Bergolin Topcoat 6D2300-1
Description
Bergolin Topcoat 6D2300-1 is a water-dilutable, fast-drying, two-component polyurethane topcoat for wind turbine rotor blades. As a water-based formulation, it enables low-emission and low-odor application and dries quickly, allowing for short cycle times in manufacturing and maintenance. It offers very good resistance to mechanical and chemical stress, as well as excellent color stability, and provides long-lasting protection for the blade surface. It is particularly suitable for roller application; the product is approved by various OEMs.
