LG303 Stainless Steel Two-in-One Passivation Agent

ItemEnglish Description
Product NameLG303 Stainless Steel Two-in-One Passivation Agent
Product OverviewLG303 Stainless Steel Two-in-One Passivation Agent is an efficient and innovative multi-functional eco-friendly treatment agent, specially designed for austenitic stainless steel (such as 304, 316) and martensitic stainless steel. It scientifically integrates the two functions of acidic degreasing (activation) and chemical passivation in a single process. Through a special formulation system, this product can quickly remove light oil stains, fingerprints and oxides from the surface of stainless steel, while immediately forming a dense and stable passivation film on the surface, significantly enhancing the corrosion resistance (salt spray time) of stainless steel. This product does not contain high-risk substances such as nitric acid, hydrofluoric acid and hexavalent chromium, and is environmentally friendly and highly efficient.

Maintenance & Adjustment1. Control and replenish the alkaline degreaser based on the process parameters (alkalinity index) to ensure consistent cleaning performance.
2. Promptly remove impurities from the bath solution and replenish with fresh solution to restore the process parameters.
3. The bath should be completely renewed every 6 to 12 months. If processing volume increases or the solution becomes turbid and affects performance, an earlier renewal is recommended.
