General
Description
A functionalized polyethylene copolymer based thermoplastic
powder coating designed for maximum mechanical
performance, impact resistance and UV-stability. Polyarmor®
G17 Texture is a non-skid protective coating.
Surface Preparation
Chemical Pretreatment
- Multi-stage phosphate conversion coating may be used Mechanical Preparation- (SSPC-SP6) 2-3 mil (50-75µm) anchor profile using
clean, sharp edged blast media
NOTE: Properly preparing parts before powder coating is
essential for a quality finish. This includes cleaning,
rinsing, drying and insuring the substrate surface is free and
clear of any contaminates.
Fluidized Bed
For fluidized-bed dipping, preheat
parts to 450° F (230°C) adjusting for part thickness.
Dip parts in fluidized-bed
of Polyarmor® G17 Texture
for 8-10 seconds. Allow excess powder to stand for 1 minute
then carefully blow off
the excess material. Post bake coated
part @380° F - 400° F (193 - 205°C) for 3 –
4 minutes. Important: Polyarmor®
G17 Texture is designed to texture on the HORIZONTAL surface
of the part. There will
be slight texturing on vertical surfaces.
For best results, do not water quench cool Polyarmor® G17
Texture.
Electrostatic Deposition
Polyarmor® G17T can be applied
via electrostatic deposition with or without pre-heat. When
not using pre-heat,
the powder should be applied to achieve
a thickness of 8 – 10mils (203 - 254µm). Recommended
voltage setting
when using Corona equipment is 40 –
60 kv. Post-baking at 350 - 425°F (175 - 220°C) for
5 to 10 minutes
depending on metal thickness, or until
desired flow out is achieved. For preheated parts, the recommended
preheat
temperature is 400°F (205°C).
Deposit Polyarmor® G17 8-12mils (203 – 300µm)
or higher if desired. For
improved surface finish, parts may
be post-baked for a short period of time if necessary. Times
and temperatures in
the oven will depend on configuration
and thickness of the part.
No Cure Time
Thermoplastic powder coatings
need only be heated enough to flow out the coating, nothing
more. Overheating
may cause degradation or embrittlement
of the coating. Coating may be put into service when cooled.
