In response to growing market demand, polymeric technology company, Belzona, now offers a complete leading-edge repair and protection solution. Optimised to be easy-toapply, fast-curing and hardwearing, the combination of Belzona 5711 and Belzona 5721 is specially designed to fortify wind turbine blades with outstanding protection against leading edge erosion for the long term.

New thixotropic paste repair system builds on success of Leading Edge Protection (LEP) coating

From Norway to North Dakota, since its launch in October 2019, Belzona's leading edge protection coating, Belzona 5721, has already been deployed at numerous wind farms worldwide to great success. Lauded as an "extremely fast and cost-effective solution for protecting leading edges" by Jæren Vind Energi AS in Norway, the turbine blade coating provides a quick and straightforward means of protecting leading edges in situ.

Now, building on this knowledge and experience in the field, the Company has developed Belzona 5711 - a thixotropic paste specially designed to be applied in conjunction with the Belzona 5721 protective coating (amongst other product options). This solvent-free, 2part repair paste is specially formulated for the in-situ repair and rebuilding of leading edge erosion and impact damage on wind turbine blades.

New leading edge repair paste facilitates fast turnaround time

Commenting on Belzona's new polymeric solution for the wind industry, Jason Horn, Research and Development Manager, said: "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."
