Nano Calcium Carbonate (Photovoltaic Glue)

product description

• 

• Heat-Resistant & Stable Structure

  USEEN's nano calcium carbonate features a complete cubic crystal structure, nanoscale particle size, and high specific surface area.  Through precise surface treatment with heat-resistant activators and coupling agents, it achieves high compatibility and uniform dispersion in silicone resin systems. This structural design and heat-resistant surface treatment technology provide the material basis for photovoltaic adhesives to maintain stable performance in extreme temperature environments.

• Extreme Temperature Resilience

  This product achieves a balanced combination of high thixotropy, low viscosity, and high extrudability in silicone photovoltaic adhesive systems, significantly enhancing the tensile strength, elongation at break, and long-term heat resistance of the adhesive. Its stable performance without cracking, powdering, or yellowing across a wide temperature range of -45℃ to 350℃, coupled with its ability to maintain strong adhesive strength after UV aging irradiation, ensures ultra-long-term weather resistance and reliability for photovoltaic modules in harsh outdoor environments.
