Description

2,3-Dihydroxypropyl Methacrylate is a bifunctional monomer featuring both a polymerizable methacrylate group and two hydroxyl groups. This unique structure makes it a valuable building block for introducing hydrophilic, crosslinkable, and adhesion-promoting properties into polymer systems. It is essential for formulators and polymer chemists in industries requiring advanced material performance. The compound is supplied with full traceability under CAS No. 201594-54-9.

Application

• Hydrophilic Coatings and Inks: Used to impart water compatibility, adhesion, and flexibility in coatings for textiles, paper, and plastics.
• Crosslinking Agent for Polymers: Serves as a reactive diluent and crosslinker in acrylic and polyurethane resins, enhancing mechanical strength and chemical resistance.
• Hydrogel Synthesis: A key monomer for producing soft contact lenses, wound dressings, and other biomedical hydrogels due to its biocompatibility and water-absorbing capacity.
• Adhesive Formulations: Improves adhesion to difficult substrates (e.g., metals, glass) in structural and pressure-sensitive adhesives.
• Dental and Biomedical Materials: Incorporated into dental composites and bone cements to modify hydrophilicity and bonding characteristics.
• Surface Modification Reagent: Used to graft functional polymer brushes onto surfaces for creating anti-fog, anti-fouling, or lubricious coatings.
• Personal Care Polymers: Employed in the synthesis of fixative polymers for hairsprays and skincare products.
• Advanced Composite Materials: Functions as a coupling agent in fiber-reinforced composites to improve the interface between the matrix and reinforcement.

Quality Control

Our 2,3-Dihydroxypropyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications for polymerization-grade monomers. Certificates of Analysis (COA) documenting purity, color, water content, and inhibitor levels are provided with each shipment. We support compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. Keep away from heat, sparks, and open flame. Due to its light-sensitive nature and reactivity, it should be stored separately from strong acids and oxidizing agents. For long-term storage under inert atmosphere, please contact our technical team for specific recommendations.
