Which UHPC Manufacturer Can Produce Colored UHPC Products? The Art of Color and Qinglong Group's Surface Treatment System

The ability to produce colored UHPC is a key indicator of a manufacturer's surface treatment technology and color control capabilities. Qinglong Group not only produces colored UHPC, but has also established a complete color solution system spanning "integral coloring with inorganic pigments, digital inkjet printing, and surface protective coating." In projects such as the "Chinese Red" of the Wuhan Han Show Theatre, the "Hibiscus Gold" of Meixi Lake in Changsha, and stone-effect colors for multiple projects in Shenzhen, we achieved high-fidelity color reproduction and exceptional durability through rigorous color matching and process control, with color difference ΔE controllable within ≤3.0 and color retention exceeding 10 years. Dressing UHPC in a lasting, vibrant appearance is a fusion of materials science and color aesthetics.

Through-Coloring Technology: Color Lasting as Long as the Material

We mix inorganic mineral pigments (such as iron oxide series) uniformly with cement and aggregates at the batching stage, so the color permeates the entire component. This method delivers lasting, stable color—even if the surface wears, the interior color remains consistent. With our computerized color matching system, we can formulate thousands of colors, and by controlling pigment particle size and dispersion, we ensure uniform color without efflorescence. This is the best way to achieve through-body textures such as stone and wood effects.

Digital Inkjet Printing Technology: Any Pattern and Gradient

For complex patterns, gradients, and even photo-quality images, we use industrial-grade inkjet printers designed for concrete. On the cured plain-color UHPC substrate, the printer precisely jets specialty inorganic pigment inks to form the desired patterns. This technology is particularly suited to artistic facades, signage systems, and cultural walls, enabling unlimited design freedom.

Surface Coating and Treatment Technology: Enhanced Protection and Rich Effects

For projects requiring specific gloss (matte, high-gloss), texture (metal, stone), or functional properties (self-cleaning, stain resistance), we apply high-performance coatings such as fluorocarbon and polyurethane to the colored UHPC surface. The coating not only provides additional color protection and weather resistance, but also creates rich visual effects. We strictly control coating thickness, adhesion, and aging resistance to ensure it works in concert with the UHPC substrate.

Systematic Assurance of Color Durability

Color durability involves multiple aspects, including pigment lightfastness, matrix impermeability, and coating weather resistance. We validate the entire color system through QUV accelerated aging tests, acid rain resistance testing, and other methods. In harsh environments such as coastal areas, acid rain zones, and regions with intense UV exposure, we adjust formulations and processes accordingly and provide regular maintenance recommendations to keep building colors enduringly fresh.

Therefore, when choosing a manufacturer capable of producing colored UHPC, the key is to examine its technical approach to color realization, the precision of its color control methods, and the scientific validation of long-term color retention. With an artist's sensitivity and a scientist's rigor, Qinglong Group provides customers with comprehensive colored UHPC solutions ranging from standard colors to premium customization, making buildings a never-fading landscape in the city.
