Description

(Methacryloxymethyl)Dimethylmethoxysilane is a specialized organosilicon monomer featuring both methacrylate and alkoxysilane functional groups in a single molecule. This unique dual functionality makes it a critical cross-linking agent and adhesion promoter in advanced polymer systems. It is essential for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance product durability, weather resistance, and substrate bonding.

Application

• Cross-linking Agent for Acrylic Polymers: Imparts enhanced mechanical strength, chemical resistance, and thermal stability to acrylic resins used in high-performance coatings and sealants.
• Adhesion Promoter: Improves the bonding of coatings, inks, and adhesives to difficult substrates such as metals, glass, and treated plastics.
• Surface Modification of Fillers: Used to treat silica, glass fibers, and other mineral fillers to improve their compatibility and dispersion in polymer matrices.
• Synthesis of Hybrid Organic-Inorganic Materials (ORMOSILs): A key monomer for creating sol-gel derived materials with tailored optical, mechanical, and surface properties.
• UV-Curable Resin Formulations: Acts as a reactive diluent and cross-linker in UV-curable systems for coatings, 3D printing resins, and graphic arts.
• Dental and Biomedical Composites: Employed in the formulation of durable, biocompatible composite materials.

Quality Control

Our production of (Methacryloxymethyl)Dimethylmethoxysilane adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and NMR to verify identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and polymerization.
