BASF Demonstrates Innovations for High-performance Wind Power in Asia    

By Tian Lijun     

BASF demonstrated how the latest innovations from the chemical industry can provide better performance for wind turbines, at Wind Power Asia in Beijing on July 8-10, 2009.
   BASF offers state-of-the-art epoxy systems. With BASF's Baxxodur two-component systems, based on epoxy resins and curing agents, the production output of large rotor blades can be significantly increased. To assure that the forms for blades are filled completely and rapidly, the BASF systems react slowly at the initial stage. Subsequent heat application speeds the curing process and releases the form for production of the next blade more quickly. Consequently, cycle times for the manufacture of rotor blades can be reduced by up to 30%, thus raising productivity.  Because the new systems are processed additionally in a broader temperature range than conventional products, the production process becomes more flexible.
   BASF's RELIUS brand offers leading coating technologies for the protection of rotor blades. BASF was the first company worldwide to develop coatings specifically to protect fiberglass and epoxy systems for wind turbine blades. RELIUS coatings solutions are characterized by high weather (UV) resistance, flexibility and abrasion resistance. The system comprises gel coats, primers, special edge protection products and topcoats. Offering comprehensive service and training as well as versatile application methods including both rolling and spraying, RELIUS coating solutions help to reduce costs in the manufacturing process. Through their high-performance, two-component polyurethane chemistry, the products are solvent-free and make a significant contribution to global renewable energy.
