Introduction Kay League stainless iron passivation solution ID4000 upgrade ID4000-2 belong to the original formula products, the product based on hydroxy acids as the basic subunit, complex organic amine salts and corrosion inhibitor composite made of high quality, with the old version Compared to the product, the product can lead to the exclusion of the red component of the workpiece surface attachments, a clear solution, translucent, passivation film faster, more compact, which can effectively guarantee the passivation process does not destroy the original piece and change color workpiece size, effectively improve the ability of resistance to salt spray stainless steel parts. Features and Benefits? Film speed, only 15-20 minutes to complete the formation of the corrosion film speed? Low acidity, which can meet all kinds of stainless steel iron on the market of non-standard materials passivation, are unlikely to cause discoloration? Relatively Compared to the old products, the ability of this product workpiece corrosion passivation stronger? This product is widely used in the passivation GB 1Cr13,2Cr13,3Cr13, SUS416,430, SUS420F other materials, versatile range of applications? widespread applies to all types of SUS400 series GB 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 fasteners passive anti-corrosion treatment.
