MODERNER QFH 1mm (10 grooves) paint film scratcher is designed and manufactured according to the ISO2409 standard. The paint film cross-cut device is mainly suitable for the determination of the cross-cut adhesion of organic coatings, not only for laboratories, but also for construction sites under various conditions.
The paint film cross-cutting device cuts and penetrates the coating according to the lattice pattern, and the completed cross-cut pattern is classified into six grades to evaluate the resistance of the coating to separation from the substrate.
QFH paint film scratcher has multi-blade cutting knives (1mm, 2mm, 3mm) with three specifications of spacing, which can be selected according to different test conditions. The multi-blade cutting knife with 1mm spacing is suitable for test pieces with coating film thickness <60μm, the cutting knife with 2mm spacing is suitable for test pieces with coating film thickness 60-100μm, and the cutting knife with 3mm spacing is suitable for coating film thickness 60-150μm test piece. The test piece should be made of glass, tinplate, aluminum, etc. as the substrate.
