Products:
Belzona® 1311 (Ceramic R Metal)
Belzona® 1321 (Ceramic S Metal)

Belzona was found to be the clear winner when it came to erosion corrosion protection and therefore best value for money. Examined after 3 years no sign of erosion found. No problem seen in achieving required 6 year life. Previous recoating was carried out every 2 years.
