Adhesion testers / cross cutters
This sub-category groups together our coating adhesion testing solutions.
- Tear adhesion testers: Tensile tests on pads previously glued to the coating in order to determine the force required for their tearing (recommended for thick coatings)
- Grid combs: The test consists of making a grid of the coating and evaluating the number of squares thus formed that will be detached.
As a reminder, standard ISO 2409: 2013 Paints and varnishes - Cross-cut test recommends:
Coatings less than 60 microns: 1 mm 6 teeth
Coatings between 60 and 120 microns: 2 mm 6 teeth
Coatings greater than 120 microns: 3 mm 6 teeth
