Accroides resin (Gum Yakka) is an organic orange powder derived from the Xanthorrhoea trees. The Resin has a complex chemical nature and is composed of benzoresinotannols, benzoresorcinol and traces of cinnamic acid as well as many other materials. The colour is from picric acid and tannin.
Applications
Pyrotechnic Fuel – Accroides resin is popular in Europe and Australia as an alternative to shellac. It is cheaper and also burns slightly faster, helping maintain combustion of fast moving stars. The organic nature of the resin means it do not colour the flame, making it suitable for coloured fire compositions.
Varnish / Dye - Dissolved in alcohol, it can be used as an alternative to the more expensive shellac or copal, the finish is hard and highly resistant to oils, but can be brittle. Heating the resin causes it to cure, becoming completely insoluble. Accroides resin has good lightfastness when used as a dye, it can be mixed with lacquers to give a tougher finish than pure accroides resin. It has also been used in the past to dye soap and leather.
