Profile: Nanjing Shangren Chemical Industrial Co., Ltd. is a supplier of metal cleaning surfactant, cleaning agent. and rust inhibitor. Our water-based metal cleaning agent has the dual function of oil removing & rust cleaning. The product can remove the oil and corrosion of metal surfaces to varying degrees in a relatively short time. LS-403B anti-rust additive is a kind of dehydrated rust inhibitor. The water-based rust inhibitor (dehydration rust inhibitors) produced by adding LS-403 B anti-rust additives can form a chemical anti-corrosion film on the metal surface, and thus has an excellent capacity of anti-corrosion. This anti-rust additive is one of the best raw material choices when preparing ferrous metals or non-ferrous water-based rust inhibitor.
