N-5392 is a high-performance combined emulsifier and corrosion inhibitor additive package. This additive is designed to formulate water-based metalworking fluids (MWFs) for various applications. N-5392 is a unique combination of anionic and non-ionic surfactant compounds, biocide, and corrosion inhibitor agents that provide highly stable emulsion concentrates and protect metal surfaces from corrosion during the metalworking process.
