Best Practices for 3M 443PC
-
Surface Preparation
To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Some typical surfaces cleaning solvents are isopropyl alcohol or heptane.
Carefully read and follow the manufacturer's precautions and directions for use when using solvents.
-
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.
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.
To apply adhesives in a wide web format, lamination equipment is required to ensure acceptable quality
