FORMULA 319

Citric Acid Passivation

FORMULA 319 is a special, non-corrosive, non-oxidizing, environmentally friendly acid solution for passivating stainless steel. Studies have shown that the ‘natural’ acids in FORMULA 319 are as effective as typical passivation products containing nitric acid in restoring a protective chromium oxide film to the surface of all grades of stainless steel. Use FORMULA 319 after a ‘stripping’ cleaning to passivate tanks and other vessels, vats, valves, and other pieces and parts needing a protective chromium oxide film. Use of this product will conform to ASTM A967 specifications.
