Check Powder thickness with the Powder Checker Comb before curing to help insure correct cured film thickness the first time through the line. Avoid stripping and re-coating which can cause problems with adhesion and coating integrity.
The powder thickness is between the highest numbered tooth which made a mark and has powder clinging to it, and the
next highest tooth which left no mark and has no powder clinging to it.
Example: The 75 and 150 micron teeth both make lines and have powder clinging to them but the 225 mil tooth does
not. The uncured powder thickness is determined to be between 150 and 225 microns. (see above image)
Note – Most powders cure to approximately 50% of their dry thickness. Marks left by the gauge may affect the
characteristics of the cured film.
