hoangtuan Posted January 5, 2019 Share Posted January 5, 2019 (edited) In my hometown, it's hard to find redgum, parlon, Shelac .. I can use resin colophony to make alternative binders. Is it good? https://photos.app.goo.gl/4A7MRh9FsvaxRoLA6 Edited January 5, 2019 by hoangtuan Link to comment Share on other sites More sharing options...
Nitrotitanite Posted January 5, 2019 Share Posted January 5, 2019 You can tie your stars without problems dextrin or SGR the latter is easier to make at home than just the rice flour or grind the same. Link to comment Share on other sites More sharing options...
OldMarine Posted January 5, 2019 Share Posted January 5, 2019 (edited) I don't think the pine rosin will work very well as a binder. Colophony is just that aerated so I wouldn't think it would work as anything other than a fuel.Aren't you in Vietnam? Soluble Glutinous Rice Starch should be available everywhere.

hoangtuan Posted January 7, 2019 Author Share Posted January 7, 2019 (edited) ok. Detrinx I have a lot. how much is the ratio of redgum and detrinx replacement? 1-1 is that? Edited January 7, 2019 by hoangtuan Link to comment Share on other sites More sharing options...
Nitrotitanite Posted January 7, 2019 Share Posted January 7, 2019 I use about 4% of the total or added to the complete mix is enough to make the stars as hard stones, make sure they are dry. The red rubber mostly serves to slow down the combustion in compositions with strong oxidizer or high amounts. Maybe you could try using the resin at small percentages always with dextrin as a slow motion in fast compositions. Link to comment Share on other sites More sharing options...
