3M™ Double Coated Urethane Foam Tape 4008
1/8 in. (3.2 mm) thick 1 in x 4 yd
Open Cell Urethane Foam Flexible Carrier with High Shear, High Temperature Resistant Acrylic Adhesive. Use to Fill Gaps and Bond Irregular Surfaces. Distributes Stress Uniformly Over Bonded Area. Apply by Hand.
3M™ Double Coated Urethane Foam Tapes are conformable foams that offer high shear strength and are available with either a high temperature holding acrylic adhesive system or a rubber adhesive system for bonding to various types of Surfaces for mounting, joining and holding.
The natural colored urethane foam tape products vary in color from white to light yellow. The color will change to light yellow upon exposure to sunlight (ultraviolet radiation). This color change is normal and does not affect tape performance.
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.
• To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Typical surface cleaning solvents are isopropyl alcohol* and water (rubbing 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: Be sure to follow the manufacturer’s precautions and directions for use when
using solvents.
