DOWSIL PV-801
Harmonization Code : 8001.20 | Unwrought tin: Tin alloys
Main features
- Non-Slump PV Frame Sealing
- 746% Elongation for Flexible Sealing
- Glass and Backsheet Junction-Box Bonding
Product Description
DOWSIL PV-801 Neutral Sealant is a one-part, neutral alkoxy-cure silicone adhesive and sealant for photovoltaic module assembly. The non-slump paste can be extruded at a typical rate of 197 g/min through a 3.18 mm nozzle at 0.62 MPa and skins over in about 10 to 15 minutes at room temperature and 50% relative humidity. After seven days under those conditions, the cured sealant has 746% elongation at break, 1.69 MPa tensile strength, and Shore A 28 hardness. Applications include photovoltaic frame sealing and junction-box bonding to glass and plastic backsheets.
Key features
- Non-slump application: Paste consistency supports controlled bead placement for module sealing and bonding.
- High cured elongation: Typical 746% elongation at break provides an elastic cured seal for photovoltaic assemblies.
- PV assembly fit: Used for module frame sealing and junction-box bonding to glass and plastic backsheets.
Applications / Suitable for
- Photovoltaic module frame sealing
- Junction-box bonding to glass
- Junction-box bonding to plastic backsheets
