Iron Oxide Yellow — CI 77492 / CAS 51274-00-1

Description

1. Product Overview

Iron Oxide Yellow (CI 77492 / CAS 51274-00-1) is a high-performance inorganic pigment composed primarily of hydrated iron oxide, widely recognized for its excellent color stability, opacity, and durability. It is extensively used across construction materials, coatings, plastics, ceramics, cosmetics, and industrial pigment applications where consistent yellow coloration and long-term performance are required. Its superior weather resistance, chemical stability, and cost efficiency make it a preferred choice for manufacturers seeking reliable mineral-based coloring solutions. As global industries increasingly prioritize durable and environmentally stable pigments, Iron Oxide Yellow remains a strategically important raw material in the international pigment supply chain.
