Description

α-[[3-(Trimethoxysilyl)Propoxy]Methyl]-1H-Imidazole-1-Ethanol CAS NO 149394-70-7 is a specialized organosilane coupling agent featuring a unique bifunctional structure that combines a hydrolyzable trimethoxysilyl group with an imidazole-ethanol moiety. This compound is engineered to act as a powerful adhesion promoter and surface modifier, creating durable covalent bonds between inorganic substrates and organic polymers. It is essential for manufacturers in the coatings, adhesives, and advanced composite materials industries who require enhanced material compatibility, improved mechanical properties, and long-term durability in challenging environments.

Application

• Adhesion Promoter for Coatings and Sealants: Significantly improves the adhesion of epoxy, polyurethane, and acrylic-based coatings, paints, and sealants to glass, metal, and mineral surfaces, preventing delamination.
• Surface Modification of Fillers and Pigments: Used to treat silica, glass fibers, and other inorganic fillers to enhance their dispersion and compatibility within polymer matrices, leading to superior composite performance.
• Crosslinking Agent and Catalyst: The imidazole functionality can act as a latent curing agent for epoxy resins or as a catalyst in polyurethane and other polymerization reactions.
• Primer for Metal and Glass Bonding: Applied as a thin primer layer to prepare metal (aluminum, steel) and glass surfaces for bonding with adhesives, improving bond strength and corrosion resistance.
• Fiber Sizing for Reinforced Composites: A key component in sizing formulations for glass and carbon fibers to optimize the fiber-matrix interface in high-performance composites.
• Water-based System Modifier: Facilitates the incorporation of silane chemistry into aqueous formulations for more environmentally friendly industrial processes.

Quality Control

Our production of α-[[3-(Trimethoxysilyl)Propoxy]Methyl]-1H-Imidazole-1-Ethanol adheres to a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay by titration or HPLC, verification of functional groups by FT-IR, and determination of key physical parameters. Certificates of Analysis (COA) documenting all test results are provided and can be tailored to meet specific customer or regulatory requirements.

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 reduced efficacy.
