Product Description stainless iron passivation solution ID4000 Andrew is our own research and development of a new environmentally friendly passivating agent, obtained national patent protection (patent number: 200910260249.5), the product line designed for SUS400 type martensitic stainless steel, in order to improve the corrosion resistance and the development, are universal primary martensitic materials passivation of a new high-quality products. Film density, corrosion resistance, the finished product after processing does not change the color and size, quality leading level in the same industry. Features and Benefits? Liquid can be recycled, per 1kg of drug levels can handle 30 to 50 m2 surface area, effectively reducing the cost 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? The process has stable performance, consistent surface color characteristics. Process by this product after the best available anti-neutral salt spray test 72 hours does not rust? This product is widely used in the passivation GB 1Cr13,2Cr13,3Cr13, SUS416,430, SUS420F other materials, application versatility range? SUS400 series widely used in various national standard and non-standard stainless iron passivation treatment, especially for large complex parts for precision small area passivation, such as screws, axle pin, precision mechanical transmission, communications equipment and other tight Anti-corrosion treatment passivation firmware.
