Iron Oxide Pigments

Red, yellow, and black iron oxide pigments for paints and construction applications.

Red, yellow, and black pigments for paint and construction use, recovered from iron waste streams rather than mined, which is where our waste-to-value work meets the product catalogue. The three shades are chemically distinct: red is anhydrous ferric oxide, yellow is the hydrated oxide, and black is the mixed-valence magnetite. That matters in service, because the yellow loses its water above roughly 180°C and shifts towards red, so it suits paint and concrete but not a fired application. All three are inorganic, lightfast, and alkali-stable, which is why they hold colour in cement where organic pigments fade. Shades are matched to your reference rather than sold to a fixed swatch.

When you enquire

1. 01Which shade you need, and a colour reference or sample to match against
2. 02The medium it goes into, such as paint, cement, mortar, or plaster
3. 03Loading level, and whether the finished item is fired or heat-cured
4. 04Annual volume, so we can quote against a schedule rather than a single lot
