Description

Triethylene Glycol Dimethacrylate is a high-purity, difunctional methacrylate monomer characterized by its two reactive double bonds. This chemical is essential for creating highly cross-linked polymer networks, offering superior hardness, chemical resistance, and durability in the final cured material. It is a critical raw material for manufacturers in the coatings, adhesives, dental composites, and optical lens industries seeking to enhance product performance.

Application

• Cross-linking Agent for Coatings & Inks: Imparts excellent scratch resistance, hardness, and solvent resistance to UV-curable and thermally cured industrial coatings, overprint varnishes, and printing inks.
• Dental Restorative Composites: Serves as a key monomer in dental filling materials and restorative resins, providing high strength, low shrinkage, and biocompatibility upon polymerization.
• Adhesive & Sealant Formulations: Used to formulate high-performance anaerobic, acrylic, and structural adhesives that require fast curing and strong, durable bonds.
• Optical Lens Production: A vital component in the manufacture of hard, transparent plastic lenses for eyeglasses and optical instruments due to its clarity and rigidity.
• Fiber Optic Coatings: Applied as a primary coating to protect optical fibers, offering excellent mechanical protection and environmental stability.
• Acrylic Sheet & Casting Resins: Enhances the heat resistance and surface hardness of cast acrylic sheets, signage, and industrial components.
• 3D Printing Resins (SLA/DLP): Functions as a reactive diluent and cross-linker in photopolymer resins for stereolithography, improving resolution and mechanical properties of printed parts.
• Rubber & Elastomer Modification: Used to modify the properties of synthetic rubbers, improving cross-link density and resistance to heat and oils.

Quality Control

Our Triethylene Glycol Dimethacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, color, and inhibitor content. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to guarantee consistency and support your quality assurance protocols.

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). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially filled containers to prevent premature polymerization and maintain stability. Keep away from heat, sparks, and open flame.
