Description

3,6,9,12,15,18,21,24-Octaoxahexacosane-1,26-Diyl Diacrylate is a high-purity, multi-functional diacrylate monomer characterized by a long, flexible polyether spacer chain. This unique structure is critical for imparting flexibility, hydrophilicity, and enhanced reactivity in advanced polymer formulations. It is an essential building block for manufacturers in the photopolymer, specialty coatings, and advanced materials sectors seeking to fine-tune the physical properties of their end products.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and crosslinker to improve flexibility, adhesion, and cure speed in formulations for wood, plastic, and metal substrates.
• Photopolymer Resins: A key monomer in stereolithography (SLA) and digital light processing (DLP) 3D printing resins, contributing to low shrinkage and high-resolution, tough final parts.
• Adhesives & Sealants: Used in the synthesis of pressure-sensitive adhesives (PSAs) and anaerobic sealants to enhance bond strength and environmental resistance.
• Hydrogel & Biomedical Materials: Employed in the production of hydrophilic, cross-linked networks for contact lenses, wound dressings, and drug delivery systems.
• Fiber Optic Coatings: Imparts necessary flexibility and protective properties to primary and secondary coatings for optical fibers.
• Lithographic Printing Plates: Acts as a photopolymerizable component in the production of flexible printing plates, offering excellent durability and image reproduction.

Quality Control

Every batch of 3,6,9,12,15,18,21,24-Octaoxahexacosane-1,26-Diyl Diacrylate is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing, including assay, impurity profiling, and physical characterization, to ensure compliance with industry standards and consistent performance. Certificates of Analysis (COA) detailing purity, inhibitor content, and other critical parameters are available upon request.

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 nature and tendency to be easily oxidized, it is recommended to store this material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize premature polymerization. Keep away from heat, sparks, and open flames.
