Hello. I am turning some transparent polycarbonate rods (1" thick) and shaping
them into hollow shells to each house a lamp unit. To evenly distribute the
lamp nicely, how can I frost the outside of the polycarbonate ? Sandblasting ?
Definatly wouldn't be sand blasting although blasting with soda might work.
Sand would be way to aggressive and generates heat, not what plastics want
The solvent used to 'weld' acrylics produces a frosted appearance until you
buff it out, but not sure how evenly you could make it look. To try it you
would have to pour or spray it on, certainly don't rag it or brush it on.
When I have done projects, anywhere I ran too much liquid and it ran out
onto the project it dried with a frosted look. If I tried to wipe the
excess off I made a hell of a mess with lint etc, found it best to leave it
to dry then buff it off.
My only other thought would be using 400 grit wet/dry (black carbide paper).
It leaves plastics very white but smooth.
I have made a couple of lamps using plexiglass. I started with clear
plexiglass and then sanded it on one side with my random orbit sander
with some fine (220 I think) sandpaper. It "frosted" it nicely. You
might want to try some tests on scrap.
