COMPOSITION FOR PROTECTION OF PRODUCTS FROM NATURAL AND ARTIFICIAL SMOOTH AND PILE LEATHER AGAINST ACTION OF WATER AND WATER SOLUTIONS OF DE-ICING REAGENTS Russian patent published in 2015 - IPC C14C11/00 C14C9/00 C09K3/18 

FIELD: chemistry.

SUBSTANCE: composition for the protection of materials against the action of water and/or a water solution, contains: a) organic solvent; b) reactionable bifunctional aminosiloxane, which has the general structural formula I: (I) R1-O[-Si(CH3)2O-]n[-Si(OR2)(R10)O-]mR3; c) fluoropolymer, which represents a polymer and/or a copolymer of monomers, which have the general structural formula (II)-(VI), with the following content of monomers counted per the total weight of the polymer and/or copolymer (wt %): (II) R4-O(CH2)2R6 40÷97, (III) R4-OR7 3÷35, (IV) R4-OR8 0÷25, (V) R4-NHCH2OH 0÷15, (VI) CH2-C(R9)Cl 0÷40, where: R1 and R3 independently on each other represent CH3-Si(OCH3)O-[-Si(CH3)(OR2)O-]x, or methyl, R2 represents an alkyl, which contains one, two, three or four carbon atoms, R4 represents a group CH2=C(R5)C(O)-, R5 represents H or methyl, R6 represents an alkyl, which contains, at least, 4 carbon atoms, substituted with one or two fluorine atoms, R7 represents a C1-C40 alkyl with a straight or branched chain, R8 represents hydroxy(C2-C4)alkyl, R9 represents H or C1, R10 represents -R11-NH-R11-NH2, R11 represents an alkylene, which contains two, four or five carbon atoms, x represents an integer number from 10 to 500, m represents an integer number from 1 to 50.

EFFECT: composition possesses high protective activity due to the combination of bifunctional polyogranosiloxanes and fluoropolymers in one means for leather protection.
