Abstract (en)
[origin: WO2021148078A1] The invention relates to a method for applying a thin coating to an inner surface (10) of a through-opening (9), in particular a through-opening (9) of a finned-tube heat exchanger (12), and/or a through-hole, wherein a coating agent (2) is introduced into a stream of compressed air (1), and thereby broken down into very fine droplets, and a nozzle jet (3) generated by a convergent-divergent jet nozzle with a constriction (5) is subsequently used to apply this coating agent at a high flow velocity to the surface (10) to be coated.
