Preparation principle
Following the Mayer Rod film coating principle, for higher viscosity fluids, the gap film coating rod reduces clogging and eliminates scratches. By winding smaller wires at pitches (see photo), the cavity created is wide and shallow, allowing thick coatings to flow better. Smaller wires create smaller interruptions in the coating flow, allowing for more complete wetting of the coating.
