Bergolin Putty 4D9700-HighTemp

Bergolin Putty 4D9700-HighTemp is a solvent-free, pigmented and elastic 2-component liquid plastic that has been specially developed for wind turbine rotor blades. The material impresses with its high light resistance and excellent mechanical properties. It enables a durable, weather and temperature-resistant surface repair that adheres reliably even under extreme environmental conditions. Thanks to its thixotropic consistency, the product can be optimally filled and ensures precise, even results - ideal for the fast and professional maintenance of GRP structures in outdoor areas.
