Iron Oxide Black — CI 77499 / CAS 12227-89-3

Description

1. Product Overview

Iron Oxide Black (CI 77499 / CAS 12227-89-3) is a high-performance inorganic pigment composed primarily of magnetite (Fe₃O₄), widely used for producing deep black coloration, opacity, and durability across industrial applications. It serves as a critical raw material in coatings, construction materials, plastics, inks, ceramics, and specialty pigment formulations due to its excellent chemical stability and weather resistance. With strong tinting strength, UV stability, and cost efficiency, Iron Oxide Black is a strategic pigment choice for manufacturers seeking consistent quality and long-term performance. Its broad industrial adoption makes it an essential material in global colorant and construction supply chains.
