Putty filling of composite components

A perfectly smooth finish with DOPAG putty dispensing systems

In the manufacture of rotor blades, a wide variety of applications are used to make the exterior of the rotor blades stable and efficient. These include edge protection, leading edge protection (LEP) and high-quality surface protection, the gel coat. Although the highest standards of quality are respected during the manufacturing process, small irregularities on the surface of the blade may occur at the end of the production process. These cavities are generally filled so that the surface of the rotor blade finishes with a uniformly smooth structure. Putty material, a filler based on polyurethane with low to medium density, is used for this purpose. The two-component material can be mixed and processed using a DOPAG eldomix metering system.

DOPAG has developed the puttymix especially for the application of putty material. It reliably meters and mixes the material with its high viscosity variance and ensures long-lasting surface protection of the rotor blades.
