Astm Paint Adhesion Scratch Test

This paint adhesion cross cut tester offers a high quality and precision engineered round shaped blade holder presenting selectable blades with 6 or 11 teeth and a.

Astm paint adhesion scratch test.

Normally after 30 days a second test should be performed. This procedure can also be administered on site and provides quantitative results in. A total of 11 parallel cuts are made with a sharp instrument 1mm apart in both a vertical and horizontal direction forming a grid. Pressure sensitive tape is applied and removed over cuts made in the coating.

Functional behaviour of a coating is critical to its adhesion to the substrate. One inch wide pressure sensitive. Qualtech products industry cross cut adhesion tester cross hatch cutter is a professional instrument engineered to conveniently evaluate the adhesion performance of coatings applied onto specimen. On metal substrates a more formal version of the knife test is the tape test.

However reliable and reproducible test results require careful control of the test system configuration and testing parameters detailed analysis of the coating damage features and appropriate characterization of the properties and morphology of the coating and the substrate of the test specimens. 5 2 the quantitative coating adhesion scratch test is a simple practical and rapid test. 1 1 this test method covers the determination of the adhesion of organic coatings such as paint varnish and lacquer when applied to smooth flat planar panel surfaces. A standard method for the application and performance of this test is available in astm d6677.

The x cut tape test and the cross hatch tape test. Other related test methods. There are two variants of this test. Through the patterns and methods of astm d3359 17 s procedures adhesion can be much more easily and reliably measured.

June 5 2012 4 scratch tests 1. For additional test methods related to astm d3359 we invite you to read more about our coating testing services. Scratch test is one of widely used fast and effective methods to obtain the critical loads that are related to adhesion properties of coating. As coatings continue to cure the adhesive properties will change.
