Legor T-Pro Passivation Solution
T-PRO is a chemical passivation agent developed by Legor for metallic substrates which naturally have poor corrosion resistance. By applying T-PRO to the metal, 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 submerging your object. T-PRO is stocked and sold as 5 litre bottles.
