Best Practices for 3M 9420

*See Terms of Use Below
1. Surface Preparation
  
  To obtain optimum adhesion, the bonding surfaces must be clean, dry, and well unified.
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.
  
  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.
