Tef -Gel ™ is derived from a specially formulated Teflon® paste & is used in high corrosive environments to ensure serviceability & presentation of assembled hardware. Tef-Gel™Applications However, we use Tef Gel in assembly to eliminate the risk of galvanic corrosion between dissimilar metals. This brilliant American-made (as used by the US Navy!) product is difficult to find in the UK, so we decided to sell it to UK yachtsmen. The function of Tef-Gel in eliminating dissimilar metal corrosion is the elimination of electrolytes from entering the interface of the metallic surfaces. Tef-Gel paste contains 40% PTFE powder and 0% volatile solvents, no silicones or petroleum solvents to evaporate, which would leave voids for electrolytes to be drawn into creating a galvanic cell. When both surfaces are coated and mated with Tef-Gel there are no voids for electrolytes (saltwater) to be drawn in by capillary action over extended periods of time. Tef-Gel™ prevents galling of stainless steel, when applied to fastenings by preventing the high friction forming between the threads of the nuts and the bolts.
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. Use mascara brush, bottle brush, or toothbrush to apply a thin coat of Tef -Gel ™ to both the threaded hole and the bolt threads and tighten. (Torque requirements may have to be altered according to application of thread lubricants). Tef-Gel applied to both mating surfaces of nuts and bolts or threaded holes and bolts leaves a layer of 40% solid PTFE within the thread interface, which works as friction barrier. Tef-Gel, which contains 0% volatile solvents, will no evaporate, cold flow, or dry out, giving protection many years later when hardware must be dissembled.
Features
Before application, all surfaces, must be free from any previous corrosion, dust, dirt and any other chemical contaminates. If necessary, prepare all surfaces with Mineral Spirits, (Mineral Turpentine). When assembled hardware and fastenings are finally tightened, there needs to be a visible bead of Tef-Gel™ splayed evenly around the head of the fastener and or the hardware. B. Bedding surfaces: A closely mating surface (10 mils .010 or closer) can be protected from capillary action by applying a thin coat of Tef -Gel ™ with brush, toothbrush, or plastic scraper and assembling the parts and cleaning excess product with mineral spirits or WD-40. Tef-Gel applied to both mating surfaces of nuts and bolts or threaded holes and bolts leaves a layer of 40% solid PTFE within the thread interface, which works as friction barrier.
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.)ULTRA Tef-Gel will protect your boat for as long as you own it, saving you a lifetime of frustration, at least when it comes to boat maintenance. Bottom line: PTFE synthetics have rightfully earned high marks for their anti-seize protection. Best Buy. Conclusion
