Phosphates play a vital role in paints and coatings as conversion coatings and additives, enhancing adhesion, corrosion resistance, and formulation stability. They are utilized as conversion coatings for metal surface preparation, widely used in automotive, aerospace, and construction industries for components like car bodies, appliances, and structural parts. Besides, phosphates are also used as functional additives in paint formulations, enhancing properties such as corrosion resistance, pigment dispersion, and adhesion, particularly in water-based and industrial coatings.
