DuPont Announces New DuPont™ Fortasun™ Solar Silicones


The Dow Corning Silicone line is now Fortasun™ and joins the DuPont materials portfolio with over 30+ years proven field performance to boost customer LCOE

SHANGHAI: At the 2019 SNEC solar conference today in Shanghai, DuPont Photovoltaic Solutions (DuPont) announced they added a new brand to its flagship DuPont™ Tedlar® and Solamet® product lines, DuPont™ Fortasun™ solar silicones (VIDEO).

“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.”Built on decades of experience from Dow Corning, 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 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. Fortasun™ 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,” notes 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.”

Products included under the Fortasun™ brand:

Sealants and adhesives

Silicone sealants and adhesives outperform other technologies in frame sealing and junction box adhesion applications by providing protection from moisture, harsh temperatures, vibrations, as well as mechanical and thermal shock.

Potting agents

Silicone potting agents possess unique properties and benefits that make them ideal for solar industry applications. They offer a unique combination of reliable performance and durability for photovoltaic junction box applications and beyond.


Silicone encapsulants 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.

Rail Bonding

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