GLYCIDYL METHACRYLATE 2,3-Epoxypropyl methacrylate

Basic Information

Product Name: Glycidyl Methacrylate (GMA);CAS No.: 106-91-2Molecular Formula: C₇H₁₀O₃;Molecular Weight: 142.15 g/mol Appearance: Colorless to pale yellow transparent liquid;Boiling Point: 189°C (372°F);Flash Point: 76°C (169°F);Solubility: Miscible with most organic solvents, slightly soluble in water

Key Properties

• Reactive Functional Groups: Contains both an epoxy group and a methacrylate group, enabling dual reactivity for cross-linking and grafting reactions

• Chemical Stability: Stable under normal storage conditions, but polymerizes easily when heated or exposed to initiators

• Viscosity: ~4 mPa·s at 25°C, ensuring good processability in coating and adhesive applications

• Hydrophobicity: Low water absorption rate, providing excellent moisture resistance in finished products

Industrial Applications

• Coatings & Paints: Acts as a cross-linking agent to improve scratch resistance, chemical resistance, and adhesion properties of automotive, industrial, and aerospace coatings

• Adhesives & Sealants: Enhances bonding strength and durability in structural adhesives, especially for metal-plastic composites

• Polymer Modification: Grafts onto polyolefins, polyesters, and rubber to introduce epoxy functionality, improving compatibility and mechanical performance

• Textile Industry: Used in textile finishing agents to impart wrinkle resistance and dimensional stability to fabrics

• Electronic Materials: Serves as a key component in photoresists and encapsulants for semiconductor manufacturing

Safety & Handling

• Hazard Classification: Irritating to eyes, skin, and respiratory system; may cause allergic reactions

• Storage Requirements: Store in a cool, dry, well-ventilated area away from heat sources and oxidizing agents

• Transport Regulations: Classified as a hazardous material under UN 2810 (Toxic liquid, organic, n.o.s.) for international shipping

• Personal Protection: Wear chemical goggles, gloves, and respiratory protection when handling
