KDW-1536 RTV Silicone Rubber Adhesive Sealant for Solar Panels - 260°C Temperature Resistance, 20-30 Year Lifespan
KDW-1536 deketoximized RTV silicone rubber adhesive sealant is a neutral curing sealant designed specifically for solar panel applications. This high-performance material provides excellent moisture proofing, electrical insulation, and long-term durability for solar energy systems.
- Excellent resistance to moisture, dirt, and atmospheric components
- Alleviates mechanical stress and tension from thermal shock and vibration
- Superior 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
- Strong bonding to most materials including aluminum frames and junction boxes

Thoroughly clean the surface of adherend or coated object, removing rust, dirt, and greasy contaminants.
Cut the head of plastic pipe, attach long nose applicator, and extrude adhesive onto clean surface. Fix adherend in position.
Place adhesive units in air for curing. Product becomes usable after 24 hours at room temperature.
Seal and store remaining sealant immediately after use. Remove crust from head when reusing - this does not affect performance.
