Cross hatch adhesion testers

Description

Cross hatch adhesion testers – tools employed to perform adhesion related evaluations on single or multi-layer coatings. The instrument is composed by a handle and a metallic head. On the latter there are 6 or 11 blades laid out with a spacing of 1, 2 or 3mm. According to the spacing the head will be recommended to measure coatings respectively between 0 and 60µm, 60 and 120µm, or 120 and 250µm. The measuring procedure consists in sliding the selected head orthogonally on the sample, in order to track a grid on the coating. Comparing the status of the coating after the test with an internationally acknowledged table it’s possible to determine the adhesion grade. A magnifying lens and a transparent adhesive tape are used respectively to facilitate the operator and to keep record of the tests.

Employed in every industrial process concerning paintings and coatings.

Complying with standards: BS 3900 E6 - BS/EN ISO 2409 - ASTM D 3359 - GB/T 9286.
