Description

(1-Methylethylidene)Bis(4,1-Phenyleneoxy-3,1-Propanediyl) Bismethacrylate is a high-purity, difunctional methacrylate monomer characterized by its extended aromatic and flexible ether-containing backbone. This compound is valued for its ability to impart enhanced cross-linking density, thermal stability, and mechanical properties to polymer networks. It is primarily sought by formulators and researchers in the advanced photopolymer, specialty coating, and high-performance adhesive industries, where it serves as a critical building block for creating tailored polymeric materials.

Application

• Photopolymer Resins: A key monomer in UV-curable systems for 3D printing (stereolithography/SLA and digital light processing/DLP), coatings, and inks, contributing to rapid curing and excellent final material properties.
• Dental & Medical Polymers: Used in the formulation of high-strength, biocompatible dental composites, crown & bridge materials, and bone cements.
• Optical Materials: Employed in the production of optical lenses, waveguides, and other transparent polymer components requiring precise refractive index and low shrinkage.
• Electronics Encapsulation: Functions as a cross-linking agent in potting compounds and encapsulants for electronic components, providing environmental protection and structural integrity.
• Specialty Adhesives & Sealants: Enhances the performance of anaerobic, acrylic, and structural adhesives by improving toughness, chemical resistance, and bond strength.
• Composite Matrices: Acts as a reactive diluent and cross-linker in fiber-reinforced polymer (FRP) composites for aerospace, automotive, and marine applications.
