[QUOTE="MagnumManiac, post: 1980741, member: 10755"] I find this interesting, in most cases, it is the ether, alcohols and solvents evaporating that decreases the energy of the powder over time. I have seen IMR take a quantity of the first batch ever made of IMR4064 from a container filled with powder that is covered with WATER. They dry it out[I] [/I]and test it against newer batches to see if the recipe stays the same. If powders were hygroscopic, why would IMR store the powder in water? I have never seen any real evidence that powders are hygroscopic, only anecdotal tales of such. None of the MSDS mention moisture other than the solvents used. Yes, there is a moisture content %, but no where does it say this increases with exposure to air. It is the solvents degrading that causes powder to go bad, not moisture. Anyway...battle on. Cheers.
