Andy,

Nice to have that bit of info. Since isopropanol seems to be readily available in varying strengths in the US, the question remains how, if any, does the fact it is an isomer affect its properties when mixed with epoxy? I'm sure that at 90 and 99% it works well but it be interesting to learn further what the reason is for using an isomer of the pure form for medical applications. Something to look into...

Acetone is a great solvent for many things (particularly paint). I just dislike the way it smells.

David.

P.S. LatinRClover, be careful with that methanol. As mentioned, it is a dangerous substance especially if accidentally mixed with hot water. Don't ask...
