Description

Glycidyl Methacrylate (GMA) is a high-purity, versatile monomer featuring both a reactive methacrylate group and an epoxy group. This bifunctionality makes it a critical building block for synthesizing advanced polymers with tailored properties for demanding industrial applications. It is essential for manufacturers in the coatings, adhesives, and specialty plastics sectors seeking to enhance product performance, durability, and adhesion.

Application

• Crosslinking Agent for Coatings & Resins: Imparts excellent hardness, chemical resistance, and weatherability to acrylic, polyester, and epoxy-based coatings for automotive, industrial, and marine applications.
• Adhesive & Sealant Formulations: Enhances adhesion to diverse substrates and improves cohesive strength in structural adhesives, pressure-sensitive adhesives (PSAs), and sealants.
• Fiber Reinforced Plastics (FRP): Used as a reactive diluent and modifier in vinyl ester and unsaturated polyester resins for composites in construction, transportation, and chemical tanks.
• Photopolymer & UV-Curable Systems: A key component in inks, varnishes, and 3D printing resins due to its fast curing under UV light.
• Biomaterial & Hydrogel Synthesis: Serves as a functional monomer for creating crosslinked polymer networks used in contact lenses, drug delivery systems, and medical devices.
• Surface Modifier & Grafting Agent: Used to functionalize surfaces of fibers, fillers, and nanoparticles to improve compatibility with polymer matrices.
• Ion Exchange & Chelating Resins: A precursor for resins used in water treatment, metal recovery, and catalysis.
• Impact Modifiers & Toughening Agents: Incorporated into engineering plastics to improve impact strength and fracture toughness.

Quality Control

Our Glycidyl Methacrylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, epoxy value, and acid value. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its reactive epoxy group and sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize polymerization. Isolate from strong acids, bases, and oxidizing agents.
