Further improved Productivity in Wind Turbine Blade Repair

TEKNOBLADE® REPAIR 9000 is a single-layer solution to superior wind turbine blade leading edge protection. This wind turbine maintenance coating is an elastomer-based high-solid paint with 100% proportion solids and no VOCs, making it a sustainable solution. The product is applied via application gun or robot and it forms a protective elastic layer of 2-4 mm. It can be used both as a preventive edge protection on new rotor blades as well as for blade repair.


  • Just 1 coat application – repair work is 6 times faster
  • Only a few minutes curing time instead of 2 hours – minimized downtime
  • Processing at temperatures from -8°C up to +50°C – up to 25% more working days per year
  • Protective elastic layer of 2-4 mm – high absorption of impact energy
  • Rain erosion test in accordance with DNVGL-RP-0171: 10 hours at 130 m/s, but at 120 m/s no visual effect even after 21 hours, result after aging according to DNV-GL 0424 is 270 mins
  • Higher productivity, reduced downtimes, more durable

Up to 40% project cost savings in wind turbine blade repair

The erosion of wind turbine blades causes huge repair costs, especially offshore, where repair work is up to 300 times more expensive compared to onshore work. The elastomer-based solvent-free coating technology TEKNOBLADE REPAIR 9000 is a valuable, cost-saving innovation. Compared to blade repair using more traditional technology, the product brings a project cost reduction of up to 40%.

1 layer instead of 3 – a revolution in rotor blade repair

While conventional repair paint systems usually require three coats (primer, filler and topcoat), the time-saving, high-quality paint repair system TEKNOBLADE REPAIR 9000 is capable of repairing damaged edges with just one single coat. This makes repair work up to six times faster.

When good design and good paint work together

“Ever since the beginning of our cooperation with Teknos, we have been enthusiastic about their practical approach, their theoretical knowledge, high level of service and flexibility.”

The Danish company Andresen Towers developed a concept for wind turbine towers that simplifies transport and makes it possible to haul towers everywhere. TEKNODUR COMBI 3560 met the high demands made by Andresen Towers for the surface paint.
