N-[3-(Trimethoxysilyl)propyl]ethylenediamine Usage And Synthesis

Uses

This substance is used in the following products: adhesives and sealants, coating products and finger paints. Other release to the environment of this substance is likely to occur from: indoor use and outdoor use resulting in inclusion into or onto a materials (e.g. binding agent in paints and coatings or adhesives).

service life

Other release to the environment of this substance is likely to occur from: outdoor use in long-life materials with low release rate (e.g. metal, wooden and plastic construction and building materials) and indoor use in long-life materials with low release rate (e.g. flooring, furniture, toys, construction materials, curtains, foot-wear, leather products, paper and cardboard products, electronic equipment).

Introduction

N-[3-(Trimethoxysilyl)propyl]ethylenediamine (equal to A-1120, GF 91, KBM603) is a clear, colorless, strongly alkaline liquid with smell being very sensitive to hydrolysis. The chloride content ranges in the lower ppm-level.
N-[3-(Trimethoxysilyl)propyl]ethylenediamine is used as adhesion promoter at organic/inorganic interfaces, for modification of surfaces (corrosion prevention, component of primers) or silicone-polymers or as crosslinker (moisture crosslinking of polymers). The application as "coupling agent" leads in general to an improvement of mechanical and electrical product properties above all under exposure to heat and/or moisture. Applications:

  • N-[3-(Trimethoxysilyl)propyl]ethylenediamine may be used as an effective coupling agent for clay reinforced elastomers such as natural and nitrile rubber, to improve physical and dynamic properties.
  • Used as an effective coupling agent for mineral reinforced nylon 6, nylon 6/6 and polybutyleneterephthalate, to increase the flexural and tensile strength of the thermoplastic composite.
  • Used as a fiberglass finish or a resinous additive for fiberglass reinforced phenolic, melamine and expoxy thermoset composites.
  • Used as a mineral binders in in foundry and abrasive composite applications, to improve adhesion, increase composite strength.
  • Used as a glass and metal primer, to improve the adhesion of many coatings (urethanes, epoxies, phenolics and others) to glass and metal surfaces.
  • Used as an adhesion promoters in polysulfide, polyvinyl chloride plastisol, silicone two part urethane and epoxy adhesives and sealants.

Chemical Properties

Colorless transparent liquid

Uses

N-[3-(Trimethoxysilyl)propyl]ethylenediamine has also been used as an organic ligand for the surface modification of silica gel to uptake heavy metal ions. It can react with fluorinated carbon nanotubes (F-CNT) to form aminoalkylalkoxysilane functionalized carbon nanotubes.

Uses

  • [3-(2-Aminoethylamino)propyl]trimethoxysilane has been used in the synthesis of various polyhedral silsesquioxanes, (RSiO1.5)n (SSQO).
  • It can be functionalized onto the mesoporous SBA-15 silica to be used as matrices for controlled drug delivery.
  • It is also used in the synthesis of silane-based polymer, which is used in conducting instant adhesives.
