Description

1-(Methacryloyloxy)Ethylphosphonic Acid is a high-purity, functional monomer featuring both a polymerizable methacrylate group and a phosphonic acid moiety. This dual functionality makes it a critical component for introducing permanent, hydrophilic, and metal-chelating properties into polymer matrices. It is essential for manufacturers in advanced material sectors requiring precise surface modification and enhanced adhesion to metal or mineral substrates.

Application

• Dental & Biomedical Adhesives: As a key monomer in self-etching dental primers and cements to promote adhesion to tooth dentin and enamel.
• Scale Inhibitors & Water Treatment Polymers: Incorporated into copolymers for industrial water systems to prevent calcium carbonate and sulfate scale formation.
• Metal Surface Treatment & Corrosion Protection: Used in formulations for metal pre-treatment coatings, enhancing paint adhesion and providing corrosion resistance.
• Hydrogel & Contact Lens Materials: Imparts permanent hydrophilicity and biocompatibility in silicone hydrogel formulations for medical devices.
• Ion-Exchange & Chelating Resins: Serves as a functional monomer for creating resins that selectively bind heavy metal ions from solutions.
• Adhesive Promoters for Composites: Improves the interfacial bond between inorganic fillers (e.g., glass, minerals) and organic polymer resins in composite materials.
