Description

3-[Bis(2-Methoxyethoxy)Methylsilyl]Propyl Methacrylate is a specialized organosilane methacrylate monomer featuring a unique hybrid structure. This compound is engineered to act as a coupling agent, effectively bridging organic polymers with inorganic substrates like glass, metals, and silica. It is essential for industries requiring advanced materials with enhanced adhesion, durability, and specific surface properties. The product is identified by CAS NO 93804-26-3.

Application

• Surface Modification Agent: Used to functionalize glass fibers, fillers (e.g., silica, alumina), and metal oxides to improve compatibility with polymer matrices in composites.
• Adhesion Promoter in Coatings: Enhances the bond strength and wet adhesion of acrylic, epoxy, and polyurethane coatings on difficult-to-adhere substrates like metals and glass.
• Dental & Medical Material Component: Serves as a key monomer in dental composite resins and bone cements, improving filler-matrix bonding and material strength.
• Silicone Hybrid Polymer Synthesis: Employed in the synthesis of silicone-modified acrylic resins for applications requiring flexibility, weatherability, and low surface energy.
• Optical & Electronic Encapsulants: Used in formulations for LED encapsulants and optical adhesives where stable bonding to glass and metals under thermal stress is critical.
• Release Coatings & Pressure-Sensitive Adhesives (PSAs): Modifies surface properties to create controlled release interfaces or to tailor the adhesive performance of acrylic PSAs.

Quality Control

Our production of 3-[Bis(2-Methoxyethoxy)Methylsilyl]Propyl Methacrylate adheres to stringent quality management protocols. Each batch undergoes comprehensive analysis, including assay (by GC/HPLC), identity confirmation (IR, NMR), and purity verification to ensure consistency and performance. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified on the label to maximize shelf life. This material is hygroscopic (moisture-sensitive); containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
