High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Deqing Demi Pigment Technology Co., Ltd. is a global leader in construction-grade pigmentation. We understand that in the building industry, the pigment is a structural component as much as a decorative one. Our construction series is manufactured to the highest standards of purity and consistency. We provide the "Elemental Color" that allows designers to move beyond grey concrete, creating warm, vibrant, and sustainable urban environments that resist the ravages of time and weather.

A: No. Once the concrete is cured, the pigment is an integral part of the stone-like matrix and is completely insoluble.
A: Yes. Grey cement produces earthy tones, while white cement allows for bright, pastel, or vivid colors.
We offer "Job-Site Color Consulting," helping you determine the exact pigment dosage needed based on your local aggregates and sand color.
Pre-Measured Batch Bags: We can provide custom-weight water-soluble bags that can be thrown directly into the mixer, ensuring perfect dosing and no mess.
In concrete construction, the "Hydration Process" creates a highly alkaline environment (pH>12). Most organic dyes would be instantly destroyed. Our oxide pigments are "Inorganic Minerals" that are chemically inert at high pH. We manage the "Particle Size Distribution" to ensure that the pigment particles are smaller than the cement grains, allowing them to fill the interstitial spaces and coat the cement paste effectively. This scientific approach ensures maximum "Color Saturation" without disrupting the delicate crystal growth of the calcium-silicate-hydrate (CSH) bonds.
