Belzona 2111 was applied directly over the bonded plate repair to restore the rubber lining.
Belzona Facts
The paper mill undergoing a planned outage for routine repairs included this repair of a leaking outlet from the demineralization tank. A compacted time frame necessitated the use of several materials to repair the leakage prior to start up. The customer was satisfied with the ability to apply Belzona 2111 directly over Belzona 1221 that enabled the job to be done without cure delay and within the startup time frame.
