With strict quality control and mature production technology, our GMA ensures stable curing performance, excellent compatibility, and reliable long-term industrial application. Free samples, complete technical documents, and factory bulk supply are available for global clients.

Key Features & Performance Advantages of GMA

Glycidyl Methacrylate (GMA) stands out from ordinary acrylic monomers due to its unique molecular structure and excellent modification capability.

• Dual reactive functional groups enable both UV curing and epoxy cross-linking, greatly improving coating hardness, adhesion, solvent resistance, and aging resistance.

• Ultra-high purity grade with low moisture and low APHA color effectively avoids yellowing, incomplete curing, and formula instability during production.

• Excellent compatibility with acrylic resins, polyester, polyolefin, PLA, PBAT, and most organic solvents, suitable for diverse industrial formulations.

• Powerful modification effect enhances weather resistance, mechanical strength, abrasion resistance, and waterproof performance of polymer materials.

• Stable physical and chemical properties ensure consistent quality in mass production, reducing product defect rates for downstream manufacturers.

Industrial Applications

1. UV Curable Coatings & Powder Coatings

GMA is an essential functional monomer for UV-curable coatings and powder coatings. It effectively improves surface hardness, adhesion, corrosion resistance, and weather resistance, solving common coating problems such as peeling, poor gloss, and weak durability. Widely applied in metal surface coating, automotive parts, furniture paint, and industrial equipment finishing.

2. PCB Solder Resist Ink & Industrial Printing Ink

High-purity GMA improves curing speed, insulation performance, and solvent resistance of electronic ink. It meets high-precision circuit board manufacturing standards and ensures stable electrical performance in long-term service.

3. PLA & PBAT Biodegradable Plastic Modification

GMA acts as an efficient chain extender and compatibilizer for biodegradable polymers. It increases molecular weight, enhances material toughness, improves processing fluidity, and solves brittleness and poor wear resistance of eco-friendly plastics. It is widely used to upgrade biodegradable film, packaging materials, and injection-molded products.

4. Adhesives & Sealants

By introducing active epoxy groups, GMA significantly strengthens bonding strength, water resistance, and aging resistance of acrylic adhesives and sealants, ideal for industrial bonding and waterproof sealing applications.

5. Functional Resin Synthesis

GMA can be copolymerized with various monomers to produce high-performance acrylic resins, ion-exchange resins, and antistatic resins for chemical, electronic, and new energy industries.
