Powder thickness with Powder Comb 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.
- Ideal for set-up and quality
- 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) or mils (inch)
- Broad stand-offs on both sides of
teeth help keep gage perpendicular to surface when measuring
- Rugged aluminum construction for long
gage life and static control
- Precision gage; manufactured to a
tolerance +5 microns or +0.0002 inch
- Protective leather pouch included with each
- Push the Powder Comb
perpendicularly into the dry powder so that the two stand-offs (end tabs) on
both sides of the teeth rest firmly on the substrate.
- Drag the Powder Comb
along the surface of the coated part for at least 1 centimeter.
- 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 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)
Most powders cure to approximately 50% of their dry thickness. Marks
left by the gage may affect the characteristics of the cured film.
