Gloss is the optical property of a surface to reflect light into the specular direction, an important appearance factor. The visual impression of gloss is dependent on the individual perception, therefore the gloss values are determined using glossmeters. Zehntner is the leading manufacturer of top class glossmeters.

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 testThe 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 testMandrel 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.

Adhesion
The adhesion of a coating on a substrate is crucial for the mechanical performance as well as for the corrosion protection.
Click here to see our products for adhesion.
Application
Constant and defined film thicknesses are the precondition for testing and analysis of coating materials and coatings.
Click here to see our products for application.
Chalking
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.
Click here to see our products for chalking.
Corrosion
Many standards describe corrosion tests where a coating has to be prepared with scratch marks that penetrate it completely down to the metal substrate.

Cross-cut
The cross-cut test is a very rapid and simple method for the assessment of single and multi-coat systems.

Day visibility
Measures the luminance coefficient under diffuse illumination (day visibility) of road markings.

Density
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.
Click here to see our products for density.
Drying properties
Drying properties, shrinking, mud-crack, cracking and porosity are important characteristics which should be tested during the manufacture of coating materials and fillers.
Click here to see our products for drying properties.
Film thickness
For cost and quality reasons the determination of both, the wet and dry thickness has become more important during the last years.
Click here to see our products for film thickness.
Fineness
The fineness of grind is particularly important during the manufacture of pigmented products.
Click here to see our products for fineness.
Flexibility
Flexibility / elongation is the pliability or rigidity of a material. It expresses the extent to which it resists bending.
Click here to see our products for flexibility.
Gloss
Gloss is an optical property of a surface, characterized by its ability to reflect light.

Hardness
Hardness testing is an easy and fast method to determine the force needed to scratch a surface.

Night visibility RL
The nicht visibility measures the coefficient of retroreflected luminance (night visibility) of road markings.
Click here to see our products for night visibility RL.
Retroreflection
The visibility is an important factor for many road signs, road markings, traffic signs, road studs as well as high-visibility material such as warning clothes and Heavy good vehicles (HGV's) contour safety marking.

Road marking
The visibility of road markings is a crucial factor in ensuring traffic safety. Hence it is inevitable that road markings are checked, maintained and if necessary replaced on a regular basis.

Roughness
The roughness of a surface can be defined by it's macro texture.
Click here to see our products for roughness.
Skid resistance
This test is valid for flat road markings and road markings with low degree of texture.

Gloss
Gloss is an optical property of a surface, characterized by its ability to reflect light. If a light beam strikes a surface - e.g. a lacquer - with a certain angle of incidence (ε), most of it will penetrate the layer of paint, the rest will be reflected.
