Natural Iron Oxide Yellow — Stable, Weather-Resistant Yellow Pigment
Natural iron oxide yellow is a yellow powder pigment, It is made from high quality raw materials. Its main chemical element is Fe2O3, natural iron oxide yellow owns stable quality, high weather ability, good resistance to anti-aging, anti-rust, acid and alkali.
Natural iron oxide yellow pigment is widely used in paints and coatings, construction materials, anti-corrosion coatings, rubber, glasses, magnetic materials etc.

Pre-dispersing with a high-speed dissolver or three-roll milling improves gloss and hiding. Use dispersants suitable for inorganic pigments; test for foaming in solventborne systems.

Natural iron oxide yellow is derived from mineral sources and often has a slightly warmer, earthier hue and lower cost. Synthetic iron oxides can offer tighter batch-to-batch color control and specific particle engineering for high-end applications. We can advise which is best for your application.
We use standard QC checks (hue, tinting strength, particle size) and can provide color variance limits on certificates of analysis. For critical color-matching projects, take advantage of our pre-production sample check.
Yes — custom milling, micronized batches and surface-treated variants are available. Contact technical sales with your target particle size and application, and we'll propose a plan and trial run options.
