Premiere at the "new energy husum" tesa presents product range for the wind energy sector

(PresseBox) (Hamburg, ) Is adhesive bonding becoming the "key joining technology of the century"? This question, asked by prominent German business newspaper Handelsblatt (September 23, 2009), is one that Andreas Gross, head of the adhesive technology center at the Fraunhofer Institute for Manufacturing Technology and Applied Materials Research (IFAM) in Bremen, answers with a clear "yes." In his opinion, adhesive bonding will eventually supplant conventional technologies such as nails, rivets, screws, and welding.

Premium products on the rise

The best evidence in support of the opinion put forward by Gross, a prominent expert in the field, is the numerous adhesive applications that are already in use today in the booming wind energy sector - and the trend is growing. tesa SE, one of the world's leading producers of selfadhesive product and system solutions for industry, commercial use, and consumers, will appear at the "new energy husum" trade fair (March 18 - 21, 2010), where it will debut its product range aligned specifically to the wind energy sector. The approximately 25 products in the range have various different backing materials and adhesive masses, and all of them help to make processes more efficient and reduce costs. The options for using these products range from production of the giant blades used in wind turbines to protecting materials during transportation and from equipping the nacelles to marking hazardous areas.

Allaround protection thanks to Bodyguard

"Nonproductive" applications include those tapes that are only adhered for a limited time; some of them optimize the manufacturing process, and some of them ensure that the costly equipment retains its value. With tesa® 61122 and 61123, for instance, manufacturing molds can be lined during rotor blade production, making removal of excess resin from surfaces a snap after the blade shells are removed from the molds. That's no easy task, because the molds are often coated with a separating agent that would cause normal masking tapes to fail. And for customers who would prefer not to use a separating agent, tesa offers its fiberglassreinforced tesa® 4810 Teflon tape. The proven tesa® 4657 is already in use today, for tasks including sealing gaps on the nacelle before its installation. Products such as tesa® 50530, which has been known in the automotive industry for years under the name "Bodyguard," offer surface protection for the white blades during assembly, transportation, and storage. Various masking tapes with highly tearresistant paper backings make it easier to paint rotor blades cleanly.

A lifetime spent resisting wind

The "productive" applications include films such as tesa® 54994. Adhered permanently to areas that face extreme strain, such as the windward edges of the gigantic blades, transparent films protect the surface, thereby significantly lengthening maintenance cycles. Rotor blades can be numbered or labeled with codes easily, using tesa® 6930. Plus there are various abrasionresistant and highly durable adhesive tapes that can ensure a nonslip surface on the one hand or permanently mark working areas and hazardous areas on the other. And tesa proves itself as a dependable helper for all "ancillary activities" involving wind turbines as well, for instance with the use of tesa® 4163 for electrical installation and insulation work when finishing the interior of the nacelle.

With its internationally aligned research and development activities, which are conducted at its own laboratories, tesa is able to offer customized product concepts for its customers in the wind energy sector, and will continue to do so into the future. The company's innovation rate of approximately 50 percent serves as ample proof.
