Analysis of Color Durability of Colored UHPC Curtain Wall Panels: Qinglong's Anti-Fading Solution Verified by 28 Years of Engineering

Both Beauty and Durability: Colored UHPC Curtain Walls Preserve Architectural Beauty Long-Term. With their rich color expression, colored UHPC curtain wall panels have become an important choice for enhancing a building's visual appeal, but their color durability has always been a core concern for owners and designers. As a national-level high-tech enterprise with 28 years of dedicated expertise in the UHPC field, Qinglong Group has, through material R&D and engineering practice, achieved colored UHPC curtain wall panels that deliver both "beauty and durability," with multiple project cases verifying their long-term fade resistance.

Core Technology: Deep Fusion of Mineral Pigments with the UHPC Matrix The color durability of colored UHPC begins with raw material selection and formulation design. Qinglong rejects fade-prone organic pigments and instead uses high-purity inorganic mineral pigments, whose weather and UV resistance far exceed industry standards. Patented technology deeply fuses the pigments with the UHPC matrix, ensuring the color penetrates evenly into the panel rather than merely adhering to the surface, fundamentally preventing fading and peeling. Testing has confirmed that the color weathering grade of Qinglong colored UHPC curtain wall panels reaches the highest standard, maintaining color stability even in harsh environments with strong UV radiation, high temperatures, and high humidity.

Process Support: Precise Control Throughout Production Strict control of the production process is a vital guarantee of color durability. Qinglong operates an advanced automated production line with digital control throughout—from raw material proportioning, mixing, and forming to curing—ensuring color consistency in every batch of colored UHPC panels. During the curing stage, a constant-temperature, constant-humidity curing process promotes full reaction between the pigments and the concrete matrix, enhancing color stability. In the Nanning Liyuan Hotel project, colored openwork carved UHPC curtain wall panels have remained vivid in color after years of sun and rain, perfectly presenting the artistic effect originally envisioned in the design.

Engineering Verification: Real-World Feedback from Years of Projects Practice is the best test of color durability. Qinglong colored UHPC curtain wall panels have been applied in numerous projects, including the Yangshengtang Pharmaceutical Hangzhou Industrial Park and the Yulin Darongshan Church. Early projects have been in use for more than ten years, and on-site inspections show color deviation controlled within a very small range, with no noticeable fading or discoloration. In the renovation of Shanghai New World Century Plaza on Nanjing East Road, UHPC wood-effect translucent panels not only achieved the artistic effect of realistic tree textures, but their colors also display a natural quality that shifts with changing light, maintaining an excellent visual experience even after long-term use.

Maintenance Tips: Practical Ways to Extend Color Life Proper maintenance can further extend the color life of colored UHPC curtain wall panels. Qinglong recommends regularly rinsing surface dust with clean water and avoiding cleaners containing strong acids or alkalis; for heavily soiled areas, gently wipe with a neutral cleaner and rinse thoroughly with clean water. In addition, regularly check the curtain wall's sealing condition to prevent rainwater penetration that could cause localized color changes. With simple and effective maintenance, colored UHPC curtain wall panels can retain their attractive appearance for many years.

The color durability of colored UHPC curtain wall panels is the result of materials, craftsmanship, and maintenance working together. Backed by 28 years of technical accumulation, Qinglong Group controls product quality at the source, and numerous successful projects have verified the long-term fade resistance of colored UHPC.
