Natural earth-derived iron-manganese oxide pigment with consistent warm brown hue and excellent lightfastness.
High tinting strength and good dispersion stability in both aqueous and solvent-based systems.
Non-toxic, heavy metal-free formulation compliant with EN 71-3 and ASTM F963 safety standards.
Thermally stable up to 300°C, suitable for medium-temperature industrial coating and plastic processing.
Low oil absorption (18–22 g/100g) enabling high loading capacity without compromising viscosity or film integrity.
Architectural and industrial waterborne and solventborne coatings (e.g., primers, masonry paints, anti-corrosive finishes).
Polyolefin, PVC, and engineering thermoplastic coloration for outdoor profiles, pipes, and construction components.
Cementitious systems including concrete admixtures, tile grouts, and decorative stucco finishes.
Artist-grade acrylics, oils, and dry media requiring archival stability and natural earth pigment authenticity.
Industrial inks for packaging, labeling, and security printing where UV resistance and chemical inertness are critical.
