Steodur-PUR filler 4D980

The Steodur PUR filler 4D980 is a solvent-free, pigmented, elastic and lightfast 3-component liquid plastic that was specially developed for the rotor blades of wind turbines. The product impresses with its high elasticity, excellent adhesive strength and long durability. It is easy to process and provides an even, smooth surface with very good resistance to weathering. By adding Steodur-PUR accelerator 6D972-0000, the drying time can be significantly reduced, allowing flexible adaptation to different ambient temperatures.

• Filling work on GRP and composite surfaces, especially on rotor blades
• Application at temperatures from +8 °C to +30 °C
