Description

3,6,9,12,15-Pentaoxaheptadecane-1,17-Diyl Diacrylate is a high-purity, multi-functional acrylate monomer featuring a long, flexible polyether spacer chain. This unique structure provides exceptional crosslinking efficiency and imparts flexibility, hydrophilicity, and low shrinkage to cured polymer networks. It is a critical raw material for formulators seeking to enhance the performance of advanced coatings, adhesives, and photopolymer resins. Industries such as UV-curable systems, specialty polymers, and electronics rely on this compound for its reliable reactivity and ability to modify material properties.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and crosslinker, providing low viscosity, fast cure speed, and improved flexibility in wood, plastic, and metal coatings, as well as graphic arts inks.
• Adhesives & Sealants: Used in the formulation of pressure-sensitive adhesives (PSAs), structural adhesives, and anaerobic sealants to enhance tack, peel strength, and environmental resistance.
• Photopolymer Resins: A key component in stereolithography (SLA) and digital light processing (DLP) 3D printing resins, contributing to high resolution, low warpage, and tunable mechanical properties.
• Fiber Optic Coatings: Employed in primary and secondary coatings for optical fibers to provide protective, flexible layers with excellent adhesion and low signal attenuation.
• Dental & Biomedical Materials: Utilized in light-curable dental composites, restorative materials, and hydrogel matrices due to its biocompatibility and ability to form hydrophilic networks.
• Electronics Encapsulation: Serves in potting compounds and conformal coatings for electronic components, offering moisture resistance, electrical insulation, and thermal stability.
• Modifier for Acrylic Polymers: Incorporated as a co-monomer to introduce polyether segments into acrylic copolymers, improving impact resistance, weatherability, and dyeability.
