The Comprehensive Abrasion Test is a universal test machine to test the coating abrasion resistance on beverage cans or flat materials. The reciprocating motion mimics in-the-field transportation abrasion damage of coatings equivalent to the Gavarti Associates “GV-CAT” system. The Comprehensive Abrasion Test is used in coating test laboratories for quality control work.
History Comprehensive Abrasion Test
Decades ago a small company out of the USA produced a machine to test the abrasion resistance of inks and coatings on aluminium beverage cans. The device simulates the motion of a truck or train during shipping and is used for assessing the transit scuff resistance of printed cartons and book covers as well as cans.
The printed sheet is sandwiched between oblong blocks of polyurethane rubber. A plain or printed sheet of the same stock is placed in with it and then hydraulic rams push the blocks from the side in a wave motion to simulate transit vibration. At the end of the test, the print-to-print or the print-to-plain-paper can be examined for scuffing.
