Iron Oxide Yellow (Pigment Yellow 42 / FeOOH)
Synthetic Iron Oxide Yellow (Pigment Yellow 42, alpha-FeOOH goethite) is a robust inorganic yellow pigment produced by the controlled precipitation and oxidation of ferrous salts, offering excellent lightfastness, acid and alkali resistance, and non-toxicity at competitive pricing. It is the most widely used yellow inorganic pigment in construction materials, architectural coatings, and concrete coloring. Chemzip supplies iron oxide yellow in standard, fine, and transparent grades.
