Metgard RP-20 is a water soluble, amine carboxylate, corrosion inhibitor that will provide excellent corrosion inhibition at low concentration levels. Metgard RP-20 dries to a light, clear film that prevents the atmosphere from contacting the parts. At low end concentrations the resulting film allows the application of many foams currently applied to steel in the automotive industry. Metgard RP-20 is safe on all metals but is primarily designed for use on steel. Metgard RP-20 may stain zinc and may darken copper and brass. Metgard RP-20 is also bioresistant to a majority of the organisms that attack organic based fluids.
