Paint film cross-cut tester/cross-cut adhesion tester manufacturer

The tester is a general purpose tool for performing many different scratch and nick tests on painted and plastic surfaces.

Product Introduction

Simple Introduction
Paint cross-cut tester is a general purpose instrument used to perform many different scratch and nick tests on painted and plastic surfaces. For test pieces of different thicknesses, a single or multi-column scriber can be used for parallel marking and cross marking (turn the sample 90°).

Application range
Paint film cross-cut tester is a kind of scratch-resistant and anti-universal instrument for nick test. For test pieces of different thicknesses, a single or multi-column scriber can be used for parallel marking and cross marking (turn the sample 90°).
Especially for alluser standards perform the adhesion test according to the cross-cut method, and perform the anti-scratch test according to GME 60 280. A wide range of test parameters and a wide selection of test tools make these tests easy to perform.

Features:
Used to evenly draw a grid of a certain size and assess the integrity of the coating film in the grid. adhesion of the coating film to the substrate, expressed in \'grade\'. It is mainly used for determining shading adhesion of organic coatings, not only for laboratories, but also for construction sites under various conditions. The instrument is especially suitable for determining the shaded adhesion of organic coatings. It is not only suitable for laboratories, but also can be used on construction sites under various conditions.

Operation and use
1. Place the test piece on a flat plate of sufficient hardness.
2. Hold the handle of the scratcher and make the cutting bladewith several blades perpendicular to the plane of the test piece.
3. Cut with even pressure, constant and non-vibrating technique and cutting speed of 20-50mm/S.
4. Rotate the specimen 90 degrees and repeat the above operation on the incision made to form a grid pattern.
5. Use a soft brush to brush the diagonal lines on both sides of the grid pattern and gently brush the sample 5 times backwards and 5 times forwards.
6. The test must be completed on at least three different positions of the test piece. If the test results of the three positions are different, the test should be repeated at more than three positions and all results recorded at the same time.
7. If you need to replace the multi-blade cutting blade, you can use a screwdriver to unscrew the two screws on the blade, replace it with the blade you use, stick the blade edge on the side von the handle and tighten the screws.

Precautions
1. All cuts must penetrate the coating, but not too deep into the substrate.
2. If the coating is too thick and hard to penetrate the substrate, the test is invalid, but it should be stated in the test report.
3. Test tape Stick the tape to the entire net, then tear it off at the smallest angle. The result can be obtained according to the ratio of the glued area to the surface of the paint film.
4. The test should be performed at a temperature of 23±2°C and a relative humidity of 50±5%.
