Black Plastic-Vinyl Chloride/Acetate Copolymer
Smooth Matte Surface – Plasticizer Free
Used in ASTM D 2486, ASTM D 4213, ISO 11998 and Other Scrub Test Methods
In a typical scrub test, the coating is applied to the Leneta Scrub Test Panel at a specified film thickness, allowed to dry, then subjected to scrubbing with a straight-line scrub tester. In ASTM D 2486, a 10 mil shim is inserted under the panel to accelerate failure and thereby reduce testing time. The scrub resistance is the number of scrub cycles required to remove the coating to a specified end point. Alternatively, the loss in weight is determined after a specified number of scrub cycles as a measure of scrub resistance, with calculation of equivalent loss in film thickness.
Leneta Scrub Test Panels have a special, finely textured surface for enhanced adhesion. As paints are gradually worn down during the scrubbing process, a feathered edge” is produced which allows for a more precise determination of the end point
