Nano-coated blades could delay ice formation

A U.S. turbine OEM has presented encouraging research on nanotextured aniticing surfaces. These surfaces reduce ice adhesion as well as delay the onset of ice formation in simulated icing conditions. The team, from GE Global Research, was inspired by studies of the Lotus plant, which revealed a nano-textured wax on its leaf surfaces that repels

Graphene shows promise as thin anti-corrosion coating

Research now shows that graphene is the thinnest coating for protecting metals against corrosion. A study on this potential new use of graphene appears in ACS Nano, in which researchers say they’re finding new ways to slow or prevent corrosion on metals, such as those used with windpower technology. One approach to prevent corrosion involves

Sealants and adhesives for base, tower and nacelle

A manufacturer of adhesives and sealants also provides lubricants and coatings for installation and maintenance of blades, nacelles, towers, and bases. For rotor blade repair, Loctite polyurethane resins cure rapidly at room temperature, reducing downtime associated with blade maintenance. In the nacelle, the company’s products provide UV/moisture resistance to seal against harsh weather. Cleaners and

2012: Trends in coatings

Coatings in the windpower industry fall into at least three categories: Those applied to fasteners, those for blades, and others. Owner demands for increased reliability are driving trends in each. The results have been a wider variety and more specialized of coatings for other components. Coatings on bolts These are getting more attention, especially as

Materials: A growing wind industry demands more durable coatings

With total installed capacity reaching 250 GW at the end of 2011, wind is the most prevalent source of renewable energy today. Furthermore, increasingly strict renewable portfolio standard programs–33% by 2020 in California, 20% in Europe, and 15% in China–provide significant impetus for the wind industry. However, the proliferation of effective wind installations heavily hinges

Coating developer wins best-practices award

Hempel’s accomplishments in the protective-coatings market for wind turbines have won the company the 2011 Frost & Sullivan Product Line Strategy Award. Business research and consulting firm  Frost & Sullivan’s Best Practices Award recognises outstanding achievement and superior performance in areas such as leadership, technological innovation, customer service and strategic product development. Hempel says that
