lron Chrome Brown (PBr 29)

Iron Chrome Brown is an inorganic brown pigment composed of iron oxide and chromium oxide, characterized by a deep, stable brown tone with excellent weather resistance, heat resistance, and chemical corrosion resistance. It features a uniform particle distribution and provides outstanding opacity and tinting strength, maintaining color stability under UV exposure and various harsh conditions without fading or migrating. Additionally, it is non-toxic and environmentally friendly.
