2、 Core advantages 
Excellent weather resistance, UV resistance, long-term outdoor exposure without fading or powdering, resistant to atmospheric and polluted gases. 
Resistant to alkali and heat, able to withstand the alkaline environment of cement, not easily discolored during high-temperature processing, suitable for high-temperature processing of plastics and ceramics. 
Good chemical stability, strong inertia, good compatibility with resin, lotion and epoxy system. 
Strong coverage and coloring power, high cost-effectiveness, far lower than organic red pigments. 
Non toxic, non migratory, powder does not leak oil or water. 
3、 Main application fields (matching with titanium dioxide, white carbon black, styrene acrylic lotion, E51 epoxy) 
1. Paint industry: water-based exterior wall emulsion paint (styrene acrylic lotion system), epoxy anticorrosive paint, antirust primer, powder paint, industrial paint coloring, both coloring and antirust effects. 
2. Building materials industry: colored cement, terrazzo, road tiles, concrete coloring. 
3. Rubber and plastic industry: coloring of plastics such as PA66, PP, PVC, etc; Coloring of rubber products, hoses, and sealing strips. 
4. Others: ceramics, papermaking, polishing and grinding materials, magnetic material raw materials.
