USS Ultra Tef-Gel - 1oz. Syringe
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.
I use it on set screws on bimini frames and on anything else I want to ensure will come apart later. Also great for fasteners installed in aluminum, such as on a mast or boom.
