Chemguard S-550-100 is a 100%-active short-chain perfluoro-based ethoxylated nonionic fluorosurfactant.  It provides surface tensions as low as 19 dynes/cm in water at low concentrations and is also surface active in many solvents.  This product has excellent dynamic surface tension properties, allowing rapid attainment of low equilibrium surface tensions. Due to its exceptional surface activity, Chemguard S-550-100 imparts excellent wetting; spreading, leveling, and flow-control properties to various types of water-based as well as solvent-based coating formulations.
