NAC’s flash Rust Inhibitor additive is recommended for water-borne coating systems, to stop corrosion formation, Effective reduction of flash-rust formation, stopping corrosion formation, minimization of in-can corrosion, improvement long long-term corrosion resistance, better long-term stability, forming water-insoluble complex in paint film during drying, minimized effect on water sensitivity of paint film. A corrosion inhibitor or anti-corrosive is a chemical compound added to a liquid or gas to decrease the corrosion rate of a metal that comes into contact with the fluid. The behavior of flash Rust Inhibitor is governed by their chemical composition and structure. You will find more useful information in our TDS (technical data sheet) and MSDS (safety data sheet).
