Ready-mix coating systems for pharmaceutical manufacturing.
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.
We make the coating material, not the coating machine. If you run a pan, we make what goes in it.

What we make
Coating systems developed around your formulation.
Rglax Pharma manufactures ready-mix tablet coating material, polymers and resins at Tahliwal, in Una district of Himachal Pradesh. The range runs under the Rglax Coat brand and covers 10 system families across 22 coded grades.
A ready-mix arrives as a single dry blend. You disperse it in water or solvent and spray it. Nothing is weighed or blended at your end, which removes the step where batch to batch variation usually enters a validated process.
Shade is matched against a reference tablet you send us and confirmed before release, so a repeat order reproduces the finish you approved rather than a fresh interpretation of it.
Product specification
Every grade is published with the parameters it runs on.
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.

The works
Every batch is tested before it leaves.
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.

Who we supply
Drugs and Cosmetics Act
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.
FSSAI
Nutraceutical
Manufacturers regulated under FSSAI producing health supplements, multivitamins, iron tablets and functional tablets that require film coating, taste masking or moisture protection.
Schedule T
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.
R&D and FDD teams
Formulation development
Development teams and R&D units looking for active specific coating grades with documented application parameters and dissolution profiling support.
Toll and third party
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.
What you get
Ready-mix, no in-house blending
Disperse in water or solvent and spray straight into the coating pan. Nothing is weighed or blended at your end, which removes the step where batch to batch variation usually enters.
Active specific grades
Coating grades developed against named pharmaceutical actives, including Pantoprazole, Amoxycillin with Clavulanate, Azithromycin and Sodium Valproate, rather than one film sold for everything.
Shade matching against your sample
Every batch is colour matched against your reference tablet before release, so a repeat order reproduces the finish you approved rather than a fresh interpretation of it.
Trial quantities with the parameters
Trial material ships with the application parameters for your pan size, so the first coating run is guided rather than experimental.
Support through scale-up
Technical support through trials, scale-up and dissolution profiling, for conventional pans and auto coaters alike.
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.

Coating defects and what causes them
Logo bridging, picking, orange peel and the failures that only show on stability.

Common questions
Something went wrong on the pan
Tell us what you are seeing.
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
- 01Film applied beyond the build-up the debossing can carry
- 02A film with high internal stress as it dries
- 03Shallow or steeply cut debossing on the punch
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.
