Product Details
In a typical scrubbing process, the coating is applied to the Leneta scrubbing test panel at a specific thickness, and after drying, it is scrubbed using a linear scrubbing tester.
In method A of ASTM D2486, insert a 10 mil thick thin gasket underneath the test plate to accelerate failure and shorten testing time. Scrubbing resistance refers to the number of scrubbing cycles required to remove a coating to a specified endpoint.
Alternatively, after a certain scrubbing cycle, the weight of the coating loss can be determined, and the amount of film thickness loss can be calculated to measure the scrub resistance.
These scrubbing test panels are suitable for use withElcometer 1720Used in conjunction with a washable and scrub resistant tester.
