Claims36
An oligomer of n-propylethoxysiloxanes, comprising from 90 to 100% by weight of n-propylethoxysiloxanes having a degree of oligomerization ranging from 3 to 6.
A composition, comprising an oligomer mixture comprising from 80 to 100% by weight of n-propylethoxysiloxanes having a degree of oligomerization ranging from 2 to 6, together with (i) at least one organoalkoxysilane selected from the group consisting of alkyl-, vinyl-, aminoorganoalkoxysilanes, glycidyl ether-functional and glycidyloxyalkyl-functional alkoxysilanes, fluoroorgano-functional alkoxysilanes, acryloyl- or methacryloyl-functional alkoxysilanes, mercapto-functional alkoxysilanes, sulfane- or polysulfane-functional alkoxysilanes and/or (ii) at least one organosiloxane selected from the group consisting of vinyl-functional siloxanes, glycidyloxyalkyl-functional siloxanes, alkylfunctional siloxanes, methacryloyl-functional siloxanes, fluoroalkyl- and fluoroorgano functional siloxanes, and also corresponding cocondensates and/or (iii) at least one silicic ester and/or (iv) at least one oligomeric silicic ester.
An emulsion, comprising an oligomer mixture comprising from 80 to 100% by weight of n-propylethoxysiloxanes having a degree of oligomerization ranging from 2 to 6, as the oil phase in an aqueous emulsion.
A composition, comprising an oligomer mixture comprising from 80 to 100% by weight of n-propylethoxysiloxanes having a degree of oligomerization ranging from 2 to 6, together with at least one water-dissolved silane cocondensate and/or at least one water-soluble organic fluorine compound and/or at least one water-emulsified silicone wax.
