Description

2-(Methacryloyloxy)Ethyl Phosphate is a reactive organophosphate monomer featuring both a polymerizable methacrylate group and a phosphate ester functionality. This unique dual reactivity makes it a critical intermediate for imparting adhesion, hydrophilicity, and flame-retardant properties to polymeric materials. It is essential for formulators and polymer chemists in industries requiring advanced surface modification and material performance enhancement.

Application

• Dental & Biomedical Adhesives: A key component in self-etching dental primers and bonding agents, promoting adhesion to tooth dentin and enamel.
• Metal Surface Treatment & Coatings: Used as an adhesion promoter in primers and anti-corrosion coatings for metals like steel and aluminum.
• Flame Retardant Monomer: Incorporated into acrylic resins, polyurethanes, and other polymers to enhance flame retardancy.
• Hydrophilic & Biocompatible Polymers: Serves as a co-monomer for producing hydrogels, contact lens materials, and other biocompatible polymers requiring moisture retention.
• Fiber & Textile Treatment: Applied to modify synthetic fibers for improved dyeability, antistatic properties, and soil release.
• Paper & Packaging Coatings: Enhances the wet strength, printability, and barrier properties of paper and paperboard.
• Composite Materials: Improves the interfacial adhesion between inorganic fillers (e.g., glass, minerals) and organic polymer matrices.
• Electronics & Optical Materials: Used in photoresists, optical adhesives, and encapsulants due to its reactive nature and ability to modify surface energy.
