Film thickness

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

Wet film thickness

For several reasons it is important to determine the thickness of freshly applied liquid (”wet”) coatings: The applied film thickness is often decisive for the quality of the coated product. On the other hand, the quantity of applied material should not be too high, both for technical and economical reasons.

Dry film thickness

For several reasons it is important to determine the dry thickness of coatings: Many coating properties such as adhesion and hardness depend on the dry film thickness. The measurement methods for measurements of dry film thickness can be classified as destructive and non destructive.

Destructive dry film thickness determination

The destructive wedge cut method is particularly important for determining the dry film thickness on substrates such as wood, concrete, plastic and other non magnetic substrates. On these substrates most of the conventional non destructive electro-magnetic methods cannot be used.

Non-destructive dry film thickness determination

Zehntner offers two dry film thickness gauges for checking or measuring the dry film thickness of road markings.
