Solar Module Sealants

Solargain® Edge Tape SET LP03 is a Polyisobutylene Butyl rubber adhesive with integrated desiccant used as an edge seal for thin film and crystalline silicon Photovoltaic modules. SET LP03 delays moisture ingress, thus helping to protect cells, connections, and transparent conductive oxide coatings from corrosion and degradation. SET LP03 edge seal 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.
