Abstract
An apparatus for depositing a coating composition onto a substrate, said apparatus comprising: a) a spray device comprising a coating composition reservoir, a pump, a spray nozzle and a coating composition conduit configured to connect the coating composition reservoir to the spray nozzle; b) a vapor generator; and c) electromechanical means for automatically moving the spray nozzle relative to the substrate; characterized in that the vapor generator is configured to directly spray vapor onto the spray nozzle and comprises: i) a fluid reservoir capable of containing a fluid to be vaporized; ii) a vaporizer configured to convert the fluid into vapor; and iii) a vapor conduit configured to deliver a stream of vapor from the vaporizer through a vapor conduit orifice directly onto the spray nozzle; the invention also relates to a method for depositing a coating composition onto a substrate and to a coated substrate.
