Coating company winds award for low-solvent material

The Ultra-High Solids and Speed system (UHSS), a two-coat protective paint system for onshore wind turbines produced by coatings manufacturer Hempel, was granted a patent from the European Patent Office. UHSS uses two high-solids coatings to reduce volatile organic compounds (VOC) emissions by up to 70% compared to standard three-coat systems, depending on the system.

Company expands line of protective sprayers

A company has added several multi-component protective sprayers to its line. Graco says its XP Sprayers provide on-ratio precision for fast-curing materials and a quick return on investment for contractors who switch from hand mixing. Displacement pumps proportion materials, which are then mixed at the manifold. “The beauty of these sprayers is that they eliminate

Solvent-free coating for offshore turbines

A coatings manufacturer has released Hempadur Multi-Strength 35460, a solvent-free version of its protective coating for offshore wind turbine foundations. The coating has a six-hour drying time and is gentler on the environment. Hempel’s new solvent belongs to the 45753 product line, which has been used on more than 20 wind farms, including Walney Offshore Wind

Research group releases top 10 companies for Q3 2012

Potentially disruptive technologies for efficient grid storage, low-cost solar, drug delivery, cheaper LEDs, and novel graphene materials highlight Lux Research’s Q3 list. Technology research firm Lux Research profiled 370 companies across 15 different emerging technology domains in the third quarter of 2012 as part of its ongoing Intelligence services.  Drawing on the domain expertise of

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
