Impact tester for paint. Impact test of paint coatings applied to metal base. ISO, DIN, ASTM. The Impact Tester is used for measuring the resistance of coatings to impact. Thanks to it you can simulate the production of cracks and peeling, resistance to shocks, the flexibility, adherence and elongation of coatings.In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test, and others. [1]

The “peel test” is a typical industry standard procedure that offers the opportunity to see under real conditions that the tape has been applied correctly. According to the manufacturer, the adhesion should be cohesive (see photo 1) and should adhere to both the substrate and the pipe itself.Testing Conditions:Paint testing is carried out both on liquid paints and on cured coatings. Depending on the application, these are subjected to varying loads – under laboratory conditions or in outdoor weathering. For this purpose, the researchers use standardized test procedures, but also develop customized test and testing methods if required.
