Adhesion
The adhesion of a coating on a substrate is crucial for the mechanical performance as well as for the corrosion protection.

Application
Constant and defined film thicknesses are the precondition for testing and analysis of coating materials and coatings.

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.

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.

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.

Film thickness
For cost and quality reasons the determination of both, the wet and dry thickness has become more important during the last years.

Fineness
The fineness of grind is particularly important during the manufacture of pigmented products.

Flexibility
Flexibility / elongation is the pliability or rigidity of a material. It expresses the extent to which it resists bending.

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.

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.

Skid resistance
This test is valid for flat road markings and road markings with low degree of texture.
