This product is commonly used in industries such as automotive, furniture manufacturing, and general metal fabrication What is Phosphating? Phosphating is a chemical surface treatment process in which a metal surface (usually steel, iron, or aluminum) is coated with a layer of insoluble phosphate crystals by immersing it in a phosphoric acid-based solution. * How It Works: The metal reacts with the phosphating solution. A layer of phosphate crystals (like zinc or iron phosphate) forms on the surface. This layer serves as a protective barrier and/or primer for further coating. #ZNP-54 phosphating Chemicals.
