Description

3-[2-(2-Aminoethylamino)Ethylamino]Propyl-Trimethoxysilane is a high-purity, multi-functional aminosilane coupling agent with a branched triamine structure. This compound is essential for creating strong, durable covalent bonds between inorganic materials and organic polymers, significantly enhancing composite performance. It is a critical raw material for manufacturers in the adhesives, sealants, coatings, and advanced composite materials industries seeking to improve interfacial adhesion, moisture resistance, and mechanical properties.

Application

• Adhesives & Sealants: Functions as an adhesion promoter and crosslinker, improving bond strength to glass, metals, and mineral surfaces, especially in moisture-curing systems.
• Reinforced Composites: Acts as a key coupling agent for fiberglass, carbon fiber, and mineral-filled composites (e.g., epoxy, phenolic, polyamide), enhancing interlaminar shear strength and durability.
• Surface Modification: Used to treat silica, alumina, and other fillers to improve their dispersion and compatibility within polymer matrices like rubbers and engineering plastics.
• Coatings & Inks: Serves as a primer or additive to promote coating adhesion to difficult substrates and to increase corrosion and scratch resistance.
• Foundry Resins: Employed in sand casting binders to improve the strength and thermal stability of molds and cores.
• Electronics Encapsulation: Enhances the adhesion of epoxy molding compounds and potting materials to lead frames and semiconductor devices.

Quality Control

Our 3-[2-(2-Aminoethylamino)Ethylamino]Propyl-Trimethoxysilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, HPLC, and titration methods, to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to guarantee compliance with your technical 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). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture absorption.
