Metal surface treatment chemicals are chemicals used to prepare the surface of the metal for paint or coating. They are water and solvent-based chemicals used to increase the resistance of the surface after the metal cleaning process and to ensure better adhesion of the paint and coating to the surface. Metal surface treatment chemicals include many chemicals suitable for the process such as alkaline degreasing, acidic degreasing, ultrasonic washing, phosphate coating, iron phosphate coating, zinc phosphate coating, manganese phosphate coating, passivation, activation, rust and canvas removal, protective zinc phosphate coating, zinc phosphate coating before painting, aluminum coating, chromating, metal treatment liquids to increase the resistance of the metal.
