Steodur PUR Machine-Application Filler 6D978-5
Description
Steodur PUR Machine Filler 6D978-5 is a solvent-free, elastic, and lightfast two-component polyurethane filler for wind turbine rotor blades. As a thixotropic, lightweight filler with a mixed density of approximately 1.15 g/cm³, it levels out surface irregularities and creates a smooth, flexible, and lightfast base for further coating. It is applied using a two-component dispensing system; since no air is incorporated during the application process, no open pores remain after sanding.
Recommended use
- Machine-Applied Coating of Wind Turbine Rotor Blades
- Leveling surface irregularities on fiberglass-reinforced plastic (FRP) components (other substrates available upon request)
- Creating a smooth, elastic, and lightfast base for subsequent coatings
- Mass production using 2K dispensing systems with an extended processing time of approximately 4 minutes

Advantages at a glance
- Lightweight filler with a density of approximately 1.15 g/cm³ – weight-optimized construction on the rotor blade
- Solvent-free – low-emission application with approximately 10 g/l VOC
- Elastic and lightfast—a permanently stable base for rotor blade coatings
- Thixotropic – stays in place even on vertical surfaces
- Working time of about 4 minutes—more flexibility for larger surfaces
- No open pores after sanding thanks to air-free system processing
- Mixing errors are made visible and can be prevented by the black hardener
