I’ve got a 3D printed project, and went over it with a couple of airbrushed coats of a 50/50 mix of Tamiya X-35 (their alcohol-based acrylic semi-gloss) and Mr Color Levelling Thinner. As far as I can tell, it looks good so far, but now the room next to the one I sprayed in smells of solvent a few hours later, despite extractor fans running. I knew the lacquer thinner was nasty, so bought a respirator, and haven’t been in the room with the model without it (hence only knowing that the next room stinks), but would like to know when I won’t need it anymore. The best I’ve been able to find with Google is the ten-minute touch-dry time, but I’m assuming the VOCs will take longer to be entirely gone.
What’s bad is that as long as you can smell it there’s some VOC’s but aren’t there VOC’s a little after it that aren’t great even if not noticeable?
