Gum incendiaries

Gum Incendiaries, such as 8% rubber soln in benzene, proved to be (when used in incendiary bombs) about K as effective on the wt basis as magnesium bombs. Being a sticky material, gum incendiary proved to be particularly suitable for use in scatter bomhs. 

SDO (Synthetic Drying Oil). A commercial polymer of acetylene (such as SDO-80) which was evaluated as an incendiary mixt component during WWII. A typical mixt contg 1 p of SDO-80 was mixed with 2p of Na nitrate, and the material was exposed to the air with occasional stirring until it had absorbed sufficient oxygen (about 64% of its wt) to form a sticky brown-colored gel. The gel, when ignited, gave a burn time of brief duration and little incendiary value. It was considered to be about 1/10 as effective as a Mg bomb and 1/5 as effective as a gum incendiary mixt of that era. Its performance was comparable to that of thermite Refs 1) L.F. Fieser, OSRD 173 (1941)...
