Belzona Facts:

Belzona® 4151 was used to repair the damaged top coat on the blades. Belzona® 1341 was used to protect the leading edges and Belzona® 5111 was used to provide overall protection. The Belzona refurbishment has avoided the high cost of blade replace-ment and provided the plant with long term protection of the blades.
