Description

3,6,9,12-Tetraoxatridec-1-Yl Methacrylate is a specialized methacrylate monomer featuring a hydrophilic tetraethylene glycol spacer unit. This compound is valued for its unique ability to impart water solubility, flexibility, and biocompatibility to polymer chains. It is primarily sought by formulators and researchers in the coatings, adhesives, biomedical materials, and personal care industries for developing advanced functional polymers.

Application

• Hydrophilic Coatings: A key monomer for creating water-soluble, non-fouling, or low-friction surface coatings on medical devices and membranes.
• UV/EB Curable Systems: Used in formulations for inks, adhesives, and coatings that cure rapidly under ultraviolet light or electron beams, offering enhanced flexibility.
• Biomedical Hydrogels: Serves as a crosslinkable building block for synthesizing hydrogels used in drug delivery systems, wound dressings, and tissue engineering scaffolds.
• Adhesives & Sealants: Imparts improved adhesion to moist surfaces and internal flexibility in pressure-sensitive and structural adhesive formulations.
• Personal Care Polymers: Employed in the synthesis of film-forming agents, thickeners, and emulsifiers for cosmetics and hair care products.
• Chemical Modification: Used to graft hydrophilic poly(ethylene glycol) (PEG) chains onto various polymers or surfaces to enhance biocompatibility and reduce protein adsorption.
