Indusil 139 silicone is an aqueous solution of a silicone polymer modified with organic groups. At temperatures below its cloud point, it is completely soluble in water forming a clear, yellow solution. It possesses a dual functionality: at temperatures below its cloud point it typically stabilizes emulsions and latexes but at temperatures higher than its cloud point it destabilizes them. As such, Indusil 139 silicone is different from typical polydimethylsiloxanes (PDMS) which are not water soluble and which require emulsifiers to produce milky-white emulsions.
