KDW-1536 Neutral RTV Silicone Sealant for Solar Panels - 260°C Temperature Range, 20-30 Year Lifespan
KDW-1536 deketoximized neutral silicone sealant is a high-performance RTV (Room Temperature Vulcanizing) adhesive specifically formulated for solar panel applications. This industrial-grade sealant cures by absorbing atmospheric moisture and provides exceptional bonding strength with CAS 63148-60-7 certification.
- Superior resistance to moisture, dirt, and atmospheric contaminants
- Alleviates mechanical stress from thermal shock and vibration
- Excellent electrical insulation and anticorona performance
- Outstanding outdoor aging resistance with 20-30 year service life
- Stable mechanical and electrical performance from -60°C to 260°C
Specifically designed for solar cell component aluminum frame adhesion and sealing, junction box bonding, and protection of crystalline and polycrystalline silicon from pollution and oxidation.
