Iron Oxide Pigment
Iron Oxide Pigments are versatile, inorganic colorants valued for their excellent durability, heat stability, and non-toxicity. Available in yellow, red, black, and brown shades, they are widely used in construction (colored concrete, paving stones, roofing tiles), coatings, plastics, and ceramics. These pigments provide consistent coloration, superior UV resistance, and enhance the longevity of finished products.
