Cross cut paint adhesion test.

3 2 test method b a lattice pattern with either six or. The x cut tape test is primarily intended for use at job sites. Using the appropriate method. Cross cut testing for paint adhesion on small parts may prove difficult.

Summary of test methods 3 1 test method a an x cut is made through the film to the substrate pressure sensitive tape is applied over the cut and then removed and adhesion is assessed qualitatively on the 0 to 5 scale. The method selected is based on the total thickness of the coating system to be evaluated. A cross cut area of between 15 to 35 is affected. Method a x cut tape test and method b cross cut tape test.

Two series of parallel cuts cross angled to each other to obtain a pattern of 25 or 100 similar squares. The paint has flaked partially or completely along the edges and or some squares have partially or completely detached. There are several different tests to measure the resistance of paints and coatings from substrates. Using a sharp razor blade scalpel knife or other cutting device two cuts are made into the coating with a 30 45 degree angle between legs and down to the substrate which intersects to form an x.

Paint adhesion test kit. The x cut tape test and the cross hatch tape test. The tqc cross cut adhesion test basic cutter is used to test the adhesion of dry coats of paint on their substrate by means of a series of cuts through the coating. There are two variants of this test.

Iso 2409 paint and varnishes cross cut test4 3. This method is utilized in evaluating the adhesion of either one or multiple coats. Astm d3359 describes two test methods for evaluating tape adhesion of a coating system. Before painting apply a consolidating fixative primer to the grid and once dried repeat the test to evaluate adhesion.

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. Cross cut testing and x cut testing 3. Cross cut test scrape adhesion pull off test and others.
