Abstract: The present invention provides a composition comprising an aqueous dispersion of a fluorochemical compound and a cationic surfactant and wherein the composition further comprises colloidal inorganic particles.

Abstract: The present invention relates to a method of treating a non-woven substrate or textile, comprising the step of applying to said non-woven substrate or textile a fluorochemical composition comprising a fluoropolymer that comprises:(a) between 10 and 97 mole % of units that can be derived from fluorinated monomer selected from the group consisting of monomers according to the general formula: Rf-X—OC(O)—C(R)?CH2 wherein Rf represents a perfluorinated aliphatic group having 3 or 4 carbon atoms, X is an organic divalent linking group and R represent hydrogen or a lower alkyl group having 1 to 4 carbon atoms; (b) between 3 and 75 mole % of units derived from a chlorine containing comonomer selected from the group consisting of vinylidene chloride, vinyl chloride and mixtures thereof; and (c) optionally further units derived from monomers other than a fluorinated monomer and said chlorine containing comonomers; wherein the amount of units (a), (b) and (c) adding up to 100%, whereby said fluorochemical composition i

Abstract: The invention relates to a water and oil repellency imparting composition which comprises:(a) a fluoroaliphatic radical-containing agent; and(b) a cyclic carboxylic anhydride-containing polysiloxane. Additionally, the composition may comprise:(c) an extender and/or a plasticizer. The composition provides water and oil repellent properties and a soft hand to fibrous and other substrates treated therewith.

Abstract: This invention relates to a treating composition containing 0.3 to 30% by weight of a fluoroaliphatic radical containing poly(oxyalkylene) compound, 0.3 to 30% by weight of an anti-soiling agent and 0 to 60% by weight of an environmentally acceptable water-miscible organic solvent and water for the use for imparting excellent water- and oil repellency, stain resistance and dry soil resistance to textiles, carpets, concrete, paper, leather and wool.

Abstract: The invention provides polymers or copolymers which are prepared by the polymerization of the reaction product of a diisocyanate with a perfluoro compound or an epichlorhydrinadduct thereof and (meth)acrylic esters of a three hydroxyl groups containing compound. Furthermore, the invention relates to fluoroacrylic monomers, a process for preparing the polymers or copolymers and a treatment agent comprising the polymers or copolymers of the invention and an environmentally acceptable solvent. Polymers and copolymers of the invention can be used for making textiles, papers, non-woven articles, leather, plastic, wood, metal, stone and cement water and oil repellent.

Abstract: A composition for treating fibrous substrates such as textiles to provide oil and water repellency is provided. The composition comprises a) a terpolymer comprising randomly distributed i) units containing a fluoroaliphatic group, R.sub.f, ii) fluorine-free hydrocarbon units, and iii) units containing silicone and b) a fluorine-containing polymer having isocyanate derived linking groups and blocked isocyanate moieties. Also provided is a method for providing oil and water repellency to a fibrous substrate.
