Best Practices for 3M 4408
-
Surface Preparation
To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Some typical surface cleaning solvents are isopropyl alcohol and water or heptane.**Note: Be sure to follow the manufacturer’s precautions and directions for use when working with solvents.
-
Application
Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure develops better adhesive contact & thus 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.

Tensile Strength Test Methods
| Tensile Strength | Test Temperature | Test Method |
|---|---|---|
| 60 psi | 22°C | (“T” Block) 1 in2 (6.45 cm2) Jaw Speed 2 in/min (50 mm/min), Adhesive strength exceeds foam strength |
Shear Strength Test Methods
| Shear Strength | Type | Test Time | Test Temperature | Test Method |
|---|---|---|---|---|
| 500 (g) | Static shear strength | 360,000 sec | 22°C | As measured by static shear weight held for 100 hr, 1/2 sq.in overlap |
| 125 (g) | Static shear strength | 360,000 sec | 49°C | As measured by static shear weight held for 100 hr, 1/2 sq.in overlap |
