      Advantages

      1. Eco-friendly & Non-toxic:Free of heavy metals such as lead and cadmium, chromium exists in stable trivalent form without releasing free harmful substances, compliant with environmental regulations.

      2. Strong Stability:Outstanding light fastness, weather resistance, acid/alkali resistance and solvent resistance; no fading during long-term outdoor use and suitable for high-temperature processing.

      3. Unique Function:As a high infrared reflectance cool pigment, it reflects solar thermal energy and reduces surface temperature, and is suitable for functional needs including energy saving and camouflage.

      4. Wide Compatibility:Uniform particles are easy to disperse, compatible with most polymers, coatings and ink formulations, especially suitable for PVC systems, no bleeding or migration.
