3M™ Double Coated Urethane Foam Tape 4008 is an off-white, 0.125 in. (3.2 mm) thick, double coated, open cell urethane foam tape that offers high shear strength. It is ideal for applications such as mounting interior signage and nameplates and areas where 1/8 in. thick foam is needed for gap filling applications.
3M™ Double Coated Urethane Foam Tape 4008 is a 1/8 in. thick tape manufactured with 3M™ Adhesive 100 for a strong, permanent bond that works well with the open cell foam structure to produce high shear strength. This tape offers an ideal solution for a wide selection of bonding issues on various surfaces. This includes both interior and exterior applications where the tape will be protected from the environment.
This tape features a conformable foam and adhesive combination which provides long-term holding at temperatures up to 220°F (104°C). By using a robust, green plaid, densified kraft paper liner, this tape provides you with reliable performance for industrial applications, such as die-cutting and automated dispensers. The liner also helps reduce edge roll and protects the tape from humidity extremes.
3M™ Adhesive 100 is a firm, acrylic, pressure sensitive adhesive system that features high ultimate bond strength, very good high temperature, solvent resistance and very high shear holding power. Bond strength increases substantially with natural aging. 3M™ Adhesive 100 is well known in the industry for environmental and chemical resistance. For many applications, any one of the products in this grouping will perform satisfactorily when exposed to different chemicals or temperatures. The adhesive offers excellent bond to metal and high surface energy plastics and good temperature and chemical resistance.
What is Double Coated Tape?
In general, double coated tape is composed of a foam, paper, film, or tissue carrier that is coated on both sides with pressure sensitive adhesive. The adhesive is protected by a peel-away liner that can be removed at the time of application or left in place until the joining surfaces are ready to be attached. These tapes can be applied by hand or with a dispenser. Double coated tape dispensers are available in a variety of configurations ranging from manual to fully automatic. Applications for double coated tape are found in construction, fabrication, arts, and hobby.
