3M™ Novec™ Fluorosurfactant FC-4432 is a non-ionic polymeric fluorochemical surfactant
belonging to a class of coating additives which provide low surface tensions in organic
coating systems that are best obtainable with fluorochemicals. Novec FC-4432
fluorosurfactant is an excellent wetting， leveling and flow control agent for a variety of
water-borne， solvent-borne， high solids， and radiation curable organic polymer coating
systems. Novec FC-4432 fluorosurfactant is soluble and compatible with most polymers
and continues to be active throughout the drying or curing process. When used in waterborne
polymer systems， Novec FC-4432 fluorosurfactant tends to reduce the
aqueous/organic interfacial tension and remain surface active in the organic portion of the
polymer system.
Novec FC-4432 fluorosurfactant is the first in a new line of fluorochemical surfactants from
3M based on perfluorobutane sulfonate (PFBS). PFBS refers collectively to
perfluorobutane sulfonyl compounds including perfluorobutane sulfonates. 3M believes
PFBS-based surfactants， with only four perfluorinated carbon atoms， offer improved
environmental properties.
