Description

3-Glycidoxypropyldimethoxymethylsilane is a versatile organosilicon coupling agent featuring both epoxy and alkoxysilane functional groups. This bifunctional nature makes it a critical component for enhancing adhesion and compatibility between inorganic materials and organic polymers. It is essential for manufacturers in the coatings, adhesives, and advanced composites industries seeking to improve product durability and performance. The compound is also known by its CAS number 65799-47-5.

Application

• Adhesion Promoter in epoxy, polyurethane, and acrylic-based paints, coatings, and sealants for metals, glass, and plastics.
• Surface Modifier for glass fibers, minerals, and fillers to improve their dispersion and bonding within polymer matrices like epoxy resins and silicones.
• Crosslinking Agent in silicone sealants and RTV (Room Temperature Vulcanizing) rubbers to enhance mechanical properties and environmental resistance.
• Primer Component for promoting durable bonds on difficult-to-adhere substrates such as aluminum and galvanized steel.
• Coupling Agent in the production of mineral-filled composites and engineered plastics to increase strength and reduce water absorption.
• Intermediate for the synthesis of more complex silane derivatives and specialty polymers.

Quality Control

Our production of 3-Glycidoxypropyldimethoxymethylsilane adheres to stringent quality management protocols. Every batch is analyzed using advanced techniques including Gas Chromatography (GC) and FTIR to ensure high purity and consistent performance. Comprehensive Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided and traceable to each production lot, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed under a dry, inert atmosphere (e.g., nitrogen) to prevent hydrolysis and maintain product integrity.
