Solar Module Sealants

Solargain® Edge Sealant is a Polyisobutylene Butyl rubber adhesive with integrated desiccant used as an edge seal for thin film and crystalline silicon Photovoltaic modules. It delays moisture ingress, thus helping to protect cells, connections, and transparent conductive oxide coatings from corrosion and degradation. Solargain® Edge Sealant also provides electrical isolation for PV modules. This technology has been successfully used in 1500V modules and meets the component criteria for a cemented joint (UL 1703 Section 42A). This enables active cell area to be placed closer to the edge of glass than without solid insulation.
Solargain products are available in two formats:
Solargain Edge Tape SET
SET is available as a tape produced to dimensions that meet your needs. Tape can be applied manually or with automated application equipment.
Contact us to discuss what size works best.
Pumpable Solargain Edge Tape (PSET)
PSET is  liquid-applied offering the same performance as SET.  It is packaged in 200 liter drums for convenient shipping, unloading, and storage.  It can be used with commonly available dispensing systems and a variety of automated application equipment.
