Steodur PUR Putty 4D980
Description
Steodur-PUR Filler 4D980 is a solvent-free, pigmented, elastic, and lightfast 3-component polyurethane liquid plastic (filler) specifically designed for the rotor blades of wind turbines. It is used to fill and level fiberglass-reinforced plastic (FRP) surfaces, can be sanded after a short time, and retains its properties permanently thanks to its elasticity and lightfastness. Curing is controlled by a separate accelerator, the dosage of which flexibly adjusts the processing and sanding times to the ambient temperature. The system, applied using a puttying process, is characterized by high durability and ease of application and is approved by various OEMs.
Recommended use
- Filling and Leveling Surfaces on Wind Turbine Rotor Blades
- Filling work on fiberglass-reinforced plastic (FRP) surfaces (other surfaces available upon request)
- Production of smooth, flat surfaces suitable for sanding as a base for subsequent coatings
- Used in OEM manufacturing and the repair of rotor blades
