Silicone Sealants for LED Lights & Lighting Applications
Redisil silicone sealants provide flexible sealing solutions for suitable LED lighting housings, covers, electrical enclosures, outdoor luminaires and lighting assemblies.
LED lighting products may operate under heat, moisture, vibration, dust, UV exposure and changing environmental conditions. Suitable silicone sealants can help provide environmental protection while maintaining a flexible seal around compatible components and housings.
Silicone Sealing Solutions for LED Lighting
LED lighting systems require protection from environmental exposure while also managing heat, vibration and thermal movement during service.
Silicone sealants are suitable for a range of non-structural LED lighting sealing applications where flexibility, weather resistance and environmental protection are required.
Depending on the design, silicone can be used around suitable LED housings, covers, cable-entry areas, electrical enclosures and outdoor lighting interfaces.
Redisil focuses specifically on silicone-based sealing solutions. For application-specific LED silicone technologies, the wider Fasto Silicone Compounds portfolio can also be evaluated.
