Coating Does the Job of Rubber, Tile

Wednesday, April 22, 2015

GROVELAND, MA—A new trowel-applied coating can replace conventional rubber linings and ceramic tile commonly used in aggressive chemical slurry applications at elevated temperatures, its manufacturer says.

T7 AR is a high-performance, abrasion-resistant novolac vinyl ester-based resin coating for metallic surfaces from A.W. Chesterton Company's ARC Efficiency & Protective Coatings.


The trowel-applied coating is specially treated with a graded blend of high-purity alumina ceramic beads, flakes and powders, according to the company.

The company says the coating resists:

  • Wet and dry thermal cycling from 275 degrees F (135 degrees C) to 35 degrees F (2 degrees C);
  • pH ranges from .1 to 12.5; and
  • Sliding abrasion wear associated with ore refining and processing.

The trowel-applied coating is treated with a graded blend of high-purity alumina ceramic beads, flakes and powders.

The product has withstood testing with a wide range of chemicals, including phosphoric acid, sodium hydroxide, glacial acetic acid and nitric acid at temperatures up to 185 degrees F (85 degrees C).
