Product introduction: The natural color passivating agent for aluminum alloy is composed of organic and inorganic components. The product does not contain chromium, phosphorus and other components. It is suitable for chromium free passivation treatment of aluminum alloy profiles/die cast aluminum alloy surfaces. It can form an inorganic and organic composite film with extremely stable chemical properties in a short time. The film has good corrosion resistance. The neutral salt spray of bare film aluminum profiles is higher than 200 hours, and the adhesion between the film and the coating is extremely strong, The neutral salt spray time after powder coating is more than 1500 hours.
