Strip off paint on ABS
Dear sir,
I want to strip off paint from automotive ABS part (like rear
mirror) for plating on ABS.Would you recommend how to strip off paint
with out or little bit attack on plastic.
Best regard,

Dear sir,
We should know the kind of paint but generally paint removers are
two kinds.
1-based on organic solvent[methylene chloride-xylene...etc]
2-based on caustic strong alkaline to destroy the paint
film[NaOH-S.phosphate....etc]
So until you telling me the kind of paint you use the second type
of removers is more safe.
Thanks,

Dear RAAFAT,
I don't know the type of paint but it is used in automotive
industry. The solvent base strip off paint may be too agressive to
strip off paint on ABS parts.

Prasarn,
What Raafat said is l00% true ... in fact I didn't even know that
there were two types of paint remover. Thanks for the education,
Raafat!
He didn't recommend the first one BECAUSE the standard cement for
ABS happens to be related to methylene chloride ie.
MEK / methyl ethyl ketone [link is to product info at Amazon]. Don't
even consider using it! It will dissolve the ABS very nicely, thank
you!

Dear sir,
It is clear that you don't know the type of paint[polymer] so I
will ask one expert [friend] till that you can use the alkaline
remover [pH>12]. I'm sure paint film will destrued but take care
this will make slightly etched ABS so make one sample first to adjust
the time
Good luck,
