Description

2-Isocyanatoethyl Methacrylate is a bifunctional monomer that combines a reactive methacrylate group with an isocyanate group in a single molecule. This unique structure makes it a critical cross-linking agent and adhesion promoter in advanced polymer systems. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance material durability, chemical resistance, and bonding performance.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and cross-linker to improve hardness, scratch resistance, and adhesion to various substrates.
• Adhesives & Sealants: Used as an adhesion promoter and to introduce urethane linkages, enhancing bond strength and flexibility.
• Dental & Biomedical Polymers: A key monomer in the formulation of durable, biocompatible resins for dental composites and bone cements.
• Fiber Optic Coatings: Imparts excellent mechanical properties and environmental stability to protective coatings for optical fibers.
• Automotive & Industrial Coatings: Enhances the weatherability, chemical resistance, and gloss retention of high-performance finishes.
• Modification of Polymers: Used to graft functional isocyanate groups onto polymer backbones (e.g., polyols, acrylics) for further chemical modification.

Quality Control

Our 2-Isocyanatoethyl Methacrylate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing assay, isocyanate content, and critical impurities is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize polymerization and maintain stability. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and moisture.
