Powder
Coating
Thickness Checker
by DeFelsko

This
simple, easy-to-use gauge 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. |
Versatile
- 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).
