Application Situation
Wicket gates needing corrosion and abrasion protection
Application Method
Application was carried out in accordance with Belzona Know-How System Leaflet CEP-3. Belzona® 1341 was applied to offer resistance to erosion corrosion. As the leading edges are known to suffer from impact damage due to solids in the water, Belzona® 2121 was applied in two coats (red and black) to offer impact protection in these specific areas.
Belzona Facts
French hydro power stations have been using Belzona for erosion corrosion protection for many years. However, the coating was frequently chipped on the edges due to impact. By applying Belzona® 2121 on the edges, the protection is improved and this technique is now in general use in France. Note Belzona® 2141 is now used in place of Belzona® 2121 due to its easier application characteristics.
