Wet-film
In order to better control the change process of surface construction film, engineers usually perform coating thickness measurement in the wet-film state of Coating. Wet-film measurement equipment depends on the shape of the measurement surface area and the measurement range of the system. In addition, when dry-film thickness can only be measured when it is damaged, the effect of wet film thickness is particularly obvious.
Dry-Film
Accurate thickness measurement controls product mass and saves material consumption. Dry-Film measurement enables damage-free measurement and multi-level damage measurement.
The relationship between wet-film and Dry-Film
It is generally believed that the relationship between Dry-Film and wet-film for most Coatings is as follows:
Dry-Film = (wet-film X Coating solids%)/100
As we all know, misestimation of Coating thickness will lead to unnecessary waste of time, materials and money. Film is too thin, resulting in insufficient hiding power and protective performance, resulting in the need to re-paint and waste time. Conversely, when painting Dry-Film with too thick construction, this may cause defects such as checking, flaking, and excessive stoving drying time. Of course, the cost of painting also increases. This is the reason and effect of controlling coating thickness.
