BJ-HP1-1W high diffuse reflective coating is 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.
Usage
1. Before using this product, please fully stir (30min) it well; the amount of medium should be added according to the recommendation of our technical personnel. The high addition of medium will affect the shading performance (add the
professional medium according to the actual situation on site, and consult our technical personnel).
2. Keep the workplace clean to avoid floating dust adsorbed on the ink surface. In addition, please keep the air unblocked
and avoid high temperature, high temperature and high humidity.
3. After using, please immediately seal the cover and place it under 18 ~ 25 ° C (normal temperature, dry); avoid mixing
sand dust, dust and metal powder into the slurry; please fully mix before use again.
