High Purity Methacrylic Acid

Methacrylic Acid is a versatile functional monomer with ≥99.5% purity, featuring a reactive double bond and carboxyl group. It serves as the core raw material for PMMA (acrylic glass), coatings, adhesives, and synthetic resins. Our MAA offers excellent thermal stability, low color, and consistent polymerization performance, ensuring high-quality results in both solution and emulsion processes.

FAQ

Q: What is the difference between Methacrylic Acid and Acrylic Acid?

A: MAA has a methyl group (CH₃) that provides better hydrophobicity, flexibility, and impact resistance in polymers. Acrylic Acid offers faster polymerization and harder films. Choose MAA when you need improved weatherability and toughness.

Q: What happens if MAA solidifies during shipping? How to handle it?

A: MAA freezes at 15°C. To reliquefy, warm the container to 30-40°C using hot water circulation or heated blankets. Never use open flames or local overheating to avoid explosion risk. Stir well before sampling.
