RE: Acetone Substitutes



We have had some success w. NMP (n methyl pyrrolidone) based cleaners.
While they are far from "non-hazardous" (NMP is a reportable chemical)
the very low vapor pressure and easy reclamation (vacuum distillation)
offers some advantage over acetone when it comes to air exposure,
flashpoint, waste and ease of handling.

Searching for the Holy Grail ..... an effective, non haz substitute
for acetone used in equipment cleanup for fiberglass boatbuilders.
Some substitutes being used by Florida boat manufactures with
apparently satisfactory results include propylene carbonate, S-280 and
Super Red. Would be interested in any pros/cons re these three
substitutes or any other successful cleanup solvent.

Thanks
