Wet-on-wet coating processes are provided to produce multilayer articles. First and second coating materials are sequentially applied on to a structured substrate surface to form a skin layer directly over the structured substrate surface and a bulk layer over the skin layer. The conformability of the skin layer can be adjusted to provide desired surface and bulk properties.

Methods and apparatuses for applying coatings on a baggy web are provided. A Mayer rod and a back-up roll engage with each other to form a nip. The back-up roll has a deformable inner layer with a surface thereof covered by a deformable outer layer. The Mayer rod and the flexible web at a contacting area are impressed into the back-up roll with a machine-direction nip width W and a nip engagement depth D, which enables formation of a coating having a substantially uniform thickness.

A powder deagglomerator includes a vertical flow chamber, a powder inlet tube, and an ultrasonic horn vibrationally coupled to an ultrasonic transducer. The vertical flow chamber includes an outer wall, powder outlet port, and a mounting port sealably engaging an ultrasonic horn. The powder inlet tube extends through the outer wall and is aligned to dispense agglomerated powder in a gaseous stream downward onto a distal end of the ultrasonic horn. A method of using the powder deagglomerator to deagglomerate a powder is also disclosed.
