1527 Silicone Sealant is a high-quality, one-component adhesive based on silicone polymer that cures by reaction with moisture to form an elastic seal. It is designed for sealing the side frames of solar cells and solar energy lamps. The sealant offers excellent UV resistance, thermal performance, and durability in insulation, thermal cycling, and damp/freezing conditions. It is UL certified and provides long-lasting protection against environmental stresses.
Recommended uses include:
Sealing side frames of solar cells
Sealing solar energy lamps
General sealing and adhesive applications in photovoltaic modules exposed to heat, moisture, rain, and hail
