High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Deqing Demi Pigment Technology Co., Ltd. is a pioneer in compound mineral technologies. We recognize that many clients need a green that is brighter than natural minerals but tougher than organic dyes. Our compound ferric green series is the result of precision engineering, offering the "Best of Both Worlds." We provide the "Dynamic Green" that allows our partners to create visually striking products for construction and industry with the stability they expect from a Demi product.

A: Yes, it is formulated specifically to be alkali-resistant and won't react with cement paste.
A: No, our compound green is processed using "Intimate Blending" technology to ensure the particles stay together in the mix.
We offer "Shade Calibration," allowing us to adjust the green from a "Lime Green" to a "Deep Forest Green" depending on your project needs.
Custom Dispersant Loading: We can pre-treat the compound green to match your specific resin or water-based system for instant wetting.
In Compound Ferric Green, the challenge is "Stokes Law"—different particles settling at different rates. To prevent the yellow and blue components from separating, we utilize "Surface Energy Matching." We coat the particles so they have a similar surface charge (Zeta Potential), which causes them to "Cluster" together naturally in the binder. This scientific approach ensures that the green remains perfectly homogeneous, preventing the "Halo Effect" where one color migrates to the edge of the product during drying or curing.
