Description

Ethyl Triglycol Methacrylate is a specialized methacrylate ester monomer featuring a hydrophilic triethylene glycol spacer. This compound is valued for its ability to impart flexibility, hydrophilicity, and reactive sites into polymer chains, enabling the creation of advanced materials with tailored properties. It is essential for formulators and polymer chemists in industries such as advanced coatings, adhesives, and specialty polymers where performance customization is critical.

Application

• Hydrophilic Coatings: A key monomer for producing water-borne, flexible, and durable coatings for textiles, paper, and industrial surfaces.
• Adhesive & Sealant Formulations: Used to enhance adhesion, flexibility, and moisture resistance in pressure-sensitive adhesives and construction sealants.
• UV-Curable Resins & Inks: Serves as a reactive diluent and crosslinker in UV-curable systems for printing inks, 3D printing resins, and overprint varnishes.
• Biomedical & Hydrogel Polymers: Employed in the synthesis of hydrogels for contact lenses, wound dressings, and drug delivery systems due to its biocompatibility and water-absorbing capacity.
• Modifier for Acrylic Resins: Incorporated to improve the toughness, weatherability, and low-temperature performance of acrylic plastics and elastomers.
• Fiber Optic Coatings: Used in coatings for optical fibers to provide protective, flexible, and transparent layers.

Quality Control

Our Ethyl Triglycol Methacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile determination, to ensure it meets precise customer specifications and industry benchmarks. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C under an inert atmosphere (e.g., nitrogen) to prevent oxidation and polymerization. Keep away from heat, sparks, and incompatible materials such as strong oxidizing agents and initiators.
