TAmp Posted September 15, 2017 Share Posted September 15, 2017 Hello to everyone!Several resins are used in pyrotechnics as binders and fuels. But iam wondering if colophony (pine resin) can be used as a binder? I had read about using as a fuel but there are only rarely informations as a binder.Thanks in advance!TAmp Link to comment Share on other sites More sharing options...
OldMarine Posted September 15, 2017 Share Posted September 15, 2017 I just checked some other sites and it is never mentioned as a binder. Most mentions sgrs as the preferred binder in those comps. 1 Link to comment Share on other sites More sharing options...
AustralianPyromaniac Posted September 16, 2017 Share Posted September 16, 2017 It looks to be "sometimes used as a binder" http://pyrodata.com/chemicals/Colophonium so in theory, it should be possible to adapt as a binder, but you would have to work it into your comps and experiment to get it working (Assuming this information is accurate). It seems Bengal Blue #2 uses it, but it's not a star so who knows if it would work when blown from a shell. Alternatively, the other example given is 'Red fire composition #4' however, similarly, this isn't a star comp so who knows. Do some experiments and report back to us TAmp!
