Double Coated Tapes with Adhesive 300

444 • 444PC • 9009 • 9019 • 9019HL • 9039

Features

• 3M™ Double Coated Tape 444PC is provided on a polycoated kraft liner that

provides moisture stability for large part converting.

• 3M™ Adhesive 300 is a medium-firm acrylic adhesive system featuring both high

initial adhesion and good high temperature holding power.

Application Techniques

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.

To obtain optimum adhesion, the bonding surfaces must be clean, dry and well

unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.*

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.

*Note: Carefully read and follow the manufacturer’s precautions and directions for

use when working with solvents.
