As an example of Henkel's capabilities and commitment to support its customers in Asia, the company recently introduced the first ever Germanischer Lloyd (GL) certified polyurethane blade bonding adhesive, its Macroplast UK 1340 in the region. Based on the different behavior of polyurethane over traditional epoxy based adhesives, manufacturers of wind turbine blades can substantially reduce their energy bill during production, increase productivity and reduce the risk of stress cracking.

Until recently, wind turbine rotor blades have been assembled using epoxy adhesives that require up to 24 hours to cure and generate potentially damaging levels of heat during the curing process. To simplify and accelerate blade manufacturing, Henkel has developed polyurethane adhesive products for the wind power market. Henkel's Macroplast® UK 1340 Series are solvent-free, two-component structural polyurethane adhesives that fully cure in

just eight hours, greatly accelerating the blade assembly process and increasing productivity. The adhesives can be applied at room temperature and undergo a much lower exothermic reaction (less than 100ºC) during the curing process, minimizing the possibility of substrate damage or stress cracking.

 These non-abrasive adhesives offer excellent wetting characteristics and require substantially less surface preparation than epoxies. They will reliably bridge wide gaps - up to 40 mm - between substrates. These GL-certified polyurethanes improve the overall efficiency and reduce the costs of rotor blade production while at the same time improve the reliability of the final product.
