Iron Oxide Red
Iron Oxide Red (Fe2O3) is a highly stable, synthetic pigment offering excellent color strength and weather resistance for diverse industrial applications.
Description
Iron Oxide Red (Iron(III) oxide), with CAS number 1309-37-1 and chemical formula Fe2O3, is an inorganic compound widely recognized for its vibrant red hue and exceptional durability. It is a synthetic, high-purity pigment produced through various methods, including the precipitation and calcination of ferrous salts or the thermal decomposition of iron compounds. The specific manufacturing process and particle morphology significantly influence its coloristic properties, including shade (ranging from yellowish-red to bluer-red), tinting strength, opacity, and dispersibility. Fe2O3 is characterized by its outstanding light fastness, thermal stability, and resistance to alkalis, dilute acids, and various environmental factors. Its fine particle size contributes to its excellent hiding power and uniform color distribution in numerous matrices. This pigment is non-toxic and non-migratory, making it suitable for a broad spectrum of applications where color integrity and longevity are paramount.
Applications
Iron Oxide Red finds extensive use across numerous industries due to its robust properties. In the construction sector, it is a primary colorant for concrete, pavers, roofing tiles, and mortars, providing durable and attractive finishes. The coatings industry utilizes it in paints, primers, and protective coatings for architectural, automotive, and industrial applications, offering both aesthetic appeal and corrosion protection. In plastics and rubber, it imparts stable coloration to a wide range of products, including films, pipes, and molded articles. Furthermore, it is employed in ceramics, magnetic materials, and agricultural products. Its non-toxic nature allows for use in cosmetics and certain food packaging materials, though specific grades are required for such applications.
Storage & Handling
Store in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly closed. Avoid generating dust. Use appropriate personal protective equipment during handling. Good industrial hygiene practices should be followed.
