N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane: A Versatile Silane Coupling Agent

N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane, also known as N-[3-(trimethoxysilyl)propyl]ethylenediamine, is a silane coupling agent with two amino groups and three methoxy groups. It has the chemical formula C8H22N2O3Si and the CAS number 1760-24-3.

Silane coupling agents are compounds that can form a bridge between organic and inorganic materials, such as polymers and metal oxides. They can improve the adhesion, compatibility, and durability of composite materials by creating covalent bonds between the different phases.

N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane is a versatile silane coupling agent that can react with various functional groups, such as carboxyl, epoxy, isocyanate, and acrylate. It can also act as a crosslinking agent or a curing agent for epoxy resins and polyurethanes.

Some of the applications of N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane include:

  • Surface modification of silica, alumina, and other metal oxides to improve their dispersion and compatibility with polymers.
  • Adhesion promotion of epoxy, acrylic, and urethane coatings to metal substrates.
  • Preparation of amino-functionalized silica nanoparticles for biomedical applications.
  • Synthesis of hybrid materials with enhanced mechanical, thermal, and optical properties.

N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane is available from Sigma-Aldrich in various pack sizes and purity grades. It has a pH of 10 (10 g/l, H₂O, 20 °C) and a density of 1.01 g/ml at 25 °C. It should be stored in a cool and dry place, away from moisture, heat, and light. It should be handled with care as it may cause skin and eye irritation, allergic reactions, and respiratory problems. It is also toxic to aquatic life.
