Belzona Facts:

The application of Belzona 1111 restored the original surface profile, allowing the client to avoid the expense of a total part replacement. The Belzona 1341 then added a layer of protection, preventing the recurrence of cavitation or corrosion damage and simultaneously improving flow rates thanks to the smooth surface.
