Capstone® Fluorosurfactant FS-31

Capstone® fluorosurfactant FS-31 is a non-ionic fluorosurfactant. It provides exceptionally low surface tension in aqueous or solvent-based products, enabling better wetting, spreading, leveling, and other beneficial properties. It is VOC- & APEO-free, non-flammable and is compatible with additives and resins of any ionic class. Even at very low concentrations, it can deliver tremendous wetting power. It is stable in acidic, basic, brine and hard water environments, making it easy to formulate into a variety of systems, based on short chain molecules that cannot break down to PFOA in the environment. It provides wetting and levelling, good re-wet characteristics in multi-coat applications, reduces cratering and provides faster spreading, compatible with hydrocarbon surfactants when used in water-based floor finishes, waxes and polishes. Improves wetting in wood coatings. Suggested use rates are 0.01–0.1% active ingredient in aqueous-based paints. It has a shelf life of 5 years.
