Description

2,3-Dihydroxypropyl Acrylate is a bifunctional monomer featuring both a polymerizable acrylate group and hydrophilic hydroxyl groups. This unique structure makes it a valuable building block for introducing cross-linking sites and enhancing hydrophilicity in polymer chains. It is primarily sought after by formulators and polymer chemists in the coatings, adhesives, and specialty polymer industries to create materials with tailored properties such as improved adhesion, water solubility, or reactivity.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and cross-linker to improve film flexibility, adhesion, and cure speed.
• Hydrophilic Polymers & Hydrogels: Used to synthesize polymers with enhanced water absorption for medical, agricultural, or personal care applications.
• Adhesives & Sealants: Incorporated to improve adhesion to polar substrates and adjust the rheological properties of the formulation.
• Acrylic Resin Modification: Imparts cross-linking functionality and hydroxyl groups for subsequent reactions in specialty acrylic resins.
• Bioconjugation & Drug Delivery Systems: Utilized as a linker molecule for attaching bioactive molecules to polymeric carriers due to its reactive sites.
• Photoresists & Electronic Chemicals: Acts as a monomer in polymers designed for photolithography processes in microelectronics.

Quality Control

Our 2,3-Dihydroxypropyl Acrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise specifications for polymerization-grade materials. A comprehensive Certificate of Analysis (COA) detailing purity, water content, inhibitor level, and other critical parameters is provided with every shipment to guarantee consistency and performance in your application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15°C and 25°C (59°F and 77°F). Due to its polymerizable and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and monitor inhibitor levels during prolonged storage to prevent spontaneous polymerization.
