Belzona® Avoids Costly Downtime By Patching Fuel Bladders

 
 

Industry:

General Industry (GIND)

 
 

Application:

Solids Handling Machinery (SHM)

 
 

Customer Location:

Alaska, USA

 
 

Application Date:

1983

 
 

Application Situation:

Damaged fuel bladders.

 
 

Problem:

Scrapes on the outer rubber layer of the large towable fuel bladders would allow water to wick into the fabric, weakening the fuel bladder.

 
 

Products:

Belzona 2221 (MP Fluid Elastomer)

Belzona 2911 (Elastomer QD Conditioner)

Belzona 9341 (Reinforcing Sheet)

 

Substrate:

Fabric Reinforced Rubber

 
 

Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflet SHM-9. The surface was roughened and Belzona 2911 was applied and allowed to cure. Belzona 2221 was brushed on and Belzona 9341 was stippled in. Two hours later a final coat was brushed over the surface.

 
 

Belzona Facts:

Patching the bladders was done by using a hot vulcanizer allowing them to do one path at a time. Bladders with multiple scrapes could take a week or more to repair. With Belzona 2221 several bladders could be repaired every day, putting them back in service faster and saving thousands in labor.
