PPG Commercial Coatings Increases Role with Wind Turbine Blades

The coating system is designed specifically for wind turbine blades and uses a thinner build to reduce labor, material use and weight while providing adhesion, erosion resistance and flexibility protection properties, according to the company. PPG technical teams from around the world collaborated in developing the system.

The PPG HSP-7401/AUE-50000 series system was developed through extensive global testing against a wide range of blade-coating standards and specifications. The polyurethane primer and top-coat components were specifically designed to work together.

Using up to 60% less applied film than conventional polyurethane multi-coat systems, they provide improved adhesion and flexibility, says PPG. HSP-7401 primer is quick-drying and may be top-coated in as little as 30 minutes. 

 PPG Commercial Coatings has dramatically increased its involvement in the global wind turbine industry. With the growing international demand for wind power, PPG is assisting OEMs with the development and application of advanced coatings and materials for wind turbine blades. Understanding the process of harnessing and delivering wind energy as well as the harsh conditions in which wind turbines must operate, has enabled PPG to develop coatings solutions for this rapidly growing industry.

PPG is not a newcomer to the wind energy industry. The company has been producing coatings and fiber glass for wind turbine blades collectively for over 30 years and has intensified its focus in the last 24 months. PPG is heavily involved in research and development that will help enable OEMs to produce larger and more powerful turbines that compete with traditional forms of energy generation.

“We know how important this form of renewable energy is. We’ve added resources, enhanced our expertise and are developing innovative products for Europe, Asia and North America. We’re helping our OEM customers with products that take cost out of their process, increase turbine energy output and improve overall turbine durability. With our broad geographic footprint, we can support this emerging industry on a global basis,” said Dave Chapman, PPG global marketing director, commercial coatings.

Experts from the commercial coatings group work with PPG’s protective and marine coatings and fiber glass divisions to address OEM needs for strong, durable and element-resistant wind energy components. The groups supply advanced protective coatings for turbine blades and towers as well as fiber glass for the composite blades. PPG proprietary wind energy products include:

* Selemix polyurethane coatings and primers for extended life and improved performance of turbine blades.
* PSX® and Amershield™ protective and marine coatings that combine aesthetic appeal with exceptional corrosion and weather resistance onshore and offshore.
* Hybon® 2002 and 2026 fiber glass roving which allow for a better bond between fiber glass and resin for stronger turbine blades.

According to Cheryl Richards, PPG global market development manager and leader of PPG’s cross-business wind energy team, the number of wind turbine installations around the world is expected to more than double by 2012.

The marketplace has recognized PPG’s competency. “Part of our mission is to develop long-life coatings that protect wind energy assets, and we’ve seen a significant increase in our coatings and fiber glass sales over the past year. That higher interest is evident in shows we’ve participated in this year in Brussels, Beijing and Houston,” says Richards.

PPG is continuing to develop coatings to protect tower and turbine components for longer periods of time through the most extreme conditions along with coatings that de-ice and de-bug turbine blades.

“Our blade coatings help protect the entire investment,” adds Chapman. “We’re committed to helping OEMs do exactly that.”

Pittsburgh-based PPG is a global supplier of paints, coatings, chemicals, optical products, specialty materials, glass and fiber glass.
