Abstract

PROBLEM TO BE SOLVED: To obtain a water repellent composition excellent in the retentivity of water repellency, the easiness of fall of water drops, etc., by mixing an alcohol with a specified fluorosilane, a siloxane-terminated diol and a hydrolysis catalyst in a specified ratio. SOLUTION: This water repellent composition is obtained by mixing 100 pts.wt. alcohol (e.g. ethanol) with 0.01-5 pts.wt. compound (e.g. heptadecafluorodecyltrimethoxysilane) represented by formula I (wherein R is a monovalent hydrocarbon group; X is an alkoxyl; (m) is 5-9; and (p) is 0-2), 0.01-5 pts.wt. hydroxyl-terminated organosiloxane represented by formula II (wherein R<1> is a monovalent hydrocarbon group; and (q) is 5-50) and 0.001-0.1 pt.wt. hydrolysis catalyst (e.g. hydrochloric acid). Glass treated with the obtained water repellent composition shows good water repellency, and water drops formed on its surface can easily fall to keep visibility through the glass good. Therefore, this composition is useful as a water repellent for especially an automotive window glass.

2. Description of the Related Art
As a water repellent agent for glass, a composition in which polydimethylsiloxane is dispersed in a solvent such as alcohol is commercially available. However, these compositions have a problem that the persistence of water repellency is not sufficient, and on the other hand, a water repellent composition containing a fluoroalkylsilane or the like has been proposed. For example, a method of forming a water-repellent coating on a substrate such as glass using two or more kinds of fluoroalkyl group-containing alkoxysilanes having different molecular chain lengths (see JP-A-5-96679), silane having a fluorine atom. A method of coating a glass surface with a compound to impart water repellency (JP-A-5-96681).
(See Japanese Patent Laid-Open Publication No. 2003-242242), a method of imparting water repellency by forming a mixture of a water repellent agent such as a fluoroalkyl group-containing alkoxysilane and an aqueous solution of hydrosilicofluoric acid saturated with silicon dioxide on the surface of a base material (Japanese Patent Laid-Open No. Hei 10 (1999) -242242). 5-97474 and 5-9747
No. 7, JP-A-5-97478), a water repellent agent comprising a polyfluoroalkyl group-containing silane compound or a partial hydrolysis-condensation product of the compound and a metal alkoxide (JP-A-58-172245, JP-A-58-172245). 64-68477, JP-A-5-
-345641), a film-forming agent composition (see Japanese Patent Application Laid-Open No. 5-311121) for imparting water repellency, which is composed of an onoganosilazane copolymer having a perfluoroalkyl group and an organic solvent (see JP-A-5-311121). , A water repellent agent comprising alcohol and water (see JP-A-5-311156), a partial hydrolyzate of a fluoroalkylsilane and a metal alkoxide, a water repellent agent containing water and an acid catalyst (JP-A-5-31156). 319867) and the like are known. However, in the water repellent using the fluoroalkyl group-containing silane shown in these, it is necessary to use a special solvent, heat treatment is required, or post-treatment such as wiping is required. There was a problem. The resulting water-repellent treated glass repels water to form water droplets, and the water repellency evaluated from the contact angle is good, but the water droplets do not always fall sufficiently from the treated glass surface, and the treated glass is When it is used as a window glass of, a further improvement is desired in order to obtain a good visibility.

The component (B) of the present invention is a fluoroalkyl group-containing alkoxysilane represented by the general formula (1). In the formula, R represents a monovalent hydrocarbon group, and examples thereof include an alkyl group such as a methyl group, an ethyl group, a propyl group, and a hexyl group. Above all, a methyl group is particularly preferable because the resulting coating has good water repellency. preferable. X represents an alkoxy group,
Methoxy group, ethoxy group, isopropoxy group, n-propoxy group, n-butoxy group and the like are exemplified, and among them, the curability of the composition, the methoxy group and the ethoxy group are preferable because the resulting coating has good water repellency, A methoxy group is particularly preferable. In the fluoroalkyl group of the component (B), m is an integer of 5-9. When m is 5 or more, the surface energy of the coating film formed on the base material becomes lower, so that the film exhibits excellent water repellency. When m is larger than 9, the boiling point of the fluoroalkylsilane used in the water repellent agent becomes high, which causes a problem in the synthesis of the fluoroalkylsilane. Further, in the component (B), p is an integer of 0 to 2, and is preferably 0 or 1 because the resulting coating has good water repellency.

If the amount is more than 5.0 parts by weight, it becomes difficult to apply the composition uniformly on the surface of the glass substrate, and an excessive silane component remains on the glass surface, which requires post-treatment such as wiping, which is not preferable. Also 0.01
If the amount is less than the weight part, it becomes difficult to obtain good water repellency by one treatment.

If the amount is more than 5.0 parts by weight, the durability of the fluoroalkylsilane becomes difficult to appear and the adhesion to the glass substrate becomes poor.If it is less than 0.01 parts by weight, only the properties of the fluoroalkyl group-containing alkoxysilane are developed. However, the surface of the substrate has too strong water repellency, and the water drops adhere to the surface without falling, resulting in poor visibility.
