Chemguard S-111 is a short-chain perfluoro-based amphoteric fluorosurfactant of the alkyl amine oxide type. It provides surface tensions as low as 15 dynes/cm in water at very low concentrations. It also has excellent dynamic surface tension properties, allowing for rapid attainment of low-equilibrium surface tensions. Chemguard S-111 imparts excellent wetting, spreading, leveling, and flow-control properties on various types of water-based as well as solvent-based systems. Its extremely low equilibrium surface tension, in conjunction with excellent dynamic surface tension properties, make it ideal for coating formulations designed for difficult-to-coat, low-surface-tension substrates. Its amphoteric nature allows S-111 to be unsusceptible to the differences in pH, which provides excellent hard water resistance.

S-111 is an ideal replacement for DuPont Zonyl* FS-510 and DuPont Capstone* FS-51.
