Sorry that was meant to mean 20 & dark Al. I got that information from a friend of mine in the US... there is also a patent regarding the addition of pentaerythritol / T A to aluminum.
Blue Aluminum seems to be a blend of ~ 80 % 80 - 200 mesh atomized Al and ~ 10 % dark pyro Al (like 5413). A small amount of terephthalic acid or pentaerythritol
is added to ensure its safety features - upon heating, the organic substance melts/sublimes and consumes a huge amount of the energy provided to the mixture.
