Methacrylic Acid (MAA) | Premium Specialty Monomer | CAS 79-41-4
Overview
Methacrylic Acid (MAA), also known as Glacial Methacrylic Acid, is a clear, colorless liquid with an acrid odor. The critical presence of a methyl group in its molecular structure provides immense steric hindrance, transferring exceptional hardness, extreme weatherability (UV resistance), and optical clarity to its downstream polymers. It is the uncompromising foundational monomer for manufacturing high-end automotive coatings, specialty structural adhesives, and ion-exchange resins.
Product Description
Methacrylic Acid (MAA) is a clear, highly reactive unsaturated carboxylic acid. The critical presence of a methyl group in its molecular structure provides immense steric hindrance, transferring exceptional hardness, extreme weatherability (UV resistance), and optical clarity to its downstream polymers. It is the uncompromising foundational monomer for manufacturing high-end automotive coatings, specialty structural adhesives, and ion-exchange resins.
At Shandong Yinglang Chemical Co., Ltd., established in 2011, we supply massive volumes of Premium Methacrylic Acid to multinational resin fabricators and specialized coating gigafactories. Operating strictly under Class 8 Dangerous Goods protocols, we ensure our MAA is expertly stabilized with precise MEHQ inhibitor levels and transported under uncompromising temperature-controlled logistics.
For high-performance automotive clears and optically pure resins, exact purity and specific inhibitor distribution are mandatory. Typical specifications:
| Purity (MAA) | ≥ 99.5% |
|---|---|
| Moisture / Water | ≤ 0.2% |
| Inhibitor (MEHQ) | 200 - 250 ppm |
| Color (Pt-Co) | ≤ 15 |
| Freezing Point | ~ 15°C |
- Automotive & Architectural Coatings: Imparts crucial cross-linking sites in thermosetting acrylic resins, providing automotive clear coats with exceptional scratch resistance and non-yellowing UV durability.
- Specialty Adhesives: Formulated into anaerobic adhesives and structural acrylic tapes demanding high shear strength.
- Ion-Exchange Resins: Essential for manufacturing weak acid cation exchange resins used in industrial wastewater purification.
- Textile Finishes: Enhances the adhesion and chemical resistance of premium leather topcoats.
Methacrylic Acid possesses an unusually high freezing point of roughly 15°C. If allowed to freeze during transit, the MEHQ inhibitor physically separates from the acid. Attempting to thaw the product improperly can trigger an immediate, violent polymerization explosion. Yinglang Chemical’s Class 8 DG logistics team actively monitors and maintains all ISO Tank and drum shipments within a strict 18°C–25°C thermal corridor, ensuring your monomer arrives perfectly liquid, uniformly stabilized, and ready for immediate reaction.
Because MAA is highly corrosive and prone to rapid freezing, we utilize heavy-duty packaging for secure ocean transit:
- ISO TANKS (20 MT) (Highly recommended for massive coating resin procurement, fully temperature-monitored).
- 200 KG UN-approved HDPE Plastic Drums.
- 1000 KG IBC Totes.
- Transport Classification: Classified as Class 8 (Corrosive Substance).
- UN Number: UN 2531 | Packing Group: II
- Handling Precautions: EXTREME DANGER. Causes severe skin burns. Readily polymerizes if exposed to heat. Store strictly between 18°C and 25°C to prevent freezing and inhibitor separation. Operators MUST wear full acid-resistant gear.

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
