Kai Union brand copper and aluminum materials trivalent chromium passivation of Origin: Zhejiang Model: KM0418 Specifications: 25Kg / barrel I. Introduction copper and aluminum materials trivalent chromium passivation solution KM0418, this product consists of a variety of efficient complexing agents, corrosion agent composition. And the general anti-rust oil or sealer is essentially different. After soaking the stainless steel surface in contact with the passivation solution, the aluminum surface micro-chemical reaction, the original chemically active metal surface into chemical nature of the inert metal surface, to the outside material was difficult to produce a chemical reaction. To achieve the effect of long-term rust. Second, the application range ? widely used passivation aluminum, aluminum and aluminum die-casting products, especially for small precision complex parts large passivation. Third, Features and Benefits * passivation time is short, high efficiency; Use low cost, liquid can be reused, implement anti-rust grade material by the time strong, to enhance value-added products, reduce business costs. ? This process has stable performance, surface treatment consistent characteristics. Process by this product after the best available anti-neutral salt spray test 200 hours does not rust; - does not affect the conductive properties of the material does not change the material composition, does not affect the spray, oxidation, and other binding. Fourth, the conventional process treated object - degreasing - over water - passivation - rinse - bubble pure water - drying or dry Note: the process can be adjusted according to the actual situation
