Title (EN) COMPOSITIONS COMPRISING FLUORINATED POLYETHER SILANES FOR RENDERING SUBSTRATES OIL AND WATER REPELLENT
(FR) COMPOSITIONS COMPRENANT DES POLYETHER SILANES FLUORES SERVANT A RENDRE DES SUBSTRATS OLEOFUGES ET HYDROFUGES
Abstract: front page image
(EN)The present invention provides composition for treating a substrate comprising a homogeneous mixture of:(a) a fluorinated polyether silane of the formula:R¿f??1¿-[-Q-SiY¿3-x?R?1¿¿x?]¿y? (I)wherein R¿f??1¿ represents a monovalent or divalent polyfluoropolyether group, Q represents an organic divalent linking group, R?1¿ represents a C¿1?-C¿4? alkyl group, Y represents a hydrolysable group; x is 0 or 1 and y is 1 or 2;(b) an organic or an inorganic acid;(c) water and(d) an organic solvent.The invention further provides a method of making such a composition and the use thereof to treat substrates to render them oil and water repellent.
(FR)La présente invention concerne une composition permettant le traitement d'un substrat, ladite composition comprenant un mélange homogène de: (a) un polyéther silane fluoré de formule R¿f??1¿-[-Q-SiY¿3-x?R?1¿¿x?]¿y? (I) dans laquelle R¿f??1¿ représente un groupe polyfluoropolyéther monovalent ou divalent, Q représente un groupe de liaison divalent organique, R?1¿ représente un groupe alkyle en C¿1?-C¿4?, Y représente un groupe hydrolysable, x vaut 0 ou 1 et y vaut 1 ou 2; (b) un acide organique ou minéral; (c) de l'eau; et (d) un solvant organique. Cette invention concerne également un procédé permettant la préparation d'une composition de ce type et son utilisation pour traiter des substrats afin de les rendre oléofuges et hydrofuges.
