Contact SupplierScratch hardness tester is a tool to check the resistance of the coating against the scratching due to external physical strain. In this test, a metal piece is coated with the sample of paint or varnish or lacquer that is to be tested. A needle is used to scratch the sample. A specified load is applied on the sample via needle as per the industrial requirements. The needle makes repeated attempt to scratch the sample. The sample is put to test by setting the number of movements of the needle. The test can be done on all type of coatings and other bulky materials like plastics, elastomers and rubbers.
Presto offers motorised model of scratch resistance tester to minimise the human interference. In this machine, there is a motorised assembly to move the needle to and fro, a specified weight is applied on the needle as per the industrial standards. This test determines the scratch resistance and wear and tear of the sample. This machine is widely used in laboratories, quality management departments of the manufacturing units.
