Description

2-(Triethoxy-Silyl)-Ethylamine is a bifunctional organosilane coupling agent featuring both a hydrolyzable triethoxysilyl group and a primary amine functional group. This unique structure 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 composites industries seeking to improve product durability and performance. The compound is also widely utilized as a surface modifier and a key intermediate in specialty chemical synthesis.

Application

• Adhesion Promoter: Used in paints, coatings, and adhesives to improve bonding to glass, metal, and mineral surfaces.
• Filler and Pigment Treatment: Enhances the dispersion and compatibility of silica, clay, and other fillers within polymer matrices like epoxies and polyurethanes.
• Surface Modification Agent: Imparts amino functionality to glass fibers, nanoparticles, and other substrates for further chemical grafting.
• Crosslinking Agent: Serves as a co-monomer or crosslinker in the production of silicone resins and modified polymers.
• Intermediate for Specialty Chemicals: A key building block for synthesizing more complex silane derivatives used in pharmaceuticals and agrochemicals.
• Waterborne System Modifier: Improves the stability and performance of aqueous coating and adhesive formulations.

Quality Control

Our 2-(Triethoxy-Silyl)-Ethylamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting purity, assay, and key physical properties are provided with every shipment to guarantee consistent quality and traceability for your production processes.

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). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture absorption.
