Used as a corrosion-inhibiting pigment in coatings and primers, especially in industrial paints for steel and metal structures. Provides long-term protection against rust and oxidation without toxic effects, making it suitable for environmentally friendly paint formulations. Also applied in plastics and polymers to enhance thermal stability and reduce flammability. Commonly found in anti-corrosive primers for bridges, pipelines, and marine environments due to its excellent water resistance and durability.
