Cross Cut Paint Adhesion Test

The x cut tape test is primarily intended for use at job sites.

Cross cut paint adhesion test. The procedure consists of cutting a pattern of perpendicular lines through the adhesive all the way to the substrate then spreading pressure sensitive tape over the cuts and rapidly pulling it off. This video demonstrates techniques for handling small or unusual parts for crosshatc. Before painting apply a consolidating fixative primer to the grid and once dried repeat the test to evaluate adhesion. Cross cut test scrape adhesion pull off test and others.

Two series of parallel cuts cross angled to each other to obtain a pattern of 25 or 100 similar squares. Iso 2409 paint and varnishes cross cut test4 3. The method selected is based on the total thickness of the coating system to be evaluated. The paint has flaked partially or completely along the edges and or some squares have partially or completely detached.

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 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 several different tests to measure the resistance of paints and coatings from substrates. Astm d3359 describes two test methods for evaluating tape adhesion of a coating system.

Cross cut testing for paint adhesion on small parts may prove difficult. 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. 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.

The paint adhesion test kit also known as cross cut kit by precision gage tool company provides everything you need to perform adhesion and flexibility tests to meet the standards of the astm test method d 3359 each kit includes a blade a blade holder handle a hex wrench for changing blades an extra clamp screw a small flaking and cleaning brush a lighted. There are two variants of this test. 3 2 test method b a lattice pattern with either six or. Cross cut testing and x cut testing 3.
