Hezhen Iron oxide black cement pigment ancient brick dyeing with iron black powder paint with iron oxide

ron oxide black, primarily composed of magnetite (Fe₃O₄) or synthetic iron(II,III) oxide, is a cornerstone pigment in construction, restoration, and protective coatings due to its deep hue, chemical stability, and UV resistance.

In cement-based applications, iron oxide black pigment imparts a uniform, weather-resistant black finish to architectural concretes, pavers, and decorative mortars. Its high tinting strength allows precise color matching, while low solubility ensures longevity in outdoor environments, making it ideal for urban infrastructure and landscape designs.

Descrizione del prodotto

For antique brick staining, iron oxide black powder penetrates porous brick surfaces, creating aged, charcoal-toned finishes that mimic historical masonry. Its alkaline stability prevents color fading when exposed to moisture or pollutants, preserving aesthetic authenticity in restoration projects.

In paint formulations, Fe₃O₄ serves as a durable, opaque pigment for industrial and automotive coatings. Its magnetic properties also enable niche applications in specialty anticorrosive primers and conductive finishes.

With excellent lightfastness, non-toxicity, and compatibility with diverse binders, iron oxide black remains a sustainable choice for achieving deep, lasting blacks across construction and decorative industries.
