Best Practices for 3M 444PC
To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.*
*Note: Carefully read and follow the manufacturer’s precautions and directions for use when working with solvents.
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.
