Description

Poly(Glycidyl Methacrylate) (PGMA) is a versatile and highly functional epoxy-containing polymer. Its core value lies in its pendant glycidyl groups, which are highly reactive epoxides, enabling facile cross-linking and covalent bonding with a wide range of nucleophiles. This makes it an essential precursor and additive for advanced material synthesis across industries such as coatings, adhesives, chromatography, and biomedical engineering, where surface modification and controlled functionalization are critical.

Application

• Chromatography Media: As a key substrate for manufacturing high-performance affinity, ion-exchange, and size-exclusion chromatography resins due to its excellent chemical stability and ease of ligand immobilization.
• Surface Coatings & Adhesives: Serving as a cross-linking agent and reactive diluent in epoxy-based coating formulations to enhance adhesion, chemical resistance, and durability.
• Biomedical Materials: Functionalization of surfaces for biosensors, tissue engineering scaffolds, and drug delivery systems by providing reactive sites for biomolecule conjugation (e.g., proteins, peptides).
• Composite Materials: Acting as a coupling agent or matrix modifier in fiber-reinforced composites to improve interfacial adhesion between the polymer matrix and inorganic fillers.
• Microsphere Synthesis: Used in the production of uniform polymeric microspheres via dispersion or emulsion polymerization for applications in diagnostics, catalysis, and standard calibration.
• Lithographic Resists: Employed in the formulation of photoresists for microelectronics and printed circuit board (PCB) manufacturing, leveraging its radiation sensitivity and developability.

Quality Control

Our Poly(Glycidyl Methacrylate) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent properties such as epoxy equivalent weight (EEW), molecular weight distribution, residual monomer content, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing these specifications are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). The product is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent hydrolysis of the epoxy groups. Keep away from strong acids, bases, and oxidizing agents.
