tesa® 4657 PV1

Temperature resistant acrylic coated cloth tape (tesa® 4657 low unwinding)

Product description

tesa® 4657 PV1 is a high grade acrylic coated cloth tape. It is based on a 145 mesh woven cotton fabric and a thermosetting natural rubber adhesive.
tesa® 4657 PV1 is a very resilient cloth tape often used for permanent hole covering in automotive applications and masking during industrial painting processes.
