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

- Ideal for set-up and quality control
- Works on a variety of part sizes, shapes and substrates such as metal, plastic, wood, glass and more
- Easy to carry; convenient shirt pocketsize
- Available in microns (metric) and mils (imperial)

- Broad stand-offs on both sides of teeth help keep gauge perpendicular to surface when measuring
- Rugged aluminum construction for long gauge life and static control
- Precision gauge; manufactured to a tolerance of ± 5 microns or ± 0.0002 inch
- Protective leather pouch included with each gauge
- Push the Powder Comb perpendicularly into the dry powder so that the stand-offs (end tabs) on both side if the teeth rest firmly on the substrate.
- Drag the Powder Comb along the surface of the coated part for at least 1 cm.
- Remove the Powder Comb 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 3 & 6 mil teeth both make lines and have powder clinging to them, but the 9 mil tooth does not. The uncured powder thickness is determined to be between 6 & 9 mils. (Table below illustrates further).
|Powder Comb Models ||Height |
|Model 1 (mils) ||3 ||6 ||9 ||12 |
|Model 2 (mils) ||10 ||15 ||20 ||25 |
|Model 3 (mils) ||20 ||30 ||40 ||50 |
|Model 4 (µm) ||75 ||150 ||225 ||300 |
|Model 5 (µm) ||250 ||375 ||500 ||625 |
|Model 6 (µm) ||500 ||750 ||1000 ||1250 |
Note: Most powders cure to approximately 50% of their dry thickness. Marks left by the gauge may affect the characteristics of the cured film.
