Fluorosurfactant Selection Guide

FluorN surfactants are highly effective fluorinated surface active agents based on perfluoroalkyls (PFA) and perfluoropolyethers (PFPE). These fluorosurfactants are especially designed to provide rapid spreading, wetting and leveling performances to a broad range of water and solvent borne systems such as detergents, paints and varnishes, inks, waxes and floor polishes. Fluorosurfactants can realize low surface tension with smaller amounts of material compared with hydrocarbon or silicone surfactants. Fluorosurfactants have a lower critical micelle concentration and a lower critical surface tension than hydrocarbon or silicone surfactants.
