For those looking to replace PFAS in their coatings formulations, this article discusses some experiments and data that show how organosilicones compare to PFAS compounds in critical performance criteria such as low surface tension/surface energy, COF, water repellency, oil repellency, stain resistance, and chemical stability.
Over my 33 year career (so far) in organomodified silicones, customers have occasionally asked me for green, natural or sustainable products. The early requests were infrequent, usually for very specific circumstances, and somewhat vague with the askers often uncertain what their choice of terminology meant.
While there may be a tendency to bemoan increased regulations, one can also reflect on the innovation that has been achieved as a result of these perceived and actual constraints.
To comply with VOC regulations, coatings manufacturers have gradually moved away from conventional low-solids, solventborne systems to several emerging technologies, which include high-solids, UV, powder, waterborne and solvent-free systems.1-3
