DuPont Announces New Fortasun Solar Silicones

DuPont Photovoltaic Solutions (DuPont) has unveiled its new brand of solar silicones, the Fortasun. The American firm unveiled its new product at the 2019 SNEC solar conference being held in Shanghai from June 3, 2019, to June 6, 2019. The new brand will be added to its flagship DuPont Tedlar and Solamet product lines.


The new silicone-based product line features sealants, adhesives, potting agents, encapsulants and electrically conductive adhesives that all deliver the exceptional performance and proven reliability customers expect from DuPont. “These products have been used in photovoltaic (PV) applications for over 30 years, and now they are under a new brand name – Fortasun,” the company stated.

“We are excited to continue to grow our portfolio of solar materials with the introduction of our new silicones line, Fortasun™. It represents quality, reliability and carries the same level of proven performance as our Tedlar and Solamet brands that have been in the field for over 30+ years,” said Dan Barish, Global Business Manager, TCS & Solar Silicones. “Fortasun increases durability, stability, productivity and overall performance of solar panels and helps lower cost per kilowatt-hour and lower long-term cost of ownership.”

The company explained that the durability offered by Fortasun includes delamination and corrosion protection. This helps preserve a level of performance that matches the expectations associated with investments in solar technology. DuPont claims that the product has lasting UV stability, high thermal conductivity formulations, strong adhesive bonds that help reduce failures due to moisture and it’s electrically insulating.

DuPont Fortasun adhesives and sealants are proven to endure in the face of extreme climates, ensuring that energy needs are met in all parts of the world. It also helps reduce the risk of performance deterioration due to environmental elements. Fortasun gives photovoltaic modules and solar concentrators a longer life,” noted Barish. “We believe that materials matter and this is another set we’re bringing to the market to make a difference in how your solar panels perform over their lifetime.”
