Cross Cut Paint Adhesion Test

Astm d3359 describes two test methods for evaluating tape adhesion of a coating system.

Cross cut paint adhesion test.

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. 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. Method a x cut tape test and method b cross cut tape test. This video demonstrates techniques for handling small or unusual parts for crosshatc.

3 2 test method b a lattice pattern with either six or. There are two variants of this test. Cross cut testing for paint adhesion on small parts may prove difficult. There are several different tests to measure the resistance of paints and coatings from substrates.

Cross cut testing and x cut testing 3. The x cut tape test is primarily intended for use at job sites. This method is utilized in evaluating the adhesion of either one or multiple coats. 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.

A cross cut area of between 15 to 35 is affected. Before painting apply a consolidating fixative primer to the grid and once dried repeat the test to evaluate adhesion. Using the appropriate method. Iso 2409 paint and varnishes cross cut test4 3.

Cross cut test scrape adhesion pull off test and others. 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. The paint has flaked partially or completely along the edges and or some squares have partially or completely detached. 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. The method selected is based on the total thickness of the coating system to be evaluated.
