FIELD: chemistry.
SUBSTANCE: invention relates to a method of applying a coating on an end surface of a monolithic neutralizer substrate for use in a device for reducing toxicity of emissions. In method of coating end surface of monolithic substrate (10) with liquid (2) containing catalytic component, transporting monolithic substrate to coating roller (1), applying liquid (2) containing catalytic component, on end surface of monolithic substrate (10) due to contact of end surface with coating roller (1), saturated liquid to obtain monolithic substrate (10), having end surface coated with liquid (2). After that monolithic substrate (10) is dried, having end surface covered with liquid (2), and then monolithic substrate (10) is annealed.
EFFECT: technical result of the invention is to automatically and uniformly coat the end surface of the monolithic neutralizer substrate with fluid and accurately control the amount of liquid deposited on the monolithic substrate, thereby avoiding losses.
