New Product Announcement: Wind Turbine Edge Repair

TUESDAY, JUNE 7, 2022


International manufacturer of industrial protective coatings and composites Belzona (Harrogate, North Yorkshire) recently announced via emailed press release the launch of its new edge repair and protection solution for wind turbine blades. The combination of the new Belzona 5711 and Belzona 5721 is reportedly easy to apply, fast-curing and hard-wearing to protect blades from erosion over time.

While the Belzona 5721 protective coating was launched in 2019, the Belzona 5711 thixotropic paste was developed to be applied in conjunction with the product, along with others. The two-part paste is solvent free and formulated for repair and rebuilding of leading edge erosion and impact damage on wind turbine blades.

“Whilst offering rapid cure, Belzona 5711 also has a good working life which allows for the material to be perfectly contoured/formed to the leading edge of the blade. This removes the need for sanding, therefore, eliminating a step in the repair process and simplifying the application,” said Jason Horn, Research and Development Manager.

“Belzona 5711 cures quickly and can be directly overcoated with Belzona 5721 in as little as 30 minutes at 20 C (68 F)—without the need for any additional preparation. At the same temperature, Belzona 5721 will be fully cured within five hours, allowing the turbine to be returned to service in the same day.”

“With the combination of Belzona 5711 and Belzona 5721, the balance between usability and rapid return-to-service makes the products ideal for in-situ repair across a broad application temperature range. The long shelf-life also makes Belzona an ideal stocking material for wind turbine maintenance.”

The repair product has a cure time of 60 minutes in ambient temperatures, is suitable in all climates and has a maximum overcoat window of 24 hours. It can also be applied at offshore or onshore wind farms, with sanding not required prior to overcoating and a three-year shelf life.

Additionally, the company reports that there are reduced health and safety risks, labeled CMR-free in Europe. The cartridge packaging reportedly ensures good mixing quality, ease of use and reduced packaging waste due to higher volume per cartridge.

According to the European Wind Energy Association, the estimated lifespan of a wind turbine is typically 20-25 years, with environmental factors limiting the lifespan. The Belzona products support a circular economic strategy to protect wind turbine blades from this damage and mitigate the industry’s carbon footprint.
