Fluorosurfactant FC-4430 is a non-ionic polymeric fluorochemical that offers excellent wetting, leveling and flow control in a variety of coating systems. It lowers surface tension and significantly outperforms many hydrocarbon and silicone-based surfactants. In addition, this product can provide stain and dirt pick up resistance by making the coating surface oleophobic.fluorosurfactants, only a very low concentration (typically 0.1% or lower) is necessary to achieve a significant surface tension reduction of a formulation, which for customers means low use levels.
