30-90% of a trialkoxysilane of Formula (I);
wherein R1 of Formula (I) is selected from the group consisting of linear, cyclic or branched C12-30 alkyl, C12-30 alkenyl and C12-30 alkylaryl groups; and
wherein R2, R3 and R4 of Formula (I) are selected independently from the group consisting of linear, cyclic or branched C1-6 alkyl, C1-6 alkenyl, C1-6 isoalkenyl, and C3-12 oxime forming groups; and
10-70% of a polysiloxane of Formula (II)
wherein R1, R2, R3, R4, R5 and R6 of Formula (II) are selected independently from the group consisting of H, OH, linear, cyclic or branched C1-18 alkyl, C1-6 alkenyl, C1-6 alkoxy, C1-6 aminoalkyl, C1-12 vinyl alkyl; C6-18 aryl, C3-18 epoxy-forming groups and di(C1-6 alkyl)hydrogensilyl;
wherein A is independently O or C1-6 alkyl;
wherein B is independently Si(R1)(R2) or R1;
wherein x1 ranges from 1 to 3000 inclusive;
wherein x2 ranges from 0 to 500 inclusive;
wherein x3 is either 0 or 1;
wherein x4 is either 0 or 1;
wherein x5 is either 0 or 1;
wherein x6 is either 0 or 1;
a catalyst which accelerates the reaction between Formula (I) and Formula (II), the catalyst selected from the group consisting of KOH, NaOH, HCl, C1-16 alkylbenzenesulfonic acids, a C1-6 trialkoxy silanes, a C1-12 alkylamines, C1-12 alkanoic acids, C1-12 alkanol, organotin compounds, organotitanate compounds and organozirconate compounds; and
wherein the composition having no added perfluorinated compounds and the weight percentages of all added components above totaling 100% of the weight of the composition; and further
wherein the composition exhibits both water-resistant and oleophobic characteristics.
