Cross Cut Paint Adhesion Test

3 2 test method b a lattice pattern with either six or.

Cross cut paint adhesion test. Cross cut testing and x cut testing 3. Cross cut testing for paint adhesion on small parts may prove difficult. Method a x cut tape test and method b cross cut tape test. 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.

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. Two series of parallel cuts cross angled to each other to obtain a pattern of 25 or 100 similar squares. Before painting apply a consolidating fixative primer to the grid and once dried repeat the test to evaluate adhesion. There are several different tests to measure the resistance of paints and coatings from substrates.

Using the appropriate method. Iso 2409 paint and varnishes cross cut test4 3. 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. The paint has flaked partially or completely along the edges and or some squares have partially or completely detached.

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. Paint adhesion test kit. Cross cut test scrape adhesion pull off test and others. This method is utilized in evaluating the adhesion of either one or multiple coats.

This video demonstrates techniques for handling small or unusual parts for crosshatc. Iso 4624 paints and varnishes pull off test for adhesion 2 iso 16276 2 corrosion protection of steel structures by protective paint systems assessment of and acceptance criteria for the adhesion cohesion fracture strength of a coating part 2. The x cut tape test and the cross hatch tape test. There are two variants of this test.

Astm d3359 describes two test methods for evaluating tape adhesion of a coating system. A cross cut area of between 15 to 35 is affected. The x cut tape test is primarily intended for use at job sites.
