Red Oxide S110
Red Oxide S110 is a synthetic iron oxide pigment known for its consistent reddish-brown color, excellent tinting strength, and superior weather and UV resistance. It is commonly used in paints, construction materials, plastics, ceramics, and inks. With excellent chemical stability, dispersibility, and opacity, Red Oxide S110 is a preferred pigment for both functional and decorative applications. It performs well in both solvent- and water-based systems and is suitable for indoor and outdoor use due to its resistance to fading and corrosion.
Red Oxide S110
Primary Uses
Paints & Coatings
Used in metal primers for anticorrosive protection of steel structures, bridges, and marine vessels.
Incorporated into industrial and protective coatings for equipment, pipes, and machinery.
Used in architectural paints for both residential and commercial projects requiring durable exterior coatings.
Added to powder coatings and automotive coatings for stable red hues and rust-resistant base coats.
Construction Materials
Widely used to color concrete, cement blocks, pavers, and tiles, offering long-lasting, non-fading coloration.
Used in ready-mix concrete, plasters, grouts, and stucco finishes for consistent color throughout.
Provides UV-resistant color for roof tiles, façade elements, and artificial stone products.
Plastics Industry
Utilized in PVC, HDPE, and polypropylene manufacturing to provide deep red coloration in pipes, fittings, and containers.
Offers good color fastness and stability under extrusion and injection molding conditions.
Ceramics & Tiles
Applied in ceramic glazes, terracotta products, and roofing tiles for natural red tones.
Maintains color integrity under high-temperature firing.
Printing Inks
Used in screen printing and packaging inks for coloring on paper, plastic films, and textiles.
Offers excellent opacity and UV resistance for long-lasting prints.
Secondary Uses
Rubber Compounding
Used in colored rubber parts for automotive and industrial use due to chemical resistance and UV durability.
Art Supplies
Incorporated into artist paints, chalks, and pastels as a stable earth pigment.
Preferred in restoration and historic preservation for authentic coloration.
Paper Manufacturing
Used to impart reddish tints in decorative and specialty papers.
Cosmetics (if cosmetic-grade)
In cosmetic-grade form, used in lipsticks, blushes, and foundations for natural red tones. (Only applicable to cosmetic-certified grades.)
Educational & Research
Employed in material science and color formulation studies for pigment stability and dispersion properties.
