Description

3,6,9,12-Tetraoxatetradecane-1,14-Diyl Diacrylate is a high-purity, difunctional acrylate monomer characterized by its tetraethylene glycol spacer. This compound matters for its unique combination of flexibility, reactivity, and hydrophilicity, making it an essential crosslinking agent and polymer building block. It is primarily needed by formulators and researchers in the advanced coatings, adhesives, and specialty polymer industries seeking to enhance material properties.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and crosslinker to improve flexibility, adhesion, and cure speed in formulations for electronics, optical fibers, and overprint varnishes.
• Adhesives & Sealants: Used to synthesize pressure-sensitive adhesives (PSAs) and structural adhesives requiring a balance of tack, peel strength, and low-temperature performance.
• Hydrogel Synthesis: Serves as a crosslinking agent in the production of hydrophilic hydrogels for biomedical applications, including contact lenses, wound dressings, and drug delivery systems.
• Photopolymer Resins: A key monomer in resins for stereolithography (SLA) and digital light processing (DLP) 3D printing, contributing to part toughness and resolution.
• Fiber Optic Coatings: Imparts essential mechanical and environmental protection properties as a component in primary and secondary coatings for optical fibers.
• Modifier for Polyurethanes & Polyesters: Incorporated to introduce acrylate functionality, enabling subsequent UV curing or improving compatibility in polymer blends.
