Product Overview

Iron Oxide Pigments are naturally derived mineral colourants based primarily on iron oxide chemistry, offering excellent colour stability, durability and weather resistance across a wide range of industrial and decorative applications. These pigments are valued for their resistance to ultraviolet exposure, chemical stability and long service life in both internal and external environments.

The range includes Red Ochre P3018|8, a natural red ochre pigment providing warm red to brown tones with good stability for use in coatings, construction materials and decorative applications. Red Iron Oxide MO is a natural red iron oxide pigment with high Feโ‚‚Oโ‚ƒ content, offering strong colour strength, opacity and durability for coatings, plastics and thermoplastics, and construction materials.

Also included is Raw Umber P3560|3, a natural raw umber pigment composed primarily of iron and manganese oxides, delivering deep brown tones with excellent weathering resistance for coatings, mortars and decorative finishes. Raw Sienna P3560|4 is a natural raw sienna pigment based on hydrated iron oxide, producing yellow brown to golden hues suitable for coatings, plasters, mortars and decorative applications.

Together, these iron oxide pigments provide a versatile palette of natural earth tones with consistent performance across multiple formulation systems.
