This box of 90 rolls of 19mm x 5m high quality rubber tape is primarily used to waterproof joints or make temporary repairs to leaking pipes as the bond creates a durable, watertight seal.Self amalgamating tape bonds or fuses to itself when stretched. They do not contain any glue or adhesive ingredients. The bonding occurs once the tape has been wrapped around wires, devices or cables through a process called self-fusing.The tape comes with a thin plastic backing which needs to be removed for the self-fusing process to occur. It sticks only to itself, so make a note of the requirement for a 50% overlap of clean (grease-free) tape.Available in a range of widths and lengths.
