Description

5,10,15,20,25,30,35,40-Octaoxatetratetracontane-1,44-Diyl Diacrylate is a high-purity, multi-functional acrylate monomer characterized by its extended polyether backbone. This compound matters for its unique ability to impart flexibility, hydrophilicity, and crosslinking potential into polymer networks, enhancing material properties. It is primarily needed by formulators and researchers in the advanced coatings, specialty adhesives, and photopolymer resin industries seeking to modify rheology and improve final product performance.

Application

• As a reactive diluent and flexibilizing agent in UV-curable coatings and inks for plastics and metals.
• A key monomer for synthesizing hydrophilic and crosslinked polymers used in specialty adhesives and sealants.
• In the formulation of photopolymer resins for 3D printing (SLA/DLP) and holographic recording materials.
• For modifying the properties of acrylate-based pressure-sensitive adhesives (PSAs) to adjust tack and peel strength.
• As a chemical building block in dental and medical device composites to control polymerization shrinkage and enhance biocompatibility.
• In R&D for creating functionalized surfaces and hydrogels with tailored swelling and release characteristics.

Quality Control

Our 5,10,15,20,25,30,35,40-Octaoxatetratetracontane-1,44-Diyl Diacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by HPLC and monitoring of residual monomers and inhibitors, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are available upon request to 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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, it is recommended to blanket the container with an inert gas such as nitrogen or argon and avoid exposure to heat and moisture.
