Six times faster repair solution further improved

TEKNOBLADE REPAIR 9000-20 leading edge protection

Paint manufacturer Teknos has launched a new version of their outstanding leading edge repair solution for wind turbine rotor blades. The enhanced white Teknoblade repair 9000-20 shows even better rain erosion test (RET) results according to DNVGL-RP-0171_2018 test standard and is available with an improved system for easy and safe application. The unique one-product, one-layer solution enables six times faster leading edge repair compared to traditional repair systems.

Teknoblade repair 9000-20 is an elastomeric-based high-build coating with 100% solids content. In a single coat it forms a protective, elastic layer with a thickness of up to 2.500 µ, and it cures in a few minutes. The leading edge can be repaired in just one step without additional priming or filling, which delivers a considerable impact on time-savings. While it takes about two days to repair a blade with a traditional system, Teknoblade repair 9000-20 makes it possible to repair three blades in one single day, which is six times faster.

The colourless product version launched in 2018 has already impressed by the long service life of leading edges. Due to its special elasticity, the elastomeric layer can absorb high energies in collision with objects. The resistance of the new white version has been further improved. In rain erosion tests (RET) according to DNVGL-RP-0171_2018, leading edges coated with Teknoblade repair 9000-20 withstand the exposure at 130 m/s speed for more than 10 hours. After accelerated UV-light aging the edges withstand defined impact 270 minutes, longer than required by DNVGL. All in all Teknoblade repair 9000-20 offers considerably increased resistance and enables a longer service compared to conventional coating systems on rotor blades.

Application has been improved, too. Teknoblade repair 9000-20 is applied manually using a battery powered caulking gun and a unique spatula that has been further optimised. The new design ensures the uniformity of the layer thickness and serves as a wind shield during application.  Looking to the near future the simplicity of the application process makes it an ideal product when considering robot applications.
Quality assurance is easy, as the product cures very fast, and both layer thickness and hardness according to Shore A can be measured on site at once. As a solvent-free product containing no volatile organic components (VOC), Teknoblade repair 9000-20 is more sustainable that traditional repair systems and enables safe application with minimal personal protective equipment (PPE) required.

"Leading edge repairs for wind turbines need to be done quickly and easily.  Teknoblade repair acting as both filler and LEP, is a single product solution that provides fast curing, easy and safe application, whilst delivering a long service life", says Clare McDermott, Business Development Director Wind Energy at Teknos. "Our first version met all of these demands however the new white version offers improved durability results against the industry test standards and a simpler and more effective application system. Teknoblade repair 9000-20 is a highly advanced, unique solution with even more convincing benefits for both repair contractors and plant operators."
