This article describes a novel nozzle attachment for coating guns which are used to deposit magnetic compounds on substrates for producing magnetic disks. This nozzle attachment has the advantage that the stem of the gun is constantly surrounded by the agitated coating medium, so that there is no dead volume within the gun or a clumping of the coating medium. In conventional guns used for spraying, nebulizing or coating, the exit nozzle is screwed to the front of the stem of the coating gun, which inevitably leads to a dead volume. In addition, particularly with heavily sedimenting liquid mixtures, there is an increased risk of clumping, since in the area of the dead volume, the coating medium is at a standstill.
