3120 is a polyethylene coated waterproof cloth tape with a high tack pressure sensitive adhesive. Use 3120 for duct sealing, securing wires on film sets, heavy duty export packing and as a plate closure tape for gas fire flues. 3120 is made using a close knit fabric which makes it incredibly strong but still hand tearable. Not only that but this waterproof cloth tape has a service temperature of 100oC which is definately something to boast about. Available in a whole range of colours and sizes for a next working day delivery.
