Application Situation

The customer is looking for a protective coating for their Wind Turbine Blades, to be applied on the leading edge, that has excellent performance, as well and ease of application both in the workshop and in the field throughout the year.

Application Method

The leading edge of the blade has been prepared using hand held sander power tool, removing the existing gel-coat and to provide a clean and rough surface. After cleaning the prepared area, the Belzona 5721 system has been applied as a one-coat system at an average of 500 microns.

Belzona Facts

The Belzona system offers erosion resistance that is equal or better to alternative solutions, while improving the ease of application, saving time and labor costs. The Belzona product can be applied in a wide range of environmental conditions when compared with alternative systems, meaning repair work can take place throughout a greater period of the year, including much of the winter. The wind turbine blade and the Belzona system applied has been put into service at an onshore windfarm, and will be inspected regularly by the maintenance team to monitor performance over time.
