Disclosed is a method of preventing frost and facilitating removal of winter precipitation relative to a windshield, comprising applying to a windshield a winter precipitation barrier composition. In one embodiment, the barrier composition comprises: a solvent and a silicon containing compound, the silicon containing compound comprising at least one of a reactive silane, a polyalkylene oxide polysiloxane, or a combination of at least one of the foregoing, wherein the reactive silane is at least one of a halosilane having the formulaXSiR&#x2003;&#x2003;(I);an alkoxysilane or aminosilane having the formula a compound of formula(R)Si&#x2014;R&#x2014;Si(R)&#x2003;&#x2003;(III);or a combination comprising one or more of the foregoing reactive silanes. In another embodiment, the disclosed winter precipitation barrier composition comprises a reactive silane and a solvent, wherein the reactive silane is as described above.

Methods of preventing frost formation and facilitating the removal of winter precipitation relative to a windshield and compositions for use therein

Disclosed are windshield washer compositions comprising a nonionic amino-modified silicone-polyalkyl copolymer, said copolymer being water dispersible and hydrophilic. In one embodiment, the disclosed washer compositions are ready to use washer fluids. In another embodiment, the disclosed windshield washer compositions are additive concentrates. Also disclosed is a method of treating a glass surface comprising applying the disclosed compositions to a glass surface. In one embodiment, a suitable glass surface is the windshield of a transportation vehicle such as an automobile.
