Ситуация с приложением

Leading Edge Protection solutions need higher temperatures to properly be applied and cured. As temperatures dropped towards 40°F (4.4°C) there are not many solutions out there which will work.

Способ применения

The application was carried out in accordance with a modified version of Belzona Know-How System Leaflet FBC-1. The blades were coated on the turbine at the operation site. The pitting and loss of surface on the leading edge was resurfaced with a filler product and rebuilt to dimensions. The surface area was sanded down with a mechanical sander and cleaned with a rag and non-residual solvent cleaner. One coat of Belzona 5721 at 20 mils (508µm) was applied.

Белзона Факты

The work was completed by the contractor thanks to Belzona 5721 as they could not normally apply LEP coatings on the blades at this time of the year. It saved the customer time as the coating cures in 6 hours, therefore downtime was substantially reduced.
