Ferric oxide hydrate

Ferric oxide hydrate (CAS 12259-21-1), commercially recognized as Iron(III) Oxide Monohydrate Yellow, is a synthetic iron oxide pigment that delivers stable yellow coloration across a broad range of industrial substrates. Its hydrated form distinguishes it from anhydrous red iron oxides, making it the preferred choice where warm yellow hues and surface compatibility are required for various manufacturing processes.

In construction materials, it is used to color concrete, cement blocks, and paving products, providing UV-stable, fade-resistant pigmentation that withstands outdoor exposure and harsh weather conditions. Plastics and polymer compounders incorporate it to achieve consistent yellow tones in masterbatches, films, and molded parts without compromising processing stability or the integrity of the final product.

Textile and leather finishers apply it in dyeing and coating formulations where inorganic pigment permanence is required over organic alternatives to ensure long-lasting color and durability. Printing inks and packaging coatings also utilize it for opaque yellow tints in industrial and decorative print applications, offering excellent coverage and high-quality finishes for commercial use.

Ferric oxide hydrate is supplied as a fine dry powder, with particle size and oil absorption values specified to suit pigment-grade applications across the global chemical supply chain. Standard grades include technical and pigment-grade classifications, with quality benchmarked against ISO 11664 color standards common in the coatings and construction sectors for bulk distribution.
