Powder
Thickness Checker
by DeFelsko

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 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.
Versatility
- 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 pocket
size.
- Available in mils (inch) or microns
(metric).
Quality
- 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 of ± 0.0002 inch.
- Protective leather pouch included with
each gage.
Simple
Operation
- 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. (Unit
is shown full-scale on right when viewed on a 19" monitor at
1024 x 768 resolution).
- Drag the Powder Checker along the
surface of the coated part for at least 1/2 inch.
- 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 3 and 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 and 9 mils (see figure).
