Powdercoating Problems and Questions

[Avi Meron]

Brother Jay,
I did a lot of powder coating in my life, for all kinds of
things...............
The only reason powder coating uses an electrical charge is to keep the
powder, fine plastic ground "to flower like substance" is to hold the
material on the part!  The baking of the plastic is what keeps it on the
part!!!!!!!!!!!!!!!!!!!  If you could hold the powder on the part with any
other means, it would still work the same exact way!!!!!!!!!!!!!!!!!
It does not bond to the part in any other way.  The electrical charge is
there only to allow it to stay till it's baked!  There is NO chemical
reaction in any way.....................why would there be?...............

As you know, "plastic" is heat sensitive and can burn and peel, so what's
there to stop it from doing it if the heat is really great? Your PC parts
don't see the heat our engines do.............agree? So it become one, it is
just bonded to the part in most aggressive way, melted on!  There is NO
other magic involved!

Take care,
Avi

Todd- I just went to China/Taiwan to learn about powdercoating and anodizing
last week and from what I learned, powdercoating if done right should
definitely not come loose. The reason for this is because powdercoating is
electronically embedded into the material with positive and negative
charges,
and is not a surface paint. It actually becomes one. We then took some
recently PC parts and banged them as hard as we could against the cement
floor, and never saw any flaking of any.
