Abstract
A coating process for coating a surface of a glass substrate in normal air pressure, in which coating process at least one liquid starting material is atomized into droplets and the formed droplets are guided towards the surface to be coated. The formed droplets are vaporized substantially close to the surface to be coated before the droplets contact the surface to be coated by bringing to the coating process the thermal energy needed for vaporizing the droplets with the glass substrate.

Coating process for coating surface of a glass substrate in normal air pressure, comprising:
- at least one liquid starting material is atomized into droplets and the formed droplets are guided towards the surface to be coated such that the starting materials react on the substrate surface, wherein the formed droplets are vaporized substantially close to the surface to be coated before the starting materials react on the substrate surface by bringing to the coating process the thermal energy needed for vaporizing the droplets with the glass substrate.
Coating apparatus for providing a coating on a surface of a glass substrate in normal air pressure, which coating apparatus comprises a deposition chamber provided with at least one atomizer for atomizing into droplets at least one liquid starting material used for coating the glass substrate and for directing the droplets towards the surface to be coated of the glass substrate such that the starting materials react on the substrate surface, wherein the coating apparatus is arranged to vaporize the droplets directed towards the surface to be coated of the glass substrate substantially close to the surface to be coated before the droplets react on the surface to be coated of the glass substrate.
Process for providing thermal energy to a surface to be coated, comprising:
- employing a hot glass substrate in a coating process for supplying the amount of thermal energy to the coating process needed for vaporizing droplets substantially close to the surface to be coated such that the starting materials react on the substrate surface, the droplets being formed from at least one liquid starting material and directed towards the surface to be coated of the glass substrate.
