  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.
