enanthate Posted September 27, 2014 Share Posted September 27, 2014 Dear firemakers, I'm looking for a granite-composition that can be bound with acetone/alcohol. Couldn't find anything on Google or Passfire, is this even possible?Feel free to give me an "experimental" comp, and I will post results! enan Link to comment Share on other sites More sharing options...
dagabu Posted September 29, 2014 Share Posted September 29, 2014 (edited) Are you looking for a Zinc composition? I would try phenolic resin or Red Gum as a substitute for the typical binder. Zinc powder, fine 620 Potassium Nitrate 215 Charcoal, airfloat 55 Charcoal, 80-mesh or more coarse 36-40 mesh 55 Sulfur 40 Dextrin 15 Total 1000 I would have search my notes for the replacement value but I think its about 20 6 parts of resin as a sub.

enanthate Posted September 29, 2014 Author Share Posted September 29, 2014 Cheers, I thought I might needed parlon (didn't know RG did such a good job). Will try that today. Would BP + 5% Si do the job for priming? Got plenty of star-batches here, mostly parlon-bound colors, red strobes and now this comp. Is my prime good enough for all of the mentioned? Should I perhaps add a layer of Pinball right on the starcomp? Link to comment Share on other sites More sharing options...
