γ-Aminopropyltriethoxysilane (LT-550)
Class: Coupling agent series
CAS NO: 919-30-2
Structural formula:
Descr1ption
LT-550 is a bifunctional silane possessing a reactive primary amino group and hydrolyzable ethoxysilyl groups. The dual nature of its reactivity allows it to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermoplastics, thermosets, elastomers) thus functioning as an adhesion promoter, cross-linker, and/or surface modifier. It also greatly increases water (vapor) and corrosion resistance.
LT-550 is a clear, colorless low-viscosity liquid with a characteristic amine odor. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons. In addition, it is completely and immediately soluble in water (with reaction).
