Thin dry film can not provide enough protection but reduce the covering properties. So it must assure the consistency of these values by executing with the minimum thickness according to Technical Specification.

 

On the other hand, over painting will lead to a thick coating and in consequence the cost increases. Moreover, a thick coating doesn’t always mean a good performance. It might be a negative effect at drying time.

 

Physical and mechanical performance of the coating is determined by thickness of dry film. Executing a meaningful test needs a well-proportioned dry film. Wet film thickness gauge is available to test paint which just brushed and calculate the thickness value of dry film. If there is different between measurement and indicated value, it needs to be corrected immediately. Dry film thickness gauge is used for measuring thickness of final coating.

A series advantages of mechanical thickness gauge:

1. Portable and easy operation is convenient for nontechnical people. Rugged structure, direct reading.

2. Test runs at any surface. The whole mechanical design is applicable to glass, wood, metal and plastic material.

3. Compare to other thickness gauge, mechanical one offers a more competitive price.

234 Wet Film Thickness Gauge, matches ISO 2808, ASTM D 1212, BS 3900:C5 Standard

Having same length, the 1^st tooth and the 12^th tooth comb shaped gauge go through the wet film to the material. Between the 2^nd tooth to tooth 11, the distant to material increases gradually. The 6^th tooth and the 11^th tooth are put into the coating but the 2^nd tooth and the 5^th tooth will not touch the paint. In consequence the measurement is an average value of the 5^th tooth and the 6^th tooth. 

Design and Function:

The rectangle gauge is made from stainless steel. The teeth on two sides are well cut for having descending distant to material and showed on the indicator.(Unit: μm)

Measure Process

Measure teeth have a default thickness range for wet film. Put it straight on the measuring surface, push it with a short combing movement and lift it upright. The thickness value of wet film can be read on the tooth with few coating.
