<p>[QUOTE=&quot;calcol, post: 26708316, member: 77639&quot;]THF is not that hard to obtain as it doesn’t have the restrictions of chlorinated hydrocarbons.&nbsp; About $50 per liter in small quantities. It’s the main solvent in most PVC cements. If you’ve cemented plastic pipe, you’ve sniffed it.&nbsp; I’ve used it to remove PVC residue from coins, and it worked really well.&nbsp; It is just as flammable as acetone though.&nbsp; For most purposes, stabilized THF should be purchased.&nbsp; Over time and with exposure to air and light, non-stabilized THF can form potentially explosive peroxides. Do not try to repurify used THF by distillation or other means; the repurifying process may remove the stabilizer.&nbsp; Not highly toxic, which is why it can be part of PVC cement.&nbsp; As long as small quantities are used carefully in a well-ventilated area, it’s not necessary to use a fume hood.&nbsp; Have never tried to dissolve polymethacrylate with it.&nbsp; Mike[/QUOTE]</p><p><br /></p>
