Re: [Biofuel] methyl ethyl ketone
Correction, Methyl Ethyl Ketone PEROXIDE (MEKP)is used as the hardening agent (Catalyst) in fiberglass. Methyl Ethyl Ketone is like an acetone used for thinning some paints and polyester gelcoats.

Re: [Biofuel] methyl ethyl ketone
hi Zeke. I wasn't really I was in the autoparts store looking for Heet methanol and isopropyl alcohols when I spied the ethylene glycol and while standing there feeling like an outsider (everyone else in the store was going to use the products for its intended purpose) I am beginning to see past the labels and look at the ingredients. So, as I expand my awareness (thanks to this group) I go back to things I read here without being exactly able to recall details while in the aisles of the auto parts store. Vague recollections is about all that come to me and I am barely over fifty. To answer your question, if I haven't in a round about way already, I have no idea why I was asking about ethylene glycol. On an upbeat note this information about propylene glycol is very interesting as I have the coils of radiant floor heaters in my house and as yet have not hooked them up. I am waiting for inspiration to build a boiler for our wood fired space heater. Thanks for making another scratch to itch, I think.
