摘要
Sol for forming sol-gel layer on the surface of the substrate, comprises organometallic compound of zirconium, aluminum or titanium at 3-20 wt.%, preferably 7-13 wt.%(e.g. 10.8 wt.%); organosilane compound at 5-40 wt.%, preferably 15/20-30 wt.% (e.g. 22 wt.%); an acid or base, glycol or ethoxyethanol compound at 1-10 wt.%, preferably 2-8 wt.% (e.g. 5 wt.%); and demineralized or distilled water 100 wt.%. Independent claims are included for: (1) a kit comprising a first container containing first liquid part having an organometallic compound, an acid or base, glycol or ethoxyethanol compound and water, and a second container containing second liquid part having organosilane compound; (2) a method preparing a sol-gel layer on a substrate surface comprising depositing the sol on the surface, and drying the obtained sol-gel layer; (3) a substrate comprising the sol-gel layer; and (4) a method of preparing coated surface comprises coating layers on the surface of the substrate, where at least one of the layer is the sol-gel layer.
