PSP self-amalgamating tape is a non-adhesive tape with a protective release liner which bonds to itself and not your fittings. Ideal for rigging screws, terminals, on deck electrics and emergency hose repairs. Available in black in 19mm. The tape has no adhesive coating in the conventional sense and unless stretched to about half its width and overlapped will not take effect. The tape chemically bonds itself, moulding to the shape of the job after approximately one hour,forming a waterproof sleeve. It then cannot be unwound and can only be removed by being cut away. Being non adhesive, it leaves no sticky residue after removal.
