I am researching if this material can be used for a replacement of charcoal in gunpowder. Dont ask.

This was a very helpful video to understand the basics of this polymer. I'm just getting into resin casting and part making, and with a chemistry background, I've been searching for an explanation of the material chemistry. This gave me a bit of a jumping off point. My profession life is in organic chemistry and production but I know I'll remember this video for future conquests.
