DuPont Fortasun solar silicones

DuPont Photovoltaic Solutions has announced DuPont Fortasun solar silicones — a product line that features sealants, adhesives, potting agents, encapsulants and electrically conductive adhesives. Used in photovoltaic (PV) applications for over 30 years, the products are designed to increase durability, stability, productivity and overall performance of solar panels.

The product range offers durability in the form of delamination and corrosion protection. It has lasting UV stability, high thermal conductivity formulations and strong adhesive bonds that help reduce failures due to moisture. It is also electrically insulating.

The range’s silicone sealants and adhesives are said to outperform other technologies in frame sealing and junction box adhesion applications by providing protection from moisture, harsh temperatures and vibrations, as well as mechanical and thermal shock. They are designed to endure in the face of extreme climates, helping to reduce the risk of performance deterioration due to environmental elements.

Silicone adhesives are said to outperform typical PV tapes in rail bonding applications, offering adhesion to glass and PV substrates. This added structural strength and durability results in good overall protection and weatherability.

Silicone encapsulants meanwhile protect solar components against corrosion and delamination, prolonging the life of a module while ensuring better power output and improved performance results in terms of increased power generation. Finally, silicone potting agents are suitable for solar industry applications, offering a combination of high performance and durability for photovoltaic junction box applications and beyond.
