Hi everyone! Might be a dumb question might not lol… Anyways here I go 
!
Is it safe to cut/engrave/forge on though paint that’s vehicular is Acrylic polymer emulsion? With a pigment of Titanium Dioxide (PW6)?
Asking for me? I mean a friend?

I don’t have the answer, but here are two things to consider:
-
A link to a company’s info sheet
-
Titanium is a metal. I don’t know how much of it is in the emulsion, but…it’s a metal.
Not a chemist, so don’t take this as more than a gut feeling.
The pigment is titanium dust. Titanium doesn’t reflect the laser, so I’m going with “safe”.

Isn’t that just acrylic paint?
Titaniuim dioxide is the chemical that makes EVERYTHING white. When I say everything I mean everything. If you have cut white paper, white acrylic or anything else that’s human-made and white then it has TiO2 in it.

I suspect that you would have nearly the success of separating the oxygen from Titanium as from Aluminium. If it was easy folks would have been making Titanium steel swords back when doing so would be more useful than now.

It’s in almost every paint out there - even ones that aren’t white because it’s used for a consistent base that can be tinted & colored more consistently than attempting to create many of the colors out there.
Look at almost any paint can and you should see it referenced. It’s safe to laser.
You do have to keep in mind what it’s on though - so it’d be best not to be lasering it if it’s painted on copper sheeting for instance
