Osterholz-Scharmbeck. In rotor blade construction, easy-to-grind fillers are basic products, which are particularly indispensable and must meet high minimum standards. The significance of process-optimized products is increasing also in the service sector, because by choosing a suitable product, users can precisely scale downtime caused by failure and scheduled maintenance intervals. With Bergolin Putty 4D980-4, the Bergolin company presents the latest generation of its popular 2-component putty and thus now also offers a technical solution for use in the service sector.
Like earlier versions, the polyurethane-based liquid putty is particularly suitable for GRP surfaces. Compared to other Bergolin Putty 2-component putties, the development team has optimized all relevant parameters and thus substantially improved process times. For the application process, Bergolin have oriented themselves on the requirements of the technicians on the blade. The name stands for user-friendliness and real progress with a 2-component system technology that can be used in service. The 2-component filler is solvent-free, mixing and application are carried out by machine, so that only the actual filling is done by hand, which significantly speeds up the process.
In terms of performance, Bergolin builds on the well-known strengths of the Putty series and presents an elastic, pigmented and lightfast putty which is tailored for machine processing. At a temperature of 20 degrees Celsius, the pot life is three minutes. Just 30 minutes after application, Bergolin Putty 4D980-4 has hardened sufficiently for immediate sanding and further processing. Due to the greatly reduced drying time, a process reduction of up to 40 percent can be achieved.
Another aspect in the coating of rotor blades are the enormous quantities of material needed due to the physical size of the plants. Accordingly, the yield of a product has an enormous impact on the application process. With a theoretical consumption of 1.35 kg/m² per millimeter of layer thickness, Bergolin Putty 4D480-4 is up to 12 percent more yielding than its predecessor products and thus addresses the increased requirements for coating ever larger rotor surfaces.
