What this range covers

Metallic and pearl effect coats in the MNaq series give a distinctive brand finish on tablets. Each code is a solvent base ready-mix supplied in the shade agreed against your reference sample.

Metallic gold film coated caplets — Batches finished with the MNaq series. Shade is matched to a reference sample, and metallic pigment reads differently in daylight and under tube light, which is why inspection lighting is fixed before approval.

Metallic blue coated tablets beside an Rglax DB3012 coating dispersion — Batches finished with the MNaq series. Shade is matched to a reference sample, and metallic pigment reads differently in daylight and under tube light, which is why inspection lighting is fixed before approval.

Common questions

Can a custom metallic shade be matched?

Yes. Send a reference sample and the shade is matched and confirmed against it before the batch is released, so a repeat order reproduces the finish you approved.

Does a shade change mean a process change?

No. Every code in the MNaq series runs on the same non-aqueous parameters, so switching shade does not mean requalifying the process.

Why does the finish look uneven on some cores?

A metallic effect depends on pigment lying flat, so the surface underneath matters as much as the coat. A smooth core, or a seal coat below the metallic layer, gives the pigment something even to lie on.
