Elcometer 155 Uncured Powder Film Comb
 


Available in four scale ranges, the Elcometer 155 is designed to measure uncured powder coating film thickness. This enables the application system to be set up and fine tuned prior to the curing process. In turn, this will reduce the amount of scrap and over-spray. Simply place the comb into the powder and draw the comb towards you. The measurement points (or teeth) are pointed and allow the powder to flow around them. The thickness of the powder lies between the biggest value where a drag mark is visible and the smallest value where a drag mark has not been produced. Note: The thickness of a coating prior to cure is not necessarily the value after curing. The powder comb is only suitable as a guide only

Powder Thickness Measurement – uncured
A powder coating has many advantages over a wet coating system, including:
• Little or no waste– excess powder or oversprayed powder can be recycled and reused
• No solvents – new, tighter environmental controls of VOC emissions and legislation increases the need to use less or no solvents.

Making sure that the end product has the correct levels of adhesion and appearance - in particular gloss and colouris dependent upon the thickness of the powder prior to the curing process, and the temperature profile of the oven.

Measuring the thickness of powder however, is difficult as touching it changes the powder thickness compressing it under the force. Elcometer have therefore developed two solutions to this problem.
