Introduction Kay League stainless iron passivation solution ID4000 only system designed for SUS400 type martensitic stainless iron, in order to improve the corrosion resistance and the development of a new material is martensitic universal primary passivation quality products. This product is environmentally friendly inorganic acid-based oxidants, adding efficient cationic surfactant additives, corrosion inhibitors and a small amount of high quality polymer passivation accelerator compound, does not contain ingredients etching, non-toxic, tasteless, with the current RoHS environmental standards by passivating the product, which can effectively guarantee the passivation process does not destroy the original color of the workpiece, does not change the size of the workpiece, and greatly improve the ability of resistance to salt spray stainless steel parts. Features and Benefits? Without pickling effect, excellent corrosion resistance to effectively prevent the generation of hydrogen embrittlement? 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 with stable performance, surface treatment consistent characteristics. Process by this product after the best available anti-neutral salt spray test 200 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.
