6 TIMES FASTER REPAIR SOLUTION FOR ROTOR BLADE REPAIR

TEKNOBLADE REPAIR 9000 is a solvent-free coating with 100% proportion of solids and no VOCs. It can be applied with a coat thickness of between 2000 μm - 3000 μm (2-3 mm) and it forms a protective elastic layer. The product can be used both for a preventive leading edge protection (LEP) on new rotor blades and for rotor blade repair. While a 3-coat system is required in conventional systems, TEKNOBLADE REPAIR 9000 is capable of repairing damaged edges with just one single coat. And the edge protection withstands exposure for even longer. A true revolution in rotor blade repair!
