A fluorochemical composition to impart water repellency and/or oil repellency to a substrate, the composition comprising one or more condensates of (i) a methylolated amine or a C1-C4 alkoxylated derivative thereof, (ii) a hydrocarbon compound represented by formula (II) and (iii) a fluorinated compound represented by formula (I): Rf—(X1)n—Z1 (I) wherein: Rf is a fluorinated aliphatic group; X1 is an organic divalent linking group; Z1 is selected from the group consisting of hydroxy, thiol, amide or acid groups; and n is 0 or 1; and Rh—Z2 (II) wherein: Rh is a hydrocarbon group having at least 6 carbon atoms and optionally being substituted with 1 to 3 subsituents; Z2 is selected from the group consisting of hydroxy, thiol, amide or acid groups. The invention further provides a method of treatment of a substrate with the fluorochemical composition and a treated substrate.
Method of treatment of a substrate comprising contacting said substrate with a fluorochemical composition comprising one or more condensates of (i) a methylolated amine or a C1-C4alkoxylated derivative thereof, (ii) a hydrocarbon compound represented by formula (II) and (iii) a fluorinated compound represented by formula (I):
A fluorochemical composition comprising one or more condensates of (i) a methylolated amine or a C1-C4 alkoxylated derivative thereof (ii) a hydrocarbon compound represented by formula (II) and (III) a fluorinated compound represented by formula (I):
Method of making a fluorochemical composition comprising reacting in the presence of an acid catalyst (i) a methylolated amine or a C1-C4 alkoxylated derivative thereof, (ii) a hydrocarbon compound represented by formula (II) and (iii) a fluorinated compound represented by formula (I):
