High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Deqing Demi Pigment Technology Co., Ltd. is a key supplier to the global powder coating industry. We provide high-purity blues that meet the rigorous demands of architectural and appliance finishers. Our pigments are engineered for the "Thin Film" requirements of modern powder lines, ensuring that color consistency is maintained even at thicknesses as low as 60 microns. We are the trusted partner for brands seeking vivid, durable blues for metal furniture, automotive parts, and electronic housings.

A: Our pigments are surface-modified to ensure they do not interfere with the electrostatic charging of the resin particles.
A: Yes, our high-transparency blues are ideal for creating "Candy" or "Metallic" blue effects when used over silver bases.
We offer "Ready-to-Grind" pigment blends, allowing powder manufacturers to skip the pre-mixing stage and go straight to extrusion.
Thermal Profiling: Our lab can perform "Over-bake" tests on your specific resin system to ensure that the blue pigment maintains its ΔE within acceptable limits even during production interruptions.
In powder coatings, color science is linked to "Surface Resistivity." We measure the pigment's impact on the powder's ability to hold a charge. By optimizing the "Ion Content," we ensure the blue particles deposit evenly on the metal substrate. We use CIELab data to monitor the "Hue Angle" (h)—ensuring that the blue remains in the targeted "Royal Blue" or "Cyan" quadrant without drifting toward red or green under high-heat curing conditions.
