Iron Oxide Red 190 1309-37-1 CAS Number PVC Coating Pigment Color 01 Model

In the coatings and plastics industries, it serves not only as a colorant that imparts vibrant hues to products but also significantly enhances their weather resistance, chemical resistance, and mechanical strength. Transparent iron oxide, in particular—owing to its exceptional UV-absorbing capabilities—is frequently utilized in automotive paints and high-end wood finishes to protect the paint film and retard the aging process.

In the construction sector, it is extensively employed in the production of materials such as colored cement, floor tiles, wall tiles, and faux marble; here, it serves the dual purpose of providing aesthetic appeal and bolstering the durability of the materials.

In the electronics and metallurgy industries, specific nanoscale synthesis techniques and crystal-structure control methods enable the production of γ-Fe₂O₃ or ferrite materials endowed with superior magnetic properties. These materials are widely utilized in the manufacture of magnetic recording media—such as audio tapes and magnetic cards—as well as soft ferrites.

Superparamagnetic iron oxide nanoparticles (SPIOs), distinguished by their excellent performance in T2-weighted imaging, have been extensively developed as magnetic resonance imaging (MRI) contrast agents for organs such as the liver, spleen, and lymph nodes, thereby assisting clinicians in the early detection of tumors and inflammatory conditions.
