Description

2-[2,3-Bis(2-Hydroxypropoxy)Propoxy]-1-Methylethyl Acrylate is a specialized, multi-functional acrylate monomer featuring a complex polyether backbone terminated with a reactive acrylate group. This unique molecular structure provides exceptional versatility, enabling its use as a key building block in advanced polymer synthesis where flexibility, hydrophilicity, and crosslinking potential are required. It is primarily sought by formulators and researchers in the coatings, adhesives, and specialty polymer industries for developing high-performance materials with tailored properties.

Application

• UV-Curable Coatings and Inks: Serves as a reactive diluent and crosslinker, contributing to low viscosity, fast cure rates, and enhanced flexibility in the final film.
• Adhesives and Sealants: Imparts improved adhesion, toughness, and water resistance to acrylic-based pressure-sensitive and structural adhesive formulations.
• Specialty Acrylic Resins: Used as a co-monomer to introduce hydrophilic polyether segments, modifying the solubility, compatibility, and physical characteristics of acrylic copolymers.
• Hydrogel and Biomedical Polymers: Its hydrophilic nature and polymerizable acrylate group make it suitable for synthesizing crosslinked hydrogels for contact lenses, wound dressings, and drug delivery matrices.
• Fiber Optic Coatings: Contributes to the development of flexible, protective primary coatings for optical fibers due to its balance of reactivity and soft segment incorporation.
• Lithographic Printing Plates: Can be utilized in photopolymerizable compositions for creating durable and precise printing plates.

Quality Control

Our 2-[2,3-Bis(2-Hydroxypropoxy)Propoxy]-1-Methylethyl Acrylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by HPLC, determination of acid value, color, and moisture content (Karl Fischer), to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee traceability and compliance with your formulation requirements.

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). Due to its properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening. Keep away from heat, sparks, and open flames. Isolate from strong oxidizing agents and polymerization initiators.
