TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: An additive (up to 20 wt.%, preferably 0.1-2.5 wt.% each based on the solid amount) is added. A coloring agent (up to 50 wt.%, preferably 0-10 wt.% each based on the solid amount) is added. The coating agent with a layer thickness of 5-60 mu m, preferably 10-15 mu m is applied. The metal alkoxide comprises titanium alkoxide, preferably titanium butylate, titanium propylate or titanium isopropoxide, zirconium alkoxide, aluminum alkoxide or tin alkoxide, where each of the metal content amounts to 1-50 wt.%, preferably 1-30 wt.%. The metal pigment comprises zinc, aluminum and/or magnesium and their alloys. The solvent is water, alcohol, protic or aprotic solvent, preferably toluene, butyl glycol, xylene or isopropanol. A fuel gas comprising propane, butane, ketones, ethers, carbon dioxide, nitrogen or chlorofluorocarbons, or laughing gas is provided during the use of a coating agent that cures at room temperature in the form of the aerosol spray. A dilution with a solvent or solvent mixture to the solid content of 2-40 wt.%, preferably 5-15 wt.% takes place during the use of a coating agent that cures at room temperature in the form of the aerosol spray. A dilution with a solvent or solvent mixture to the solid content of 25-75 wt.%, preferably 40-60 wt.% takes place during the use of a coating agent that cures at room temperature in the form of the color paint. The catalyst (1-10 wt.%, preferably 1-5 wt.%) is added. The catalyst comprises Lewis acids, Lewis bases, organic acids and bases, inorganic bases, functional silanes or amino silanes, preferably inorganic acids comprising sulfur or phosphoric acid, phosphates or blocked phosphates. The additives comprises matting agents, flow additives, slip additive, adhesion additives, flexibility additives or anti-settling agents, preferably Aerosil (RTM: Fumed silica), hydro- and oil repellent additive, drying agents, inhibitors or hydrophilicizing additive. The colorant comprises inorganic and organic pigments, titanium dioxide, carbon black or iron oxide. EXAMPLE - Fine leaflet-shaped zinc powder (100 g) and leaflet-shaped aluminum pigment paste were provided and covered with xylene (100 g). The preparation was left in a closed vessel for 24 hours and homogenized for 2 hours with a slow speed stirrer. The preparation under stirring and atmosphere of dried nitrogen was provided with tetra-n-butyl orthotitanate (40 g) and homogenized for 1 hour with a slow-speed stirrer and heated under reflux for 12 hours. Then again tetra-n-butyl-orthotitanate (40 g) was added with stirring under dry nitrogen atmosphere after re-cooling to room temperature and was stirred for further 5 hours. Then tetra-n-butyl-orthotitanate (40 g) was again added and stirred homogeneously to obtain a liquid coating agent. Subsequently the coating agent (80 g) was diluted with xylene (75 g) and methyl ethyl ketone (5 g) and were filled in a 400 ml aerosol and loaded with propane-butane propellant mixture (200 g). The contents were then applied to degreased and cleaned steel plates and were dried for 1 day at room temperature (20-25 degrees C) under normal humidity conditions (30-60% humidity) to obtain an abrasion-resistant gray metallic coating with good and active corrosion protection.
