If you search for "pyrotechnic primes" you might have better luck. You can also get a pretty good idea of the formulation of many commercial dip kits from the MSDS (gotta list all flammable metals and oxidizers) or from the name. For example, H3 is a fireworking formulation by Shimuzu, also used as a dip by some (why???)--chlorate and charcoal only--chlorates don't play well with sulfur and what does BP contain...? As Kurt indicated above, some comps are much more sensitive to friction than others. Chlorate-based notoriously so. Nitrate-based not so much, but generally less aggressive burning, too. Perc-based in the middle. In general... Fuels: Mg too reactive and unstable; Al common and cheap; MgAl sparky hot but a little more expensive; Boron great but very expensive; Zirconium the same & hard to source; charcoal cheap but relatively cooler burning--fine for BP but insufficient for APCP without supplemental metals.
