Chemworld ALTO 418 is a unique blend of anti-oxidants and water conditioners designed to provide up to 90 days indoor rust protection by leaving a dry, non-oily, non-waxy clear film on ferrous components. ALTO 418 may be applied by either conventional recirculating spray, manual spray or immersion. The Chemworld ALTO 418 rust protecting film is thin enough not to interfere with normal dimensional measurements. ALTO 418 functions as a clear leak test fluid for underwater pressure testing. ALTO 418 also functions as a sealing rinse for ferrous metal prior to painting for preventing flash rusting during dry down and improving corrosion resistance during storage. Surface pH of the metal will be 8.0 +/- 0.5 after rust inhibitor application
