WHAT IS POWDER
COATING?
The WAI Powder Coating System effectively puts one more durable,
simple finishing option within the reach of anyone who wants it. Powder
coating works by electrostatically applying a powder to metal (and
some-non-metal) surfaces. The coated piece is then heated in a
standard non-food prep. electric oven at 400°F for approximate 30
minutes. The resulting finish looks like paint but is more durable and
scratch-resistant.
Powder coating is the process of
electrostatically spraying pulverized
particles of plastic (usually polyester
or polyurethane) onto a clean
metal substrate (the part to be coated).
The
applied powder is then heated (cured) at a temperature of 400°F
peak metal
temperature for 10-30 minutes.
Once the part has been cured for the proper
time, and is cool to the
touch, the part is ready to be placed into
service.
Powder coating offers superior durability and is very resistant to
corrosion, cracking, UV rays, scratches, grease, and most
chemicals.
Powder coating easily turns unattractive parts, into
beautifully
coated works of art!

HOW TO POWDER
COAT
1. Properly prep your
piece:
You must remove any corrosion or previous coatings before
powder coating. Just as you would prep the part for a high
quality
paint job. Corrosion can be removed with abrasive
blasting, wire brush
or chemicals. Pervious coatings can easily
be removed with liquid paint
stripper
2. Properly clean your piece:
After you have removed any
corrosion or coatings
thoroughly wipe down the part with lacquer
thinner
or acetone to completely remove any
residual grease or
oils
3. Masking:
You must mask any areas where you do not want powder.
Powder is very durable and therefore it is very tough to
remove. The supplied tape is used to mask areas and the
plugs will
mask any threaded holes.
NOTE: The masking tape and plugs are applied before
powder
application and removed after the oven cure and cool
down.
TIP: Tip mask large areas you can use aluminum foil along with
the masking tape.
4. Part hanging::
Parts can either be hung
from below the oven rack or set on
top. Just as with liquid coating if
any area of the part touches
the oven rack lit will leave a mark, so
you best finish is
obtained by hanging below the rack with the supplied
hooks.
TIP: You can also use un-coated coat hangers or steel wire to
hang parts
5. Spraying
Powder application is very simple and
straightforward. Simply
fill the powder cup with your desired color of
powder and spray!
6. Curing
The powder must be heat cured to transform
it from a solid
powder (similar to flour) into a gel state that allows
the particles
to melt and adhere to the surface. This operation MUST be
performed in a non-food prep oven. The oven is preheated to
400F; once the part is powder coated carefully move the oven
rack
into the oven. Check the part every 5 minutes until the
ENTIRE part has
turned from a dry powder state to the gel
state (this is easily
identified as the powder will be glossy and
look wet). Once this
happens set your timer for 20 minutes.
Once cured allow the part to
cure and put back in service
TIP: Small toaster ovens can be obtained for
about $20 or
even less at flea markets. Start with this size and then
keep
your eyes open for associates, friends, etc that are upgrading
their kitchen oven. Once you start powder coating you will
realize
the benefits, ease and want to do larger parts!
What can be powder
coated:
Essentially any metal object that can withstand the 400 F cure
temperature can be powder coated. Objects that have
gaskets,
wires, grease seals, bearings or plastic components
must first be
disassembled to remove these components that
will not with stand the
cure temperature
