Description

Glycerol 1,3-Dimethacrylate is a high-purity, bifunctional methacrylate monomer widely used as a reactive crosslinking agent and building block in advanced polymer synthesis. Its dual methacrylate groups enable the formation of dense, three-dimensional polymer networks, imparting enhanced mechanical strength, chemical resistance, and thermal stability to the final materials. This compound is essential for manufacturers in the dental materials, specialty adhesives, optical lens, and advanced coating industries seeking to develop high-performance, durable products.

Application

• Dental Composites & Restorative Materials: A key crosslinker in resin-based composites, crowns, and fillings, providing superior hardness, wear resistance, and low polymerization shrinkage.
• Optical Polymers & Lens Manufacturing: Used in the production of high-refractive-index eyeglass lenses, contact lenses, and intraocular lenses (IOLs) due to its clarity and ability to form stable networks.
• Specialty Adhesives & Sealants: Serves as a core monomer in UV-curable and structural adhesives for electronics, medical devices, and automotive applications, offering fast curing and strong bonds.
• Advanced Coatings & Inks: Imparts scratch resistance, gloss, and weatherability to industrial, automotive, and packaging coatings as well as radiation-curable printing inks.
• Biomedical & Hydrogel Engineering: Employed in the synthesis of hydrogels for drug delivery systems, wound dressings, and tissue engineering scaffolds, allowing controlled crosslink density.
• Lithography & Photoresists: Acts as a photopolymerizable component in photoresists for microelectronics and printed circuit board (PCB) fabrication.

Quality Control

Our Glycerol 1,3-Dimethacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. A Certificate of Analysis (COA) detailing key parameters such as assay, inhibitor content, and impurity profile is provided with every shipment. We support compliance with relevant industry standards, including those for medical and dental applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to maintain purity and prevent premature polymerization. Keep away from heat, sparks, and open flame.
