Cross hatch cutter is designed and manufactured in accordance with ISO 2409-1974.It is also complies with GB/T9286-98 standard.
The instrument is mainly used for the measurement of the grid scratching adhesion of the organic paints. It is not only applicable to the laboratories, but also good to the construction sites under various conditions.
There are three specifications of multi-blade cutters(1mm,2mm,and 3mm),which can be closed for different test conditions.
The multi-blade cutter with 1mm distance is suitable to the test pieces with the paint film less than 60um.
The multi-blade cutter with 2mm distance is suitable to the test pieces with the paint film of 60-100um
There are three varieties of this product:
1. The two knives for general use(1mm and 2mm)
2. The rotary three knives(1mm,2mm,and 3mm)
3. The cylindrical four sides(1mm,2mm)

| The edges of the cuts are completely smooth; none of the squares of the lattice is detached |
5B |
0 |
|
| Detachment of small flakes of the coating at the intersections of cuts. A cross-cut area not significantly greater than 5% is affected |
4B |
