Description

(Diphenylsilylene)Bis(Oxy-2,1-Ethanediyl) Bismethacrylate is a specialized organosilicon cross-linking agent featuring a central diphenylsilylene core flanked by two methacrylate-terminated ethylene glycol chains. This compound matters for its unique ability to act as a reactive monomer or cross-linker, introducing siloxane linkages and polymerizable methacrylate groups into advanced material matrices. It is primarily needed by manufacturers in the polymer, specialty coatings, and advanced resin industries seeking to enhance thermal stability, adhesion, and mechanical properties.

Application

• As a key cross-linking monomer in the synthesis of high-performance, heat-resistant silicone-acrylic hybrid polymers and resins.
• In the formulation of advanced optical materials, including specialty lenses and light-guiding components, where its structure contributes to precise refractive index tuning.
• For the development of durable, scratch-resistant, and weatherable coatings for automotive, aerospace, and industrial applications.
• As a surface-modifying agent or adhesion promoter in composite materials to improve bonding between organic polymers and inorganic substrates.
• In the production of dental restorative materials and biocompatible polymers, leveraging its potential for creating stable, cross-linked networks.
• For research and development of novel photopolymerizable systems used in 3D printing (additive manufacturing) and photoresists.

Quality Control

Our production of (Diphenylsilylene)Bis(Oxy-2,1-Ethanediyl) Bismethacrylate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency meet exacting standards. A Certificate of Analysis (COA) detailing specific batch results is provided with each shipment to support your quality assurance and regulatory needs.

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). This material is light-sensitive and easily oxidized; for long-term storage, it is recommended to keep the container under an inert atmosphere (e.g., nitrogen or argon) to maintain optimal stability and prevent polymerization or degradation.
