Introduction of a coordination complex stainless iron complexing agent ID4000A is designed for martensitic stainless iron, in after ID4000 stainless iron passivation solution for the consolidation of the passive film produced and developed separately When using only short-rust effect. Features and Benefits? Stable performance of this product, in the course of just a control to stabilize the PH value of production? The process is simple, requires no special operating environment, non-toxic and low corrosion, general plastic containers can be used, the device is easy to configure? After the product when combined with ID4000 stainless iron passivation solution, which allows the workpiece zero corrosion performance increase of nearly 8 to 20 times, using only a single purpose application for rust? This product is only used by the ID4000 stainless iron passivation workpiece to further improve the performance and use of salt spray corrosion resistance. Use only for inter-process rust when used alone
