Powder Coating Thickness Gauge - Uncured

Powder Coating Thickness Gauge - Uncured is a gauge that can measure the thickness of uncured powder non destructively and with no contact. It is important that a coating is applied to the correct thickness. Applying too much wet coating will not only waste time and money, but there is also a possibility of the coating cracking during the curing process. Too little coating and there is a chance that the substrate will not be sufficiently covered. To control process variables, it is often desirable to measure whilst the film is still wet. Wet film measurements are also useful for systems where the dry film thickness can only be measured destructively. The cured dry film thickness is determined by the level of shrinkage, which in turn is influenced by factors such as particle size and density of the uncured powder. As all manufacturers' coatings are different, it is not generally possible to predict the dry film thickness post cure unless the level of shrinkage is known or the pre cure powder density is measured. Measuring the thickness of the uncured powder is difficult. Whereas wet film measurement is non-destructive, the measurement of powder thickness using any form of contact with the uncured coating disturbs the powder - altering its thickness.
