DeFelsko® Powder Checker

This simple, easy-to-use gage measures the thickness of applied dry coating powder  ...before it's been cured!


Check Powder thickness with Powder Checker before curing to help ensure correct cured film thickness the first time through the line.  Avoid stripping and re-coating which can cause problems with adhesion and coating integrity.

SIMPLE OPERATION

  1. Push the Powder Checker perpendicularly into the dry powder so that the two stand-offs (end tabs) on both sides of the teeth rest firmly on the substrate.
  2. Drag the Powder Checker along the surface of the coated part for at least 1 centimeter.
  3. Remove the Powder Checker from the surface and examine the marks left in the powder.

    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 gage may affect the characteristics of the cured film.
