Varnish Washability Tester

The varnish scrub resistance tester simulates daily scrubbing processes by using a motor to drive a brush in a reciprocating motion on the coating surface. During testing, the brush is dipped in detergent and scraped back and forth on the sample board, recording the number of scrubbing cycles when the coating begins to show damage. This instrument is used to evaluate the scrub resistance of coatings such as wall paints and wood finishes, providing a basis for product quality control.
Selection
When selecting, consider matching the brush material and stroke with testing standards, ensuring the motor maintains stable reciprocating frequency. The sample clamping device should accommodate substrates of varying thicknesses, and the counter must accurately record the number of cycles. Equipping an automatic liquid dispensing system helps maintain consistent scrubbing concentration, while the instrument structure should facilitate easy cleaning and maintenance.
