Belzona Facts
Thanks to the Belzona products, the filter was back in service after a rapid, easy and in situ repair. The cost of replacing ebonite would have been much higher. Belzona enabled a quick in-situ repair to be carried out, ensuring filter could returned to service with minimum disruption to production. Alternative (replacing ebonite) would have taken far longer and at far higher cost
