PPG Introduces Revolutionary ‘Thin film’ Wind Turbine Blade Coating System

PPG Commercial Coatings today launched its advanced “thin-film” HSP-7401 Polyurethane Primer and AUE-50000 Series Polyurethane Topcoat wind turbine blade coating system. The coating system is designed specifically for wind turbine blades and uses a thinner build to reduce labor, material use and weight while providing unparalleled adhesion, erosion resistance and flexibility protection properties. PPG technical teams from around the world collaborated in developing the system.

“With the growing international demand for alternative, renewable energy forms, we know how important wind energy is,” said Dave Chapman, PPG global marketing director, commercial coatings. “PPG is extremely active in supporting wind blade manufacturers through the development and application of superior coatings for their products. The HSP-7401 primer and AUE-50000 Series topcoat system sets a new standard for efficiency and will dramatically increase blade protection and durability while also lowering production and life-cycle costs.”

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 topcoat components were specifically designed to work together. Using up to 60% less applied film than conventional polyurethane multi-coat systems, they provide outstanding adhesion and flexibility. HSP-7401 primer delivers outstanding adhesion to the composite substrate, the primary attribute required in wind turbine blade finishing. It is quick-drying and may be topcoated in as little as 30 minutes. AUE-50000 is an extremely erosion-resistant, weather-resilient polyurethane topcoat that offers the smoothness and protection from environmental attack elements required in wind blade applications.

When combined, PPG HSP-7401 and AUE-50000 reduce labor and material costs, extend service life, boost blade energy output and increase overall efficiency. The system is also VOC-compliant to 420 g/l. The two components produce an excellent balance of performance properties that deliver long-term, low-maintenance asset protection in any operating environment including challenging desert and offshore situations.

“Our blade coatings help protect the entire wind energy investment,” adds Chapman. “We’re committed to providing our customers with coatings products that add real, measurable value and will enhance their success.”

PPG has been producing coatings for wind turbine blades for more than 30 years. 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.
