Adhesion Test

The "Cross Hatch" test has been used widely in various forms in order to assess the adhesion of paint coatings. Its technical merit has been recognized by International Standards authorities as a method of test for this property of attached coatings, which also depends on other factors e.g. flexibility of coating, the presence of interference layers between coating and substrate etc. The test method specifies suitable cutting tools with either single or multiple cutting edges. It has advantages over the single cutting blade for both safety and simplicity in use.
