Key Applications of Methacrylic Acid (MAA)
1. Methacrylate Monomer Synthesis: Used to produce methacrylates such as MMA, EMA, and BMA; a core upstream raw material for PMMA (acrylic glass).
2. Water-based Coatings and Emulsion Polymerization: Acts as a comonomer to introduce carboxyl groups, enhancing paint film adhesion, pigment dispersion, and water resistance; used in architectural coatings and industrial anti-corrosion coatings.
3. Adhesives Industry: Used as a modifying monomer for acrylic emulsion adhesives, pressure-sensitive adhesives, and sealants to improve bonding strength and substrate wetting capabilities.
4. Functional resins: Cation exchange resins, superabsorbent polymers (SAP), and raw materials for photoresists/photosensitive resins.
5. Other applications: Textile and leather treatment agents, concrete admixtures, oilfield chemicals, and rubber modification.
Storage, Transport, and Safety Instructions
Methacrylic acid is classified under UN2531 (Class 8 Corrosive Substance). It requires compliant packaging for hazardous chemicals; standard packaging is 200kg steel drums, though ISO tank containers are also available. Wear acid-resistant goggles, protective clothing, and a respirator during handling; avoid direct contact with skin and eyes. Please refer to the MSDS for detailed safety handling procedures.

FAQ
Q1: What is the typical MAA content?
A: Mainstream industrial-grade MAA has a purity of ≥98.5%.
Q2: What is the difference between Methacrylic Acid (MAA) and Acrylic Acid (AA)?
A: MAA molecules contain an additional methyl group; resulting polymers exhibit higher glass transition temperatures (Tg) and superior hydrolysis resistance, making them ideal for weather-resistant coatings and high-adhesion resins. Acrylic Acid (AA) is primarily used for superabsorbent polymers and standard water-based emulsions.
Q3: What is the UN number for transporting Methacrylic Acid?
A: UN2531; Hazard Class 8 (Corrosive Substance), with a subsidiary risk of Flammable Liquid.
Q4: What are the packaging options?
A: Standard 200kg steel drums; bulk orders can be shipped via ISO tank containers.
