Red Iron Oxide Pigments

Iron Oxides are chemical compounds composed of iron and oxygen. There are sixteen known Iron Oxides and Oxyhydroxides, the best known of which is rust, a form of iron(III) oxide.

Synthetic Iron Oxide is produced from an iron salt (such as copperas) by precipitation or calcination under controlled conditions and is often purer than natural Iron Oxides

Our Red Oxide pigments are Synthetic Iron Oxides that have been Micronised (the process of reducing the average diameter of a solid material's particles by milling or grinding), these synthetically produced inorganic micronised pigments are recognised for their outstanding colour stability, excellent light fastness, weather stability and chemical resistance

Once micronised these pigments fulfill the special requirements needed particularly in the paint industry. Through micronisation, the level of pigment agglomerates is significantly reduced. As a result, these pigment grades exhibit high dispersibility.

The red hues of our inorganic Iron Oxide pigments range from pale, yellowish casts (120 microns) to pure, intense variants and darker, distinctly bluish shades (180 microns). They all offer outstanding quality in terms of tinting, strength and colour consistency

This can also be why many brands use the same pigment number, as they are all chemically identical but look slightly different in hue.
