Solar & Photovoltaic Sealants and Adhesives

Solar & Photovoltaic Sealants and AdhesivesThe comprehensive range of products for these new industries is based on PIB, Polyurethane, Silicone and MS Polymer technologies, as well as acrylic and butyl tapes.

The products have been designed to provide the best solution for bonding and sealing Photovoltaic and Solar panels. The focus in panel sealing is the protection of the panel components against ageing and functional loss due to environmental factors. This is done by eliminating the ingress of liquids and gases from the atmosphere.

Liquid application of these systems allows design freedom for the solar panel construction. The elastic properties are a key feature of these products which allow movement and expansion and contraction of the structural components.

A selection of our Solar & Photovoltaic products are shown below:
