Atocoat™ (Atoll Coat) series comprise of Methacrylic acid copolymers type A, B & C, conforming to USP/NF & EP specifications. It is used in film coating, enteric coating, sustained release, moisture barrier, taste masking, colon target, binders, matrix forming, and transdermal-therapeutic systems, across all oral solid dosage forms including multi-particulates, regular or matrix tablets, patches, and hard or soft-gel capsules.
Protects active ingredients from moisture and delays drug release until the target site in the GI tract.
Controls the rate of drug release over an extended period for consistent therapeutic effect.
Creates a barrier around bitter active ingredients, improving palatability and patient compliance.
Supports transdermal patch matrix systems, tablet binding, and encapsulation applications.
Each grade is differentiated by its copolymer type and functionality. Talk to our technical team to find the right fit for your formulation.

One of the major challenges in pharmaceutical formulations is masking the unpleasant taste of certain drugs. Atocoat, as a taste masking polymer, ensures that the medication is palatable without compromising its efficacy.
Atocoat acts as a reliable sustained release polymer, allowing the active ingredient to be released gradually over a specified period, reducing the frequency of dosage and enhancing patient convenience.
The Methacrylic acid copolymer used in Atocoat protects the active ingredients from environmental factors like moisture, light, and air, improving the shelf life of the finished product.
Atocoat is compatible with a wide range of active pharmaceutical ingredients and excipients, making it a versatile choice for fast-release or extended-release formulations alike.
Atocoat is user-friendly and can be applied using standard coating equipment, making it a cost-effective solution for manufacturers, with consistent performance and smooth coatings free of cracking or peeling.
As a leading Methacrylic Acid Copolymer manufacturer, Atoll is committed to delivering superior quality and innovative coating solutions. Our state-of-the-art manufacturing processes ensure that our polymers meet rigorous USP/NF & EP standards. With years of experience and expertise, we are dedicated to providing products that enhance the efficacy and safety of your formulations.
pH-dependent grades that dissolve at a specific target point in the GI tract, protecting sensitive APIs.
pH-independent Ammonio Methacrylate copolymers for controlled, extended drug release.
Ready-to-use 30% aqueous dispersion grades for efficient, solvent-free film coating.
Atocoat range is a high molecular weight polymer, it cannot be absorbed by body. Thus, it is safe for human consumption.
Test for toxicological tolerance shows that it does not have any pronounced or physiological action.
Powder: Store at a dry place, below 45°C.
Liquid: Store at a dry place, between 5°C to 35°C. Do not freeze.
