Belzona® 5111 (Ceramic Cladding)

Substrate:

Mild Steel

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflets FBC-2 and FBC-5.

Belzona Facts:

An imitation product had been previously used and only lasted for 10-12 months. The engineers chose Belzona for a more long lasting, cost effective solution for the fan and casing. The fan blades were coated with Belzona® 1391 for outstanding erosion/corrosion protection.
