Abrasion resistance

is the resistance to abrasive stress and its effect on paints, e.g. by walking on floors or by brushing. This stress is created in the laboratory by abrasion testing devices. The main way to do this is to go over the test surface with an abrasive-covered surface or an electric friction wheel. In the main, the Taber Abraser test is used in accordance with DIN 53 754. Sanding the paint is another basic principle: Standardised sand falls from a small pipe onto the tilted paint surface. The amount of sand required to wear through the paint is taken as the benchmark for the abrasion resistance. The sanding can be intensified by means of a compressed air feed.
