Features

Coated and uncoated surfaces need to be tested for resistance to abrasion caused by a brush, sponge, scouring pad, sand paper, and other means. Abrasion resistance can be tested by wet abrasion methods using scrub media or cleaning solutions. The most common applications are testing the scrub resistance of interior wall paints, floor tiles, shower stalls, and furniture surfaces. The abrasion tester can examine the washability of a coated surface for the removal of stains. Detergents and cleaning solutions can be tested and evaluated in a reproducible manner.

Procedure

Attach the samples in the acrylic sample boxes
Fill in a freshly prepared aqueous suspension
The stroke length of the instrument is 130 mm ± 2 mm in two parralel boxes
Attach a wiper blade (e.g. CR Bosch Profile 32) with a load of 15 g/cm (80 mm blade 120 g)
Test two samples on a double stroke instrument parralell or in row
Setup instrument to 10.000 cycles
Samples need to be turned after 10.000 cycles
Run test for another 10.000 cycles
Measure transmission haze of cleaned and dried surface
