The Dow Chemical Company (“Dow”), today announced the launch of the Dow AIRSTONE™ 77-T3 adhesive, an epoxy-based adhesive system used to bond half shells together to create finished wind blade structures. The company said Dow AIRSTONE™ 77-T3 represents a natural evolution in the line of Dow AIRSTONE™ 77 adhesives, which are widely used by fabricators to help meet wind energy industry requirements for stronger and lighter weight wind blades. Dow AIRSTONE™ 77-T3 will be highlighted this week at the China Composites Exhibition in Dow’s booth, A1002-1117, at the Shanghai World Expo and Convention Center. Dow said Dow AIRSTONE™ 77-T3 offers an optimized balance of 30 percent longer open time and 10 percent faster cure rate compared to previous adhesives, for increased fabrication productivity. The company said the new adhesive is also less thixotropic than traditional wind blade adhesives, which makes it easier to control during application and can reduce the need for follow-up rework to modify or reshape cured adhesive along bonded seams. Easier application can also lower defect and scrap rates, resulting in significant cost-savings, Dow said. Dow AIRSTONE™ 77-T3 optimizes wind blade mechanical performance, providing 30 percent greater fracture toughness for increased blade durability. According to Jean Luc Guillaume, Dow Global Business Leader for Wind Energy, Dow AIRSTONE™ 77-T3 is the latest innovation within Dow’s line of AIRSTONE™ Systems™ for Wind Energy. “AIRSTONE™ Systems include adhesives, infusion systems, laminating systems, and mold-building systems,” Guillaume said. “Dow AIRSTONE™ 77-T3 and all of our AIRSTONE™ Systems reflect Dow’s commitment to providing tested and reliable innovation for the wind energy industry. The adhesives technology represented by Dow AIRSTONE™ 77 products continues to provide significant advantages to blade designers, fabricators, and turbine manufacturers, all of whom have a stake in the successful adoption of larger, lighter turbine blades by the wind energy industry.” FORTEGRA™ Epoxy Tougheners VORAFORCE™ Composites System About Dow Dow combines the power of science and technology with the “Human Element” to passionately innovate what is essential to human progress.
