We do not sell one coating and call it universal. Each grade is formulated against a named active or a named problem, and supplied ready to disperse in water or solvent.

MNaq series, metallic gold
The problem
Most coating trouble starts before the pan: blends weighed out by hand, parameters guessed on the first batch, and a shade that drifts from one order to the next.
Blending on site
Every polymer, plasticiser and pigment weighed out by hand is a place for batch to batch variation to enter a validated process.
The first batch is a trial
Suppliers in this category do not publish coater settings, so the first run on your equipment becomes the experiment.
A shade that drifts
A repeat order matched by eye rather than against the tablet you approved comes back as a fresh interpretation of it.
How we fix it
Ready-mix
A ready-mix arrives as a single dry blend. Nothing is weighed or blended at your end, which removes the step where variation usually enters.

No supplier in this category publishes coater settings. We do, per pan size, because the first batch on your equipment should not be an experiment.

Shade is matched against your reference tablet and confirmed before release, so a repeat order reproduces the finish you approved.

Industry
Pharmaceutical
Solid dosage manufacturers working under the Drugs and Cosmetics Act in India, and export oriented units supplying regulated markets abroad, who need enteric, moisture barrier, sustained release or standard film coating materials for tablets and capsules.
Nutraceutical
Manufacturers regulated under FSSAI producing health supplements, multivitamins, iron tablets and functional tablets that require film coating, taste masking or moisture protection.
Ayurvedic and herbal
ASU manufacturers working under Schedule T whose dark, mottled or hygroscopic herbal cores require extra white film coats, pigmented seal coats or hygroscopic adsorbents.
Formulation development
Development teams and R&D units looking for active specific coating grades with documented application parameters and dissolution profiling support.
Contract manufacturing
Contract and toll manufacturers running coating pans or auto coaters who need a reliable, consistent ready-mix supply with batch to batch shade reproducibility.
Compliance
Our plant at Tahliwal runs a quality control laboratory, a segregated sampling area and a quarantined reject store. Those rooms are what a WHO-GMP claim actually describes, and they are photographed rather than asserted.

Reading
Insight
Why an enteric coat runs cooler than a film coat
The two bands in our parameter tables are not a preference. They come from what the polymer does at temperature, and running the wrong one costs gastro resistance.
Guide
Coating defects and what causes them
Logo bridging, picking, orange peel and the failures that only show on stability.

FAQ
Something went wrong on the pan
Pick the defect off the batch in front of you. Every cause listed here is one we have chased down on a real pan, and the grade beside it is what we changed to.
What you are seeing
The film lifts out of an embossed logo or break line and spans across it, so the debossing goes shallow or disappears.
Usual causes
What we would change
An extra white grade reaches full cover at a lower build-up, so there is less film sitting over the logo by the time the core is hidden.
Grades that address it

Share the core composition, the shade reference and the coater you run. We formulate a grade and supply a trial quantity with the application parameters.
