White Solar Panel Silicone Sealant KDW-1536 Neutral Cure Adhesive with 260°C Temperature Resistance and 20-30 Year Lifespan
KDW-1536 deketoximized silicone sealant is a neutral cure silicone adhesive specifically formulated for solar panel applications. This white sealant cures at room temperature by absorbing moisture from the air, providing excellent adhesion and sealing performance for various solar component materials.
- Resistance to moisture, dirt and atmospheric components
- 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
