Abrasion resistance is the ability to withstand the frictional forces attempting to remove the surface material.

Applicator for preparing uniform films of coating materials, adhesives and similar products on flat and flexible substrates with an automatic film applicator or for manual application.

Applicator for preparing uniform films of coating materials, adhesives and similar products on flat and flexible substrates with an automatic film applicator or for manual application.

The adhesion of a coating on a substrate is crucial for the mechanical performance as well as for the corrosion protection. In practice, there are several test procedures for determining the adhesion such as cross-cut test, mandrel test and impact test.

Cross-cut test

The cross-cut test is a very rapid and simple method for the assessment of single and multi-coat systems. Here, cuts in a 30° angle (method A) or right-angle (method B) are executed so that you receive a lattice pattern or an X-shape. These test methods can be used as quick pass/fail tests. When applied to a multi-coat system, assessment of the adhesion of individual layers of the coating among each other may be carried out.

Bend test

Mandrel testers are common test apparatuses used for the determination of the elongation/and adhesion of coatings at bending stress. At a bend test a test panel is bend over a certain radius.

Conical mandrel testers bend the test panels over a conus so that a large variety of bending radii is tested at the same time.

The cylindrical mandrel test can be carried out as a quick pass/fail test with a single mandrel of specified diameter or as repeated procedure with decreasing mandrel diameters for determining the diameter of the first mandrel causing failure.

Impact test

Impact tests are a test method for evaluating the resistance of a dry film of paint, varnish or related product to cracking or peeling from a substrate when it is subjected to a deformation caused by a falling weight dropped under standard conditions.

Constant and defined film thicknesses is a precondition for testing and analysis of coating materials and coatings. Many properties of these materials depend on the film thickness.

It is important to know that for physical reasons the maximum achievable wet film thickness is not equal to the gap height. The following guidelines apply:

Gap heightWet film thickness
15 - 100 µm (0.59 - 3.94 mil) about 50 %
above 100 - 300 µm (3.94 - 11.81 mil) about 60 %
above 300 - 500 µm (11.81 - 19.69 mil) about 80 %
above 500 µm (19.69 mil) up to 90 %


For the choice of the correct gap height please also consider that the dry film thickness obtained can be less than the wet film thickness depending on the weight percent of solids.

There are wedge-shaped and uniform applications. For wedge-shaped applications, we offer the ZUA 2000 and ZUA 2002 Universal Applicator. There is a wide choice of uniform applicators from wire-bar, profiled, semi-circular, 4-sided up to universal applicators.

The degree of chalking, a measure for the amount of particles exposed by chalking, is determined by the reduction in the intensity of light passing through the adhesive tape after having applied to the coating.

Chalking is the appearance of a loosely adherent fine powder on the surface of a paint coating arising from the degradation of one or more of its constituents (EN DIN ISO 4628).

The chalking tester which measures the chalking resulting from natural or artificial weathering of coatings is based on the analytical principle of nephelometry and the adhesive tape method according to Helmen.

The following devices are in accordance with the general basic principles of a CIE standard:

The following devices are in accordance with the general basic principles of CIE 54.2:

The term colour fastness refers to two resistance criteria of a colour of a test sample. The first criterion is the resistance of a material to change in any of its colour characteristics. The second criterion is the resistance of its colourant(s) to adjacent materials as a result of exposure of the material to any environment that might be encountered during the use of the material.


The first resistance criterion is checked by the “rubbing fastness” test. The term “rubbing fastness” is the term for the hue change of the test sample through rubbing. This test is evaluated visually with a comparative scale. Most common is the use of a “gray scale for staining”.


“Crocking” and “smudging” are both equivalent terms for the transfer of colorant(s) from the test surface to another surface or to an adjacent area by rubbing. Therefore, if the second resistance criteria is checked, you test the crock resistance (equally called smudge resistance).

Many standards describe corrosion tests where a coating has to be prepared with scratch marks that penetrate it completely down to the metal substrate. Possible instruments are scratching tools according to Sikkens or Clemen and Cross-cut testers.

 

The cross-cut test is a very rapid and simple method for the assessment of single and multi-coat systems. Here, cuts in a 30° angle (method A) or right-angle (method B) are executed so that you receive a lattice pattern or an X-shape. These test methods can be used as quick pass/fail tests. When applied to a multi-coat system, assessment of the adhesion of individual layers of the coating among each other may be carried out.

Choice of the appropriate cross-cut method

  • Methode A (X-cut) for tests in accordance with ASTM D 3359 with thickness > 125 µm (4.92 mil)
  • Methode B (lattice pattern) for tests in accordance with ISO 2409 with thickness 0 - 250 µm (0 - 2.36 mil) and ASTM D 3359 with thickness <125 µm (4.92 mil)


Choice of the appropriate spacing of cuts (method B) in accordance with ISO 2409:

Film thicknessSubstrateSpacing of cuts
0 to 60 µm (0 to 2.36 mil) hard 1 mm (0.04“)
0 to 60 µm (0 to 2.36 mil) soft 2 mm (0.08“)
over 60 to 120 µm hard or soft 2 mm (0.08“)
over 60 to 250 µm (2.36 to 4.72 mil) hard or soft 3 mm (0.12“)


Choice of the appropriate spacing of cuts (method B) in accordance with ASTM D 3359:

Film thicknessSpacing of cuts

The day visibility is a method to assess road markings. It measures the luminance coefficient under diffuse illumination (day visibility) of road markings. The observation angle of 2,29° corresponds to the viewing distance of a vehicle driver of 30 m under normal conditions. The illumination must be diffused light.

Day visibility Qd

 

The density is an essential quality characteristic, for example it allows recognising errors regarding the composition and gives indications of the purity of a product.

The test principle is based on the weighing of a given volume of the liquid under test, as it is defined by the pycnometer. From the difference of the masses of the filled and the empty pycnometer as well as the known filling volume the density is calculated. The density p in g/ml at the test temperature t can be calculated using the following equation:

    p = (m2 - m1) / Vt

p = density in g/ml of the sample at the test temperature t
m1 = mass in g of empty pycnometer
m2 = mass in g of probe filled pycnometer at the test temperature t
Vt = volume of the pycnometer in ml at the test temperature t

The result is not corrected for air buoyancy because the uncorrected value is required by most filling-machine control procedures and the correction (0.0012 g/ml) is negligible in relation to the precision of the method.
