Rotterdam Chemicals Group supplies high-purity Methacrylic Acid (MAA) used in coatings, adhesives, textiles and plastics. Our MAA is REACH compliant and available in industrial grade. We deliver worldwide from Rotterdam in drums, IBCs and ISO tanks with full documentation and inhibitor options tailored to your formulation requirements.
What is Methacrylic Acid (MAA)?
Methacrylic Acid (CAS 79-41-4) is a clear, corrosive liquid with a sharp, acrid odor. It is a carboxylic acid and monomer used in the manufacture of methacrylate-based polymers and copolymers. MAA imparts hardness, chemical resistance and adhesion in industrial and architectural applications.

Frequently Asked Questions (FAQ)
Is Methacrylic Acid stabilized?
Yes. It is typically supplied with an inhibitor like MEHQ or hydroquinone to prevent unwanted polymerization.
Can MAA be copolymerized?
Yes. It is widely used with MMA, BA, and styrene in a range of copolymer formulations.
What is the main difference between MAA and AA?
MAA provides higher hardness and weather resistance, while AA offers more water solubility and flexibility.
What safety precautions should be taken with MAA?
MAA is corrosive and flammable. It must be handled with PPE and stored in ventilated, inhibitor-stabilized containers.
