Short Perfluorinated Chain Fluorosurfactant
Advantages
WFS-278 is a water-solvent soluble, ethoxylated non ionic fluorosurfactant (solvent free) that effectively reduces surface tension at very low concentrations. It cannot breakdown to PFOA in the environment.
- High property in terms of dynamic surface tension, allowing the coating formulations to reach rapidly the low values of static surface tensions
- Stable in both acidic and basic conditions,
Perfect for organic polymer and water-solvent based paint and coatings. It can be used as an emulsifying agents.
Meets the goals of the voluntary U.S. EPA
