Undercoating Pigment Zinc Phosphate Used In Paint
Iron phosphate is a lightweight amorphous coating. It generally has a coating weight between 15-100 mg/ft2 and typically used as paint base for low-corrosion environments.
A modified Zinc Phosphate Coating is a medium weight crystalline phosphate coating. It has a coating weight between 150-350 mg/ft2. It is typically used as paint base for high-corrosion environments.
A heavy zinc phosphate coating produces a very heavy coating weight, typically between 700-3,500 mg/ft2. It is used for unpainted applications.
