Wet Film Thickness Gauge 234 R/II ERICHSEN Vietnam

 

 

Film thickness measurement plays an essential part in the use and testing of paints and coating materials. The film thickness is a decisive factor in determining appearance, protective qualities and durability.

A film which is too thin will afford inadequate protection and reduced hiding power. For this reason, technical specifications stipulate minimum film thicknesses and regular controls must be carried out to ensure that these values are consistent.

On the other hand, an excessively thick film is the result of using too much coating material, causing costs to increase accordingly. Furthermore, thicker coatings do not always mean an improvement in properties: for example, they have an adverse affect on drying time.

The physical and mechanical properties of a coating are directly dependent on the film thickness. If meaningful testing is to be conducted, the film thickness must therefore be uniform.

Wet film thickness gauges are used to check freshly applied coatings and can also be used to calculate the resulting dry film thickness. If deviations from the specified value are detected, corrective measures can be taken immediately.
