powder coat--bike frames

ilaboo said:

been following the posts on painting a bike frame
i taught it appropriate to start a topic on powder coating
kind of new to usenets and am still learning --i stand corrected if this
post is inappropriate.

from what i know about powder coating is that the object to be coated and
the spray gun are electrically attached and a very high volatage applied.
The spray particals then are attracted by opposite polarity and are applied
more consistantly--i do know this is done painting cars.

the part now covered with plastic is then heated to fuse ( melt) the plastic
particles into one coat-there are tons of different powder coatings
available.

i understand that the coating is much more flexible than paint.

i know powder coating costs more

but--i have seen bikes spray painted with hardware spray paint that was
pretty darn good

Powder-coating's more uniform thickness can make some details such as
lugs or embossed text, etc seem over-painted. Regular paint flows to
very thin thicknesses on sharp edges and looks more delicate. And it
is more delicate, too!

Rattle-can paint jobs can look quite good. As with anything, patience
and proper preparation makes the biggest difference of all.

Powder-coat materials may cost more than paint (I don't know) but it
is the labor that costs most in either case. Few people can do the
powder-coat labor themselves, but almost everyone can do the spray-
cans themselves.

PS: Some might say this thread might be better suited to
rec.bicycles.tech, but I personally think it is fine here too.

One other note re: Powder Coating, It's solvent free, no ozone depleting
hydrocarbons evaporating away. The Volume Solids in typical spray cans is
circa 7%-20%, that means that 80% of what you spray out of the can is
solvent (yes, waterborne paints too). That is also why spray cans have such
poor edge retention (creeping away from edges and sharps).

not to sure about this the manufacturing of plastic
is fill of volitile solvents etc--

the end user may think that they are using something enviormental less toxic
but its the manufacturing process where most of the baddies are

take care

anyone klnow about uv cured sealers /paint technology in its relationshiop
to bike painting?

Yabbut, for every mil (micron) or whatever unit of dry film thickness, the
same volume of resin/binder and pigment is required, so as far as
manufacture goes, there is little difference between the solvented and
solventless technologies. The big difference lies in the end user, the
application process. Here is where the the solventless technology is the
clear winner. AND, typically, end users, whether a guy in his backyard shop,
or an autobody, shop has far less environmental controls in place as does
large manufacturing plants with their various recovery systems.

Coatings, in general, while harmful to the environment, to produce and
apply, paradoxically, benefit the environment by limiting or stopping
corrosion of metals and other surfaces which also have their environmental
costs. AND they do this while making the surfaces more attractrive, easier
to clean, identify, visible (hi-vis), amongst many other benefits.

any experience with uv cured paints/sealer?

No experience with UV cured paints. But I will check some sources and run by
my paint guru

let us know what you find out--i have played with uv cured adhesives (
dental stuff) and watchglass glue--fantastic stuff almost
indestructible--used a uv bulb that was for a visulux 2 dental cure
unit--bulb cost !10.00 and you need eye protection
