Description

2-Hydroxyethyl Methacrylate Phosphate is a specialized, high-purity monomer that combines the reactive methacrylate group with a phosphate ester functionality. This unique structure provides excellent adhesion to metal substrates and enhances the hydrophilicity and crosslinking density in polymer systems. It is a critical raw material for formulators in the coatings, dental materials, and advanced adhesive industries seeking to improve product performance and durability.

Application

• Metal Coatings & Primers: As a key adhesion promoter in corrosion-resistant coatings, automotive primers, and coil coatings for aluminum and steel.
• Dental Composites & Cements: Used to formulate self-etching dental adhesives, restorative composites, and cementitious materials due to its bonding capabilities to tooth enamel and dentin.
• UV-Curable Inks & Resins: Serves as a reactive diluent and adhesion enhancer in UV-curable printing inks, overprint varnishes, and 3D printing resins.
• Fiberglass Sizings: Imparts superior bonding between glass fibers and polymer matrices in reinforced plastics (GRP/FRP) and composites.
• Hydrogel & Contact Lens Materials: Provides hydrophilicity and oxygen permeability in the synthesis of soft contact lenses and biomedical hydrogels.
• Industrial & Structural Adhesives: Enhances bond strength on difficult substrates like treated metals and ceramics in anaerobic and acrylic adhesives.
