Cold-applied repair
17 October 2016
Belzona was recently contacted by a UK-based company specialising in the restoration of dilapidated trains. Train refurbishment involves dismantling in order to conduct repair and maintenance, before repainting and returning to a like-new condition.

During the refurbishment process, the company identified a recurring corrosion problem with the diesel tanks; in some instances, this appeared as pitting or even holes. The current repair method comprised welding steel pates into place; however, this was causing further problems due to distortion from HAZ (heat-affected-zones).
The customer required a cold-applied solution to repair these defects, ensuring that further damage from hot work did not compromise and slow the repair process. Belzona 1121 (Super XL-Metal) was selected as an appropriate material to restore the diesel tanks to working condition. With application and curing at room temperature, Belzona 1121 offered a corrosion resistant solution which eliminated the threat of HAZ and allowed the repaired tanks to be rapidly refitted.
