Belzona Facts:

Belzona® 1341 (Supermetalglide) was used to hold the blast, and formers were used to rebuild the vanes. The entire wheel was rebuilt with Belzona® 1311 (Ceramic R-Metal) and overcoated with Belzona® 1321 (Ceramic S-Metal). The application saved the operation of the plant since a replacement wheel was no longer available.
