Application Method
The application was carried out in accordance with Belzona Know-How System Leaflet MPT-2. After thorough surface preparation, the Belzona 1111 was applied by brush to the repair area. A pre-made split former was positioned over the repair area with a clamp. All excess material was removed and the repair was left to fully cure before removal of the former.
Belzona Facts
The plant operates 5 days a week offering minimal opportunities for maintenance. Replacement of the shaft would have taken at least 3 working days and would have required additional labour and equipment costs, not to mention implications involving health and safety. Belzona was able to offer a repair application over the weekend using under £100 worth of material; saving the client £1000's in equipment replacement costs. This quick response from Belzona ensured there was no loss of production or disruption, allowing the client to continue manufacture on the Monday morning.
2 years on, the shaft is still in service and showing no signs of degradation.
