Application Situation

15-year-old limestone filter at a power plant.

Application Method

The client chose to compare three systems simultaneously, over an eight-month period, to assess their performance. The systems selected were: 1. bonding of a rubber lining; 2. using a competitor ceramic coating; 3. using Belzona 1331. The existing rubber lining was removed back to a bare metal substrate before water washing the substrate and blasting to SA 2.5 cleanliness. Subsequently, three coats were applied at 500 microns in accordance with a modified verison of Belzona Know-How System Leaflet TCC-3.

Belzona Facts

The Power Plant’s temporary measure was to repair damaged sections with rubber sheeting until a suitable alternative was found. To ensure the asset remained in service for the foreseeable future, they invited local Contractors to propose solutions. At the end of the trial phase Belzona 1331 passed with no traces of failure. And, as a result, Belzona was awarded the initial job as well as 12 further applications. This was originally prospected in January 2015, with work commencing several months later. Fast forward four years and Belzona 1331 is used to protect all the LSFs and MSFs throughout the site and this application has been adopted by a number of other Power Plants in the region.
