Construction Chemistry
Methyl Methacrylate (MMA)
Formula:
C₅H₈O₂
GOST/CAS:
ГОСТ 20370-74 / 80-62-6
Methyl methacrylate (MMA) is a colorless, transparent, volatile liquid with a characteristic sharp, fruity odor. It is a crucial monomer in the chemical industry, serving as the base raw material for the synthesis of a wide range of acrylic polymers and copolymers. Thanks to its unique chemical properties, MMA is an indispensable component in the production of organic glass (acrylic), paints and coatings, adhesives, and engineering plastics used in construction, automotive, medicine, and outdoor advertising.
Applications
PMMA (Acrylic Glass) Production: The primary raw material for producing polymethyl methacrylate (PMMA) — a strong, lightweight, and optically transparent material widely used in glazing, advertising structures, sanitary ware, and lighting fixtures.
Paints and Coatings: Used in the synthesis of acrylic dispersions and resins for producing high-quality facade and interior paints, automotive enamels, road marking paints, and weather-resistant protective coatings.
Adhesives and Sealants: A key component in the production of fast-curing two-component structural acrylic adhesives, construction sealants, as well as dental and bone cements in medicine.
Plastic Modifiers: Used as a comonomer (e.g., MBS modifiers) to improve impact resistance, transparency, and processing characteristics of polyvinyl chloride (PVC) and other polymers.
Key Advantages
Unique Optical Properties of Polymers: MMA-based materials (particularly acrylic glass) feature exceptionally high light transmission (up to 92%) and absolute transparency, surpassing ordinary silicate glass.
High Weather and UV Resistance: Provides end products with exceptional durability, resistance to yellowing, and retention of physical and mechanical properties even under prolonged exposure to sunlight and precipitation.
Excellent Reactivity: Ensures fast and predictable homopolymerization and copolymerization reactions with a wide range of other monomers (styrene, butyl acrylate), allowing the creation of materials with precisely tailored properties.
Quality Stability: A high-purity product, strictly stabilized with a special inhibitor (usually Hydroquinone or MEHQ), which reliably prevents spontaneous polymerization under proper storage and transportation conditions.
Storage & Transportation
- Store in a cool, dry, well-ventilated area at a temperature not exceeding 25°C (preferably in a darkened place).
- Keep away from direct sunlight, heat sources, sparks, static electricity, and open flames (the product is a highly flammable liquid).
- Avoid contact with strong oxidizers, reducing agents, acids, alkalis, and peroxides.
- It is necessary to regularly monitor the inhibitor concentration and the presence of dissolved oxygen (which is required for inhibitor activation). Do not store the product under an inert gas atmosphere.
