Tef-Gel has 40% Powder (PTFE and no volatile solvents, silicone oil, which would penetrate the electrolytes. When Tef-Gel is applied to the two metal surfaces in contact, the Electrolytes of sea water can no longer penetrate by capillary action, and this long periods of time. A. bolt or live in aluminium, steel, stainless steel. Use the applicator to apply a thin layer of Tef-Gel on the thread of the bolt and thread holes, and squeeze. B. Plated Surfaces Against One Another: the capillary action by applying a thin layer of Tef-Gel these areas can be protected with a brush, a toothbrush or a plastic palette before assembly. Clean the excess as white spirit. Tef-Gel is not an electrical insulation, and it does not increase the electrical resistance of connections. The PTFE (40%) is an ultra-fine powder that extrude out of the contact surface and the cavities of the surrounding surfaces. Tef-Gel eliminates the weld by corrosion of stainless steel, inconel and other Nickel Alloys. Tef-Gel applied on both nut and bolt or bolt and solid leaves a film of PTFE thread holes, which prevent the weld corrosion. As Tef-Gel contains no volatile solvents, it does not evaporate, does not freeze, will not dry out and protects durably the elements, this allows for easy removal. Tef-Gel is a made with a water resistant coating that prevents oxidation of metal and paste corrosion due to the flow galvaniques between different metals. A small amount of galvanic tef-gel is enough to prevent the exchange of electrons and corrosion that emerges between different metals and carbon materials (aluminium, stainless steel, etc.) Tef-Gel applied on both surfaces and bolt or nut bolt and threaded solid leaves a film of PTFE, which prevent drill steel 18/Corrosion. As tef-gel contains no volatile solvents, it does not evaporates and does not freeze, will not dry out and protects durably the elements, this allows for easy dismantling.
