Chemguard S-559 is a 40%-active short-chain perfluoro-based ethoxylated nonionic fluorosurfactant.  It provides surface tensions as low as 22 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-559 imparts excellent wetting; spreading, leveling, and flow-control properties to various types of water-based as well as solvent-based coating formulations. 

S-550 is an excellent replacement for competitive products currently offered. Contact Chemguard for recommendations.
