This stainless steel Coating Thickness Gauge is wire eroded to provide an accuracy of ±2.5µm (0.01mil) and are supplied with either Metric or Imperial measurements.
Each comb has 24 measurement stages (teeth) providing a more accurate wet film thickness value.
Whether you are applying a liquid or powder coating, by measuring the uncured film thickness, it is possible to determine the eventual dry film thickness. Applying too much coating not only wastes time and materials, it can also affect the performance and finish of the product. Too much wet film can cause the coating to crack as it cures; too little coating increases the risk that the substrate will not be sufficiently protected, leading to rust spots. In the powder coating industry, ensuring the end product has the correct levels of adhesion and appearance is dependent on the thickness of the powder prior to the curing process. Too much powder can lead to poor adhesion, too little can lead to a discolouration and loss in gloss of the coating The three methods for measuring wet film thickness are: – Wet Film Combs – Pfund Thickness Gauges – Wet Film Wheels. In each case, the thickness of the coating is measured and the dry film thickness can be estimated using the coating’s solid : wet ratio.
Using a wet coating thickness gauge (wet film comb):
Place a comb perpendicular to and touching the substrate. Hold the comb in position and wait a few seconds until the teeth are wet. Remove the comb from the film. The wet film thickness lies between the biggest value ‘coated’ or ‘wet’ tooth and the smallest value ‘uncoated’ or ‘dry’ tooth.
