Description

2-Hydroxy-3-Phenoxypropyl Methacrylate is a specialized methacrylate monomer featuring both a reactive methacryloyl group and a pendant hydroxyl group. This bifunctional structure is critical for imparting enhanced adhesion, flexibility, and crosslinking potential to polymer systems. It is primarily sought after by formulators in the coatings, adhesives, and advanced materials sectors who require monomers that improve product performance and durability.

Application

• UV-Curable Coatings and Inks: A key reactive diluent and crosslinker in formulations for wood, plastic, and metal coatings, offering excellent cure speed and film properties.
• Adhesives and Sealants: Enhances adhesion to difficult substrates (e.g., metals, treated plastics) and improves flexibility in structural and pressure-sensitive adhesive (PSA) systems.
• Dental and Biomedical Polymers: Used in the synthesis of resins for dental composites and bone cements, where biocompatibility and mechanical strength are paramount.
• Fiber Optic Coatings: Contributes to the production of primary and secondary coatings that protect optical fibers, providing essential mechanical and environmental protection.
• Photoresists and Electronic Materials: Serves as a monomer in photopolymerizable resins for printed circuit boards (PCBs) and microelectronics.
• Modifier for Acrylic Resins: Incorporated to modify the properties of acrylic copolymers, improving impact resistance, weatherability, and solvent resistance.

Quality Control

Our 2-Hydroxy-3-Phenoxypropyl Methacrylate is manufactured under a stringent quality management system. Every batch is analyzed to ensure it meets precise chemical and physical specifications, with a typical purity of ≥97.0% (by GC/HPLC). A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, consider under an inert gas such as nitrogen.
