Description

Phenylenebismethylene Bismethacrylate is a high-purity, difunctional methacrylate monomer characterized by its rigid aromatic core. This compound is essential for creating advanced polymer networks with enhanced thermal stability, mechanical strength, and crosslink density. It is primarily sought by formulators and researchers in the photopolymer, dental materials, advanced composites, and specialty coatings industries for developing high-performance end products.

Application

• Photopolymer Resins: A key crosslinking agent in UV-curable inks, coatings, and 3D printing (stereolithography) resins, contributing to rapid curing and excellent final material properties.
• Dental Restorative Materials: Used in dental composites and adhesives to improve wear resistance, hardness, and dimensional stability.
• Fiber-Reinforced Composites: Serves as a matrix resin component for high-performance composites in aerospace and automotive applications, offering high glass transition temperatures.
• Optical Lenses and Waveguides: Employed in the formulation of optical polymers due to its ability to form clear, rigid networks with good light transmission.
• Adhesives and Sealants: Enhances the heat resistance and structural integrity of industrial-grade anaerobic and structural adhesives.
• Lithographic Printing Plates: Acts as a crosslinker in photopolymerizable compositions for printing plates, ensuring high durability and fine image reproduction.

Quality Control

Our Phenylenebismethylene Bismethacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting requirements of advanced material synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from strong acids, bases, and sources of ignition. For long-term storage under inert atmosphere (nitrogen or argon) is recommended to prevent premature polymerization.
