Description

1-Methyl-2-(Trimethoxysilyl)Ethyl Methacrylate is a specialized organosilane methacrylate monomer that combines the reactivity of a methacrylate group with the functionality of a hydrolyzable trimethoxysilyl group. This dual functionality makes it a critical coupling agent and adhesion promoter in advanced polymer systems. It is essential for formulators and manufacturers in the coatings, adhesives, and advanced composites industries seeking to enhance the bonding between organic polymers and inorganic substrates.

Application

• Adhesion Promoter for Coatings: Significantly improves the adhesion of acrylic, epoxy, and polyurethane coatings to glass, metals, and mineral surfaces.
• Crosslinking Agent for Silicone-Modified Polymers: Used in the synthesis of moisture-curable resins and sealants for enhanced durability and weather resistance.
• Surface Modification of Fillers: Treats silica, glass fibers, and other inorganic fillers to improve compatibility and dispersion in polymer matrices for reinforced plastics and composites.
• Dental and Biomedical Materials: Serves as a key component in silane-based primers and adhesive systems for dental composites and certain biomedical devices.
• Fiber Optic Coatings: Used in coatings for optical fibers to protect the glass cladding and ensure signal integrity.
• Automotive and Industrial Sealants: Imparts excellent water resistance and long-term adhesion in high-performance sealant formulations.

Quality Control

Our production of 1-Methyl-2-(Trimethoxysilyl)Ethyl Methacrylate adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed via GC, HPLC, and FTIR to confirm identity, assay, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing purity, specific gravity, refractive index, and moisture content is provided with every 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 area at temperatures between 15-25°C (59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and polymerization. Isolate from heat, sparks, and open flame.
