| Problem: |
| |
 The company was having problems with its cake slurry tank. The original manufacturer had coated the tank with a coal tar substance to protect the carbon steel. Due to the high degree of acidic concentrate contained in these tanks, the interior bottom had corroded significantly, leaving absolutely no remnants of the original coal tar coating. |
| Solution: |
| |
 Because of the corrosive nature of the materials contained in the company’s cake slurries, a thin coating was not the optimal choice for this application. Rhino Linings was chosen because of its protective capabilities in highly corrosive environments. Rhino Linings’ Hi-Chem™ formulation was sprayed at a thickness of ½” on the bottom of the tank and ¼” on the sidewalls of the tank. |
| Results: |
| |
One year after application, the company did an inspection of their cake slurry tank. There had been absolutely no wear on the Rhino Linings. The company was so pleased by the results that they decided to apply Rhino Linings’ Hi-Chem as an impermeable barrier for their concrete holding tanks.
