Methacrylic acid (MAA) is also known as methacrylic acid or 2-methyl-2-acrylic acid. CAS No. 79-41-4. It is a colorless transparent liquid at room temperature. Melting point 14°C. Boiling point 159-163°C (100KPa), flash point 77°C. Soluble in hot water, ethanol and most organic solvents. Easy to polymerize. It can form an explosive mixture with air, and the explosion limit is 2.1% to 12.5%.
What is the chemical MAA used for?
1. Core Applications in Polymer Synthesis
MAA is a key monomer for polymer synthesis:
Homopolymerization: Makes poly(methyl methacrylate) (PMMA), which has good film-forming and weather resistance, used in coatings and adhesives.
Copolymerization: Mixes with monomers like methyl methacrylate or ethyl acrylate to make copolymers.
2. Use as Raw Material for Coatings and Adhesives
Coatings industry: Methacrylic acid MAA is key for acrylic coatings. The acrylic resin made from it (as a monomer) is a film-forming substance, giving coatings good adhesion, water resistance, and chemical corrosion resistance. Used in building, automotive, and industrial anti-corrosion coatings.
Adhesives field: MAA helps make acrylic ester adhesives. Adjusting its content boosts adhesive strength and weather resistance. Suitable for bonding metals, plastics, wood, used in packaging, construction, electronics.
3. Applications in Pharmaceutical and Daily Chemical Industries
Pharmaceutical field: MAA CAS 79-41-4 is an intermediate for some drug synthesis; its derivatives are drug excipients (e.g., skeleton materials for sustained-release formulations) to control drug release.
Daily chemical industry: Methacrylic Acid polymers are used in cosmetics (thickeners, film-forming agents) for skincare products and hair gel. They improve product texture, usability, and stability.
4. Applications in Other Industrial Fields
Textile industry: MAA copolymers act as textile auxiliaries (sizing, finishing), enhancing fabric stiffness, wear resistance, and color fastness.
Water treatment: MAA polymers are flocculants for industrial/domestic sewage, removing suspended particles and organic impurities.
Oilfield: MAA makes drilling fluid additives to improve drilling fluid performance, ensuring smooth drilling.
