tesa® 4657

Temperature Resistant Acrylic Coated Cloth Tape

Product description

tesa® 4657 is a high-grade acrylic coated cloth tape. It is based on a 145 mesh woven cotton fabric and a thermosetting natural rubber adhesive. The acrylic cloth tape is conformable and features a high resistance to paints, solvents, abrasion, and is waterproof. The tape’s high tensile strength, the puncture resistance and the adhesiveness to all kinds of substrates perform well even under elevated temperature. The acrylic coating is highly age-stable, making it very suitable for permanent applications.
tesa® 4657 is a very resilient cloth tape used for temporary and permanent hole covering in automobile production lines and masking during industrial painting processes. Handling and application is easy due to hand-tearability. The tape can be torn in straight edges along the high mesh woven fabric. Residue-free removal is possible, even after high-temperature exposure. The tape is suitable for die-cuts; it is also available in a low unwinding version (PV1) and on paper liner (PV9).
