Fe-Si Oxides (PR101)

Fe-Si Oxides is an inorganic red pigment primarily composed of iron oxide and silica, known for its deep and stable red hue, along with excellent weather resistance, heat resistance, and chemical corrosion resistance. It features a fine and uniformly distributed particle size, offering good opacity and tinting strength, and maintains color stability and durability under UV exposure and various harsh conditions without fading or migrating. Additionally, it is non-toxic and environmentally friendly, making it a high-performance red pigment.
