Bergolin Putty 4D9700-LowTemp

Bergolin Putty 4D9700-LowTemp is a solvent-free, pigmented and elastic 2-component liquid plastic specially developed for the rotor blades of wind turbines. The material offers high light resistance, flexibility and adhesion even at low temperatures. It is ideal for processing in cooler environments without compromising on quality or curing. Its thixotropic consistency makes it ideal for filling and ensures a smooth, resilient surface - perfect for the fast, precise and weather-independent maintenance of GRP components.
