Solvent Rub Resistance Tester is used to measure the solvent – resistant wiping property of coating.The wiping head with a certain speed and wiping pressure (the absorbent cotton wetted with useful solvent for contacting the bread) is used to reciprocate wipe on the surface of the sample. The wiping times can be directly read by the counter. According to the wiping times needed for the coating to be damaged, the solvent resistant wiping performance of the coating can be evaluated.This product conforms to standards :GB/T 23989, ASTM D5402.
