Description

p-Hydroxyphenyl Methacrylate is a specialized methacrylic ester monomer featuring a reactive phenolic hydroxyl group. This bifunctional structure is critical for synthesizing advanced polymers with tailored properties such as UV curability, adhesion, and biocompatibility. It is an essential raw material for manufacturers in the photoresist, dental materials, optical lens, and specialty adhesive industries seeking to enhance product performance.

Application

• Photoresists & Photopolymers: A key monomer in the formulation of UV-curable resins for electronics, including printed circuit boards (PCBs) and liquid crystal displays (LCDs).
• Dental & Biomedical Materials: Used in the synthesis of biocompatible polymers for dental composites, bone cements, and drug delivery systems.
• Optical Materials: Serves as a co-monomer in the production of high-refractive-index plastics for optical lenses and components.
• Adhesives & Coatings: Imparts excellent adhesion and cross-linking density to industrial adhesives, pressure-sensitive adhesives (PSAs), and protective coatings.
• Surface Modification: Employed to graft functional polymer brushes onto surfaces (e.g., silica, metals) to modify wettability, reduce friction, or introduce specific chemical groups.
• Ion-Exchange Resins: Acts as a precursor for functional resins used in water purification and chromatographic separation processes.
