Description

(Methacryloxymethyl)Methyldiethoxysilane is a versatile organosilicon monomer featuring both methacrylate and hydrolyzable ethoxysilyl functional groups. This dual functionality is critical for creating durable covalent bonds between organic polymers and inorganic substrates like glass, metals, or minerals. It is essential for formulators and material scientists seeking to enhance adhesion, cross-linking density, and surface modification in advanced composites and coatings.

Application

• Coupling Agent for Acrylic Composites: Enhances the bond between acrylic resins (e.g., PMMA) and mineral fillers or glass fibers, improving mechanical strength and durability.
• Surface Primers and Adhesion Promoters: Used in coatings and inks for glass, metals, and plastics to dramatically improve wet and dry adhesion.
• Cross-linking Agent for Silicone Modifications: Serves as a reactive site to graft methacrylate functionalities onto siloxane backbones for UV-curable or toughened silicone materials.
• Fiber Treatment for Reinforced Plastics: Applied as a sizing or finish on glass or carbon fibers to optimize the fiber-matrix interface in thermoset and thermoplastic composites.
• Synthesis of Hybrid Organic-Inorganic Materials (ORMOSILs): A key precursor in sol-gel chemistry for producing transparent, scratch-resistant, or functional hybrid coatings.
• Dental and Biomedical Materials: Incorporated into resin-based composites and adhesives to improve bonding to tooth enamel or ceramic prosthetics.
• Waterproofing and Stone Consolidation: Used in treatments for concrete, masonry, and natural stone to impart water repellency and strengthen porous structures.
• Electronic Encapsulants and Potting Compounds: Improves the adhesion and environmental resistance of protective resins used in electronic assemblies.

Quality Control

Our production of (Methacryloxymethyl)Methyldiethoxysilane adheres to a stringent quality management system. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and polymerization. Keep away from heat, sparks, and open flame.
