Description

2-Propenoic Acid,2,18-Dihydroxy-4,7,10,13,16-Pentaoxanonadecane-1,19-Diyl Ester is a specialized acrylate-terminated oligomer, valued for its unique bifunctional structure that combines a reactive polymerizable end with a hydrophilic polyether chain. This compound is engineered to serve as a versatile building block or crosslinking agent in advanced polymer synthesis. It is particularly sought after by formulators and researchers in the coatings, adhesives, sealants, elastomers (CASE), and biomedical materials sectors seeking to enhance hydrophilicity, flexibility, and reactivity in their final products.

Application

• Hydrophilic Crosslinker for Acrylic Polymers: Imparts flexibility and moisture compatibility in coatings and films.
• Reactive Diluent/Monomer for UV-Curable Systems: Used in inks, adhesives, and protective coatings requiring fast cure and tailored surface properties.
• Biomaterial Fabrication: Serves as a precursor for hydrogels and biocompatible scaffolds in medical device and tissue engineering research.
• Modifier for Polyurethane Dispersions (PUDs): Enhances water dispersibility and film formation characteristics.
• Specialty Additive for Personal Care Polymers: Used in the synthesis of film-forming agents and fixative polymers.
• Intermediate for Functional Silicones: Acts as a grafting agent to introduce polyether and acrylate functionalities.
• Research & Development: A key intermediate for synthesizing novel amphiphilic block copolymers and dendrimers.

Quality Control

Our production of 2-Propenoic Acid,2,18-Dihydroxy-4,7,10,13,16-Pentaoxanonadecane-1,19-Diyl Ester adheres to stringent internal quality protocols to ensure batch-to-batch consistency and reliability for your formulations. Each lot is analyzed for critical parameters including purity, degree of acrylation, and residual monomers. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance and regulatory needs.

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 light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong bases and incompatible organic solvents.
