产品详情

Solar glass enamel is high diffuse reflective coating, a water-based high reflective glass glaze applied to the back panel of photovoltaic double glass modules, which is printed onto the glass surface through screen printing and tempered at 650-730 ℃ before melting into the glass, achieving color adhesion and durability.

The coating can effectively improve the power generation efficiency of solar cell modules; Excellent PID resistance, no blackening under 192h dual 85 testing conditions, power attenuation ≤ 1%; The coating has excellent aging resistance and mechanical properties, and can adapt to various outdoor environments. This product has passed various performance testing certifications from the National Photovoltaic Testing Center, and has obtained certifications such as SGS environmental protection certification, RoHS, REACH, and VOCs. The modified product is environmentally friendly and pollution-free, with superior comprehensive performance.
