Metallic and pearl film coat

The MNaq series is a non-aqueous ready-mix film coat that gives a metallic or pearl effect finish. Each shade carries its own code, and every code runs the same way on the coater. The shade is matched and confirmed against your reference sample before the batch is released, so a repeat order reproduces the finish you approved rather than a fresh interpretation of it.

A metallic or pearl effect comes from pigment lying flat on the tablet surface, so the finish depends as much on the surface underneath as on the coat itself. A smooth core, or a seal coat below the metallic layer, gives the pigment something even to lie on. Run the lower non-aqueous band with a steady spray rather than a fast one. Confirm shade against your reference sample under the light you actually inspect under, because metallic pigments read differently in daylight and under tube light. Every code in the series runs on the same parameters, so a shade change does not mean a process change.
