Abstract
A functionalized silicone with perfluorinated polyorganosiloxanes (POS) Rf is used to produce coatings with low surface energy and improved adherence to supports. The compositions include a group POS A bearing, per molecule, bis-perfluoromalonate grafts Gf, functional radicals Fa of the amine (HALS) fa1, epoxy fa2, (poly)ether fa3, carboxy fa4 type, and optionally alkyl groups Galk. The invention is useful for producing soil release coatings for textiles.
