Abstract:
1. A winter precipitation barrier composition consisting of, based on a total weight of the winter precipitation barrier composition: about 55 to about 99.9 percent by weight of a monoalcohol; and about 0.01 to about 10 percent by weight of a reactive silane, wherein the reactive silane is selected from the group consisting of: wherein n is a number from 1 to 3, R l is a linear, branched or cyclic, substituted or unsubstituted C 1 -C 30 alkyl, C 2 -C 30 alkenyl, or C 6 -C 36 aryl, alkaryl, or aralkyl group, and X is F, Cl, Br, or I; an alkoxysilane or aminosilane having the formula (II): wherein the alkoxysilane or aminosilane comprises no Si—Si bonds; each R 2 -R 5 can be the same or different; two or three of R 2 -R 5 are of the formula OR 6 or NR 7 R 8 ; the remaining R 2 -R 5 are independently linear, branched, or cyclic, substituted or unsubstituted C 1 -C 30 alkyl, C 2 -C 30 alkenyl, or C 6 -C 36 aryl, alkaryl, or aralkyl groups that can optionally comprise heteroatoms that are not silicon; R 6 can be a linear, branched, or cyclic, substituted or unsubstituted C 1 -C 30 alkyl, C 2 -C 30 alkenyl, or C 6 -C 36 aryl, alkaryl, or aralkyl groups that can optionally comprise heteroatoms that are not silicon; and R 7 and R 8 can be the same or different and can be hydrogen or a linear, branched, or cyclic, substituted or unsubstituted C 1 -C 30 alkyl, C 2 -C 30 alkenyl, or C 6 -C 36 aryl, alkaryl, or aralkyl groups that can optionally comprise heteroatoms that are not silicon; a compound having the formula (III): wherein R 6 and R 8 are independently halogen or linear, branched or cyclic, substituted or unsubstituted, C 1 -C 30 alkoxy groups and R 7 is a linear, branched, or cyclic, substituted or unsubstituted C 1 -C 30 alkyl, C 2 -C 30 alkenyl, or C 6 -C 36 aryl, alkaryl, or aralkyl group that can optionally comprise heteroatoms that are not silicon; and a combination thereof; an auxiliary compound selected from the group consisting of silicone oils, fluorinated polyether diols, a combination of the foregoing auxiliary compounds, or a combination of the foregoing auxiliary compounds and glycols; and optionally an additional component selected from the group consisting of a humectant, a pH buffering agent, a coloring agent, a dye, a pigment and combinations thereof.
