3m x 25mm Self Amalgamating Tape

Our Self-Amalgamating Tape is often referred to as “magic tape” by tradespeople because of its unique bonding properties. Unlike standard tapes, it has no adhesive coating; instead, when stretched and wrapped around an object, it undergoes a chemical process to fuse (amalgamate) into a single, solid, rubbery mass. This creates a seamless, void-free layer that is completely waterproof and airtight. It is an essential item for any emergency repair kit. It is widely used for sealing leaking pipes and hoses under pressure, waterproofing electrical connections in outdoor environments, and protecting metal fittings from corrosion. Because it does not rely on glue, it can be used on wet surfaces and leaves no sticky residue behind if it needs to be cut away later. The tape is highly insulating and resistant to a wide range of chemicals, oils, and UV light. Its incredible elasticity allows it to conform to irregular shapes, such as bolt heads or pipe joints, providing a tight, protective skin that traditional PVC tapes simply cannot match. Self-Fusing Technology: Bonds to itself within minutes to form a solid, homogeneous rubber seal. Watertight & Airtight: Perfect for stopping leaks in plumbing, radiator hoses, and garden pipes. High Dielectric Strength: Provides excellent electrical insulation for high-voltage cables and outdoor wiring. No Adhesive Residue: Since it only sticks to itself, it won’t damage the surface it is protecting. Weather & UV Resistant: Remains flexible and effective in extreme temperatures and direct sunlight.
