Product description
This product is the latest energy-saving high-performance environmentally friendly polymer nano coating agent, which does not contain chromium, manganese, nickel, molybdenum and other heavy metal salts, and is free of nitrites, phosphates and volatile components. Normal temperature operation, no sediment and wastewater treatment, no energy consumption, energy saving and environmental protection, short processing time, simple operation, rapid film formation, low treatment cost, widely used in the pre-spraying treatment of various metal surfaces. It is widely used in cold-rolled plates, hot-rolled plates, galvanized plates, aluminum plates, cast iron, carbon steel, aluminum alloys, zinc alloys and other metal materials, especially for powder coating. Appearance: Colorless transparent liquid. Traditional production process: pre-degreasing and degreasing washing surface conditioning
pre-degreasing → degreasing → washing → washing → surface conditioning → phosphating → washing→ washing→drying
