Surface-active agents

[Polydimethylsiloxane (PDMS)]

Siloxanes are surface-active agents, and this characteristic makes them widely used as antifoam agents in wastewater treatment plants, in laundry detergents, in food and drug synthesis fermentation processes, and in a wide variety of personal care products. Besides their use as antifoam agents, siloxanes are used also as light-duty lubricants and mold-release agents in car polishes, many household products, metal protectants, and moisture-proofing agents. PDMS is also used as a dielectric coolant in power transformer in place of PCBs. (ref. ID; 2169)
