Iron Oxide Red ( S130)

Iron Oxide Red (S130) is an inorganic pigment composed primarily of iron(III) oxide (Fe2O3), presenting as a fine red powder known chemically as Pigment Red 101. This pigment provides strong, stable red coloration suitable for industrial formulations. It is typically supplied in a dry powder form with a pH range of 6.0 to 8.0 in aqueous slurry, ensuring compatibility with a variety of manufacturing processes. This grade is insoluble in water and most organic solvents, enabling long-term color stability in coatings and construction materials. Moisture content is maintained below 1% to prevent agglomeration during storage and handling. Industrial users should note that Iron Oxide Red (S130) resists high temperatures up to firing conditions in ceramics, but should be kept separate from strong acids or alkalis which can affect pigment integrity. Ordering inquiries should specify required batch sizes, as dosage rates typically range from 2% to 10% by weight depending on the application. Proper handling at ambient temperatures and dry storage conditions are recommended to preserve pigment performance and consistency across batches.

In industrial coatings and construction, color durability and resistance to environmental stressors are critical quality determinants. Iron Oxide Red (S130) offers permanent pigmentation that withstands UV exposure, weathering, and high-temperature processes without discoloration or degradation. This reliability supports formulation stability and product lifespan. Using this pigment reduces the need for retreatment or replacement due to color fading, contributing to lower maintenance costs and longer service intervals. The material's insolubility and non-reactivity maintain formulation integrity, minimizing adverse chemical interactions during manufacture or end-use.
