The invention relates to an aerosol can containing a two-component paint with an aerosol preparation, in particular for use in the automotive industry and for automotive repairs. Said aerosol can contains a binding agent component and a curing component. The binding agent component contains a curable epoxy parent component, solvents and a propellant and the curing component contains a cross-linking agent, which is suitable for curing the epoxy binding agent. The curing component is housed separately from the binding agent component in a cross-linking casing, which is located in the aerosol paint can and can be activated externally.

The invention claimed is: 1. Two-component aerosol paint can with an aerosol preparation, especially for the automotive industry and automotive repair purposes, containing a binding agent component and a curing agent component, characterized in that the binding agent component contains an epoxy parent component capable of being cured, solvent and propellant gas, and the curing agent component contains a cross-linking agent capable of causing the epoxy binding agent to cure, with the curing agent component being accommodated in a cross-linking casing which is located in the aerosol paint can separately from the binding agent component and can be activated externally; and wherein said paint can has an inner casing attached to a cup in the can bottom, a push rod arranged in the inner casing said rod being actuated through the cup and intended to force open the inner casing and acting on a cover arranged at the can-side end of the inner casing and forcing off said cover when actuated. 2. The aerosol paint can according to claim 1, characterized in that a 3:1 through 6:1 ratio by weight exists between the epoxy parent component and the curing agent component. 3. The aerosol paint can according to claim 2, characterized in that the ratio by weight is 4:1 through 5:1. 4. An aerosol paint can according to any one of the above claims, characterized in that the curing agent component contains an aliphatic, cycloaliphatic or aromatic amine, its reaction products and adducts, a polyaminoamide, dicyandiamide, cyclic acid anhydride, a polyisocyanate or amino-functional polyacrylate. 5. An aerosol paint can according to claim 1, characterized in that the epoxy parent component and solvent are present at a ratio by weight of between 75:25 and 50:50. 6. The aerosol paint can according to claim 5, characterized in that the spraying viscosity is between 18' and 30' in a DIN beaker with 3-mm nozzle. 7. Aerosol paint can according claim 1, characterized in that the binding agent component contains ketones, esters, alcohol and/or aromatics as solvent. 8. The aerosol paint can according to claim 7, characterized in that the solvent consists of ketones and esters of a ratio by weight ranging between 50:50 and 90:10. 9. The aerosol paint can according to claim 8, characterized in that the solvent contains acetone and butyl acetate of a ratio by weight ranging between 80:20 and 90:10. 10. An aerosol paint can according to claim 1, characterized in that it contains an epoxy parent component based on glycidyl ethers, glycidyl esters, glycidyl amines, cycloaliphatic epoxys and glycidyl isocyanurates. 11. An aerosol paint can according to claim 1, characterized in that the binding agent component contains 25 to 60% by weight of propellant gas. 12. The aerosol paint can according to claim 11, characterized in that it contains dimethyl ether, propane and/or butane as propellant gas. 13. The aerosol paint can according to claim 12, characterized in that it contains dimethyl ether. 14. The aerosol paint can according to claim 13, characterized in that the binding agent component contains 54% by weight of dimethyl ether. 15. Aerosol paint can according to claim 1, characterized in that the epoxy parent component contains customary additives, in particular pigments, solvents, stabilizers, agents used to influence rheology and/or viscosity and/or emulsifiers. 16. Aerosol paint can according to claim 1, characterized in that it is provided with a low-pressure flat-spray nozzle. 17. Aerosol paint can according to claim 1, characterized by an internal pressure of 4.5 to 6 bar up to 20�� C. 18. Aerosol paint can according to claim 17, characterized by an internal pressure of 5.0 to 6.5 bar up to 20�� C. 19. The aerosol paint can according to claim 1, characterized in that the inner casing consists of metal, preferably aluminum. 20. The aerosol paint can according to claim 1, characterized in that the inner casing has a metal membrane arranged on its bottom end, with the push rod being divided into a trigger pin arranged external to the inner casing and projecting through the can bottom and a push element arranged inside the inner casing. 21. The aerosol paint can according to claim 1, characterized in that the inner casing forms an integral pad or is integrally connected with the cup of the can bottom.
