From my experience, 1% lampblack is enough to color the entire world AND
track throughout your house. I've never used over 0.5% - motor was 6".

Thx. We’re going to use 1% with AP and Oxamide; sounds like that will be
plenty to keep the IR from penetrating,

Hi Bill, I'm not sure whether 70% solids will make a difference, but
0.2% in an 80% solids mix seems to work quite well. It's what I used
for PBAN in Experimental Composite Propellant, and it worked well for an
80% solids HTPB propellant as well.

For a non-aluminized solid propellant with low solids loading (70%)
what percentage of carbon black will provide sufficient opacity?
