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.
