Description

Ethylene Glycol Methacrylate Phosphate is a specialized functional monomer containing both a polymerizable methacrylate group and a phosphate ester group. This unique bifunctional structure makes it a critical component for imparting adhesion, hydrophilicity, and flame-retardant properties to polymer systems. It is essential for formulators and manufacturers in the coatings, dental materials, and advanced composites industries seeking to enhance material performance at interfaces.

Application

• Dental Adhesive & Restorative Materials: Key monomer for self-etching dental primers and bonding agents, promoting adhesion to dentin and enamel.
• Metal Coatings & Primers: Enhances adhesion of acrylic and other polymer coatings to metal substrates, including steel and aluminum.
• Flame-Retardant Polymers: Acts as a reactive comonomer to introduce phosphorus, improving the flame retardancy of acrylic resins and polyurethanes.
• Hydrophilic Coatings & Hydrogels: Used to create water-absorbent or moisture-retaining surfaces in contact lens materials, biomedical devices, and personal care products.
• Fiberglass Sizing & Composite Coupling Agents: Improves the interfacial bond between glass fibers and polymer matrices in reinforced plastics.
• UV-Curable Inks & Coatings: Serves as an adhesion-promoting functional monomer in formulations requiring rapid curing and strong substrate bonding.
