Belzona 1111 (Super-Metal)

Belzona 1121 (XL Super-Metal)

Application Situation
Mining: Corrosion repairs needed to 8 x Nickel Storage Silos.
Application Method
The application was carried out by Cold Bonding 200mm x 1m rolled plates with Belzona in accordance with the Method Statement for Cold Plate Bonding. After abrasive blasting, all corrosion holes were first repaired by filling with Belzona 1111. Belzona 1111 was then applied to the plates which were bonded into place. Belzona 1121 was used when temperatures rose above 35 C to allow more working time.
Belzona Facts
Belzona Cold Plate Bonding system was chosen because it was safer and more cost effective than welding alternatives. The cold application saved the internal coating and the need to empty each silo. This saved time and avoided any down time which would have cost thousands of dollars. Additionally, the Belzona solution is as strong as welding and eliminates the void where corrosion can continue.
