How do you accurately measure the adhesion of inorganic zinc?

From Tolga DIRAZ of CARBOLINE Turkey - Bursa Plant on July 10, 2013:
I agree with Atanas and would not recommend a cross-cut adhesion test. I believe electronic P\pull-off adhesion testers like DEFELSKO POSITEST Pull-off adhesion tester might give more precise results.

From Atanas Cholakov of ACT on July 3, 2013:
This kind of coating develops a rock hard surface, but it is brittle once fully cured. Further, these coatings are prone to poor internal cohesion due to the high load of zinc (the necessary conductivity for galvanic protection). Their maximum thickness goes to 4-5mils on static equipment and often 3-4mils if the piece has to travel. I personally wouldn’t resort to the D 3359 or D 6677 suggested test methods by the ASTM in this scenario. Tensile strength pull-off test as suggested by Jordon might be the better option to gauge adhesion. However, prior to attempting the test, you've got to make sure that the coating is fully cured. MEK  or pencil hardness tests are recommended or get your coating supplier's opinion.

From Jordon Maceachern of powerwash restoration inc on June 20, 2013:
Measure the pull-off strength using a pull tester and dolly properly glued to the surface (such as an eclo 106 adhesion tester). Follow method described in ASTM D4541

From mohamed okaz of international maritime group on June 19, 2013:
Measure adhesion of inorganic zinc by using x-cut method.

From Dnyaneshwar Narode of TATA AUTOCOMP STSTEM LTD on June 14, 2013:
Use An Elecometer Adhesion Tester
