Photovoltaic modules are exposed to harsh outdoor environments for extended periods. Factors such as UV radiation, high-low temperature cycling, and moisture erosion directly threaten the sealing integrity and power generation efficiency of the modules. The silicone sealants and potting compounds specifically designed for photovoltaic applications, provided by Liyang Kangdawei Industrial Co., Ltd., offer reliable weather resistance, UV aging resistance, and dependable electrical insulation performance. They exhibit strong adhesion to aluminum frames, glass, backsheets, and junction box materials, effectively preventing moisture penetration and extending module service life.
