T-PRO, part of the T-FENDER line, is a chemical passivation agent developed for metallic substrates which naturally have poor corrosion resistance, like silver, brass, bronze, low karat gold, and some electroplated layers.
By applying T-PRO to these metals, resistance to oxidation (tarnish) is dramatically elevated by providing an invisible layer which seals the substrate from external elements.
Laboratory tests have proven that chemical passivation protects from corrosion originating from hydrogen sulfide, UV radiation, synthetic sweat, and humidity. T-PRO is easy to use, not requiring any electrical current and works simply by heating up the product and dipping in your object.
By adding T-SALT, Legor Group conductive salt solutions, T-PRO can also be used by galvanic process to increase its protection level.
