Red Iron Oxide – High-Performance Pigment for Industrial & Commercial Application

Red Iron Oxide is the largest volume, most versatile inorganic pigment today with unsurpassed color strength, durability and outstanding chemical stability. Red Iron Oxide is the industry's benchmark standard pigment in paints, construction materials, the ceramic industry, plastics, rubber, coatings and many more applications around the world. Selective Minerals is a leading manufacturer and exporter of Red Iron Oxide in India. The customary long-lasting Red Iron Oxide Colors (Fe₂O₃) from Selective Minerals are produced using the Penniman Process, Calcination Process, Precipitation Process and Laux Process. These processes achieve maximum purity, uniformity and optimum stability. We are the leading suppliers of industrial grades of Red Iron Oxides in India. Selective Minerals tests each batch of Red Iron Oxides to ensure consistency, excellent dispersion, and toughness, to assure our customers that our Red Iron Oxides meet and even exceed their quality product performance expectations. Over a period of time, Selective Minerals is supplying Red Iron Oxide pigments to Paints & coatings, Ceramics, Glass, Construction chemicals, Plastics, Rubber and other industrial applications in India. Selective Minerals has high performing extremely fine pigments with high tinting strength, good dispersion and excellent coloring power for industrial applications. The pigments can also be used in decorative topcoats.

What is Red Iron Oxide?

Red Iron Oxide (Fe₂O₃) is a synthetic or natural inorganic dark red pigment known for its strength of tinting and resistance to weathering, ultraviolet light and heat. These properties make it a long-term industrial pigment used in extreme conditions. Red Iron Oxide is a non-toxic, eco-friendly pigment with optimal physical and chemical properties. With high opacity, tinting strength and soft and vivid colors, Red Iron Oxide has excellent quality, high stability in the alkaline medium and some resistance to weak and dilute acid, lightfastness, weatherability and UV resistance. It is water insoluble and has very good anti-corrosion properties. Red Iron Oxides are some of the most widely used pigments in the world due to their combination of high performance and low cost. Selective Minerals applies special industrial production methods to ensure our Red Iron Oxide is manufactured with very high purity, a uniform particle size, excellent dispersion properties, stability, long shelf life and outstanding resistance to chemicals and weather. This is still the most used pigment in the industry.

Key Features

• Consistent Quality Across Batches: Manufacturing precisely and distributing uniform particle-size means the color performs constantly across different applications.
• Heat & Thermal Stability: High Tinting Strength gives a rich, dark, long-lasting color. This results in lower dosages and costs.
• Extraordinary UV and Weather Resistance: Color lasts for a lifetime, even under harsh sunlight and wet, snowy, or humid conditions of nature.
• Chemical Resistance: It withstands acids, alkalis, and a range of solvents. It suits diverse industrial applications.
• Standards Compliance: Complies with leading global standards for pigments used in paint, rubber and other building materials.
• Excellent Dispersibility: Its particle size makes it easy to incorporate into paints, plastics, coatings, and cement-based products.

Manufacturing Process of Red Iron Oxide

Red Iron Oxide is manufactured by various industrial processes. The high precision methods used by Selective Minerals are outlined below:

• Laux Process: The by-products of the aniline process, black and yellow oxides of iron, can be used to form high quality red iron oxide by calcinating black and yellow iron oxides.
• Calcination Process: Then, Black Iron Oxide is heated turning it into Red Iron Oxide; the color depends on the temperature used during the process, which can produce different degrees of brownish red.
• Penniman Process: Ultra-pure Red Iron Oxide pigments are made from metallic iron reacted in air with acids and have a higher brightness and a stronger tinting strength.
• Precipitation Process: Iron salts are reacted with caustic soda, often in the presence of air. The properties of the pigment depend on pH, temperature, and concentration. This process is the most complicated and gives the purest and most uniform pigments.

Technical Advantages

• Uniform particle size: ensures perfect dispersion.
• Excellent weather, light fastness.
• High tinting strength and opacity.
• Better dispersion with blendability.
