AD RR -201 is widely used across various industries for metal surface pre-treatment before painting and powder coating. It is extensively applied in automotive component manufacturing, steel fabrication units, engineering industries, fastener production, pipe and tube manufacturing, electrical panel fabrication, metal furniture production, and white goods manufacturing such as refrigerators and washing machines. The product is also commonly used in powder coating plants and general metal finishing operations where enhanced corrosion resistance, improved coating adhesion, and long-term surface protection are required. By forming a uniform phosphate layer on metal surfaces, AD RR -201 helps improve product quality, durability, and overall coating performance.
