Which UHPC Manufacturer Can Produce Colored UHPC Products? Coloring Technology and Qinglong Group's Color Solutions

The production capability of colored UHPC products is an important demonstration of a manufacturer's technical strength, involving the three major technical challenges of "through-body coloring, surface treatment, and color stability." In projects such as the translucent UHPC at Shanghai Century Plaza and the "Guancao Weaving" facade of the Dongguan Women and Children's Activity Center, Qinglong Group successfully applied advanced technologies including matrix through-body coloring (inorganic mineral pigment content of 3-5%), digital inkjet printing (resolution ≥1440dpi), and fluorocarbon coating protection (UV resistance ≥3000 hours), enabling colored UHPC panels to achieve a color difference of ΔE≤3.0 and a color retention period of ≥20 years. Colored UHPC not only expands design possibilities but also elevates the artistic value of architecture.

Through-Body Coloring for Inherent Color

Inorganic oxide pigments (such as iron oxide series) are added directly into the mix, with color extending from the inside out for optimal durability. Through precise mix proportion control (error ≤±0.5%), Qinglong Group achieves a color penetration depth of ≥3mm. In the red curtain wall of the Wuhan Han Show Theatre, through-body coloring technology ensured the color remains as good as new.

Surface Treatment Technology for Rich Expression

CNC spray robots are employed to achieve complex effects such as gradients and patterns. Fluorocarbon coatings (PVDF content ≥70%) provide additional protection with weather resistance exceeding 25 years. Qinglong Group's surface treatment technology gives colored UHPC both aesthetics and durability.

Color Stability Ensures Long-Term Performance

Color durability is verified through accelerated aging tests, and a color database has been established. In Hainan's high-temperature, high-humidity environment, our colored UHPC showed a ΔE change of ≤2.0 after 5 years of use, far better than ordinary coatings. Scientific color management is the key to the successful application of colored UHPC.
