SolarGain® Solar Panel Sealants

SolarGain® Edge Sealant is a desiccated butyl/desiccated polyisobutylene (PIB) solar panel sealant designed for use in a wide variety of photovoltaic (PV) modules. Trusted by PV module manufacturers for more than 20 years, this solar edge seal tape protects cells, connections and transparent conductive oxide coatings from moisture ingress, helping improve panel longevity and maximize power.

SolarGain Edge Sealant (SET LP03) is designed for long-term outdoor performance with high-heat stability and excellent UV resistance. The desiccated PIB enables protection for more than 25 years. The product retains adhesion after exposure when tested under extreme UV conditions (A5 for 2000 hours) per IEC 62788-7-2. Modules utilizing SET LP03 are ready for field performance wherever deployed.

SolarGain Edge Sealant also provides electrical isolation for PV modules. This solar cell sealant technology has been successfully used in 1500V modules and meets the component criteria for a cemented joint (IEC 61730-1 Ed. 2). This enables the active cell area to be placed closer to the edge of glass than without solid insulation.

SolarGain Edge Sealant is available in two packaging formats:

Pumpable SolarGain Edge Tape (PSET)
PSET is hot-melt liquid-applied and is ideal for high-volume production. It is packaged in 200-liter drums convenient for production efficiency with little downtime and minimal waste. It can be used with globally available dispensing systems and a variety of automated application equipment.

SolarGain Edge Tape (SET)
SET is a solar edge sealant, pre-extruded to tape dimensions specific to your module design needs. Tape packages are easier to handle and scalable from intermittent use to high-volume automation.
