KDW-1536 Fast Curing Solar Panel Sealant Paste - 310ml/400ml/25KG with 5-30 Minute Tack-Free Time and 260°C Temperature Resistance
KDW-1536 fast-curing deketoximized silicone sealant is a neutral room-temperature vulcanizing adhesive specifically designed for solar panel applications. This electrical bonding and insulation gel provides superior sealing performance with excellent weather resistance.
- Resistance to moisture, dirt and atmospheric contaminants
- Alleviates mechanical stress from thermal shock and vibration
- Excellent electrical insulation and anticorona performance
- Superior outdoor aging resistance with 20-30 year service life
- Stable mechanical and electrical performance from -60°C to 260°C
Specifically engineered for solar cell component aluminum frame adhesion and sealing, junction box bonding, and protection of crystalline and polycrystalline silicon from pollution and oxidation.
