TQC Comprehensive Abrasion Test

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

The TQC 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 TQC Comprehensive Abrasion Test is used in coating test laboratories for quality control work.

WHY THIS ABRASION TEST?

Beverage cans often suffer from severe scuff and friction during transport. Typically foodstuff in damaged packaging is hard- if not impossible to sell to the consumer. A small scratch is enough to make the merchandise worthless. And it can be worse…

If the paint (or ink) does not survive the scuffing movements during transport and bare aluminium starts to scuff against bare aluminium a can may start to leak within minutes. Especially carbonated drinks will spray and spill over the entire consignment thus destroying more or less the a complete pallet.

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.

Since the failure of the coating can have two causes testing has to be done at both paint makers end and at the side of the can maker / paint applicator.
