High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
At Deqing Demi Pigment Technology Co., Ltd., we provide the raw materials that protect the world's infrastructure. Our powder series for coatings is used by manufacturers who require high-performance color without the complexity of liquid dyes. We understand the rigorous demands of the global coating industry, and our powders are designed to provide a "rugged" performance that withstands industrial wear, chemical spills, and extreme weather.

A: While all heavy minerals can settle, our pigments are surface-treated to promote easy "Re-incorporation" with simple stirring.
A: Yes, they are heat-stable enough for the curing oven and provide excellent charge-stability.
We provide "Sedimentation Analysis," helping you choose the right anti-settling agents to keep our pigments perfectly suspended in your specific liquid coating.
Custom Packaging: For coating manufacturers, we offer "Batch-Scaled" bags that match your specific tank sizes, ensuring zero waste and perfect color every time.
In coating systems, we focus on the "Zeta Potential." By controlling the surface chemistry of the powder, we ensure that the particles repel each other slightly, preventing "Clumping" (Flocculation). This is critical for maintaining "Tinting Strength" and ensuring that the finished coating has a uniform color from the top of the container to the bottom. We monitor the "Specific Surface Area" (BET) to predict exactly how much resin the pigment will "soak up."
