Chemguard S-550

Chemguard S-550 by Chemguard is a short-chain perfluoro-based ethoxylated nonionic fluorosurfactant. Provides surface tensions as low as 20 dynes/cm in water at low concentrations and is also surface active in many solvents. Has excellent dynamic surface tension properties, allowing rapid attainment of low equilibrium surface tensions. It is a dilute solution composed of 40% active fluorosurfactant in a water, solvent miscible diluent and a short chain C-6 perfluoro telomer. Chemguard S-550 is chemically more stable than typical hydrocarbon surfactants, particularly in the presence of acids, alkalies or heat and excellent replacement for FSO, FS-31, FS-34 and FS-35. Effective at low concentrations of 50-1000 ppm. Typical uses include adhesives and caulks. Its recommended application rates are 0.05% to 0.3% depending upon the formulation makeup.
