Patent ID: 7578877

Claim:
A two-component system for equipping a surface with an oil, water, and dirt repellent coating, the system, comprising: a first sealed vessel comprising a formulation 1; and a second sealed vessel comprising a formulation 2; wherein: the formulation 1 comprises at least one carbosilane selected from the group consisting of: fluoroalkylsilanes of formula (I) R 1 —Y u —(CH 2 ) 2 Si(CH 3 ) q (R 2 ) 3-q (I) wherein R 1 is a mono, oligo, or perfluorinated linear, branched, or cycloalkyl group comprising 1-13 carbon atoms or R 1 is a mono, oligo, or perfluorinated aryl group, wherein Y is a —(CH 2 ), O or S group, wherein u is 0 or 1, wherein R 2 is a chlorine atom or an alkoxy group comprising 1 to 4 carbon atoms, and wherein q is 0 or 1; and alkylsilanes of formula (II) R 3 Si(CH 3 ) p (R 4 ) 3-p (II) wherein R 3 is a linear, branched or cyclic alkyl group comprising 1 to 18 carbon atoms, wherein R 4 is a chlorine atom or an alkoxy group comprising 1 to 4 carbon atoms, and wherein p is 0 or 1; the formulation 2 comprises water, an organic or inorganic acid, and at least one solvent or diluent; and the system is configured so that the first sealed vessel and the second sealed vessel can be unsealed and their respective contents mixed together shortly before application to the surface.
