Description

p-Hydroxyphenyl Acrylate is a high-purity, functional monomer characterized by its phenolic hydroxyl and acrylic ester groups. This bifunctional structure makes it a valuable building block for synthesizing advanced polymers with tailored properties, such as enhanced adhesion, UV reactivity, and chemical resistance. It is primarily sought by R&D and production teams in the photoresist, specialty coatings, and advanced adhesive sectors.

Application

• Photoresist & Photopolymer Formulations: Acts as a key monomer in UV-curable resins for electronics (e.g., printed circuit boards) and stereolithography (3D printing).
• Specialty Coatings & Inks: Imparts improved adhesion to difficult substrates and enhanced weatherability in high-performance industrial and automotive coatings.
• Adhesive & Sealant Chemistry: Used to modify acrylic polymers, increasing polar interactions and bond strength on metals, plastics, and composites.
• Dental & Medical Polymers: Serves as a co-monomer in the synthesis of biocompatible polymers for restorative materials and drug delivery systems.
• Surface Modification Agents: Employed to graft functional polymer brushes onto surfaces for controlled hydrophilicity or specific binding sites.
• Cross-linking Agent: Utilized to introduce photo-reactive or thermally reactive cross-links into polymer networks, improving mechanical and thermal properties.

Quality Control

Our p-Hydroxyphenyl Acrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended. Keep away from heat, sparks, and open flame.
