What is Bis(trimethoxysilylpropyl)amine?
The Uses of Bis(trimethoxysilylpropyl)amine
Bis(trimethoxysilylpropyl)amine is used in method for dyeing keratinous material, comprising the use of an organosilicon compound, an effect pigment and a film-forming polymer.
The Uses of Bis(trimethoxysilylpropyl)amine
BTMSPA and 1,2-bis(triethoxysilyl)ethane (BTESE) can be used to synthesize an amine modified mesostructured organosilica for potential applications in catalysis and absorbance. Metal finishing may be deviced by coating BTMSPA and vinyltriacetoxysilane which can be used for protection against corrosion.
General Description
Bis[3-(trimethoxysilyl)propyl]amine (BTMSPA) is a bis-amino silane which can be used as a water based coupling agent that promotes the adhesion between different materials to form a hybrid material. The amino groups in the polymer provide coating strength to the modified metal surfaces. The silanol groups bond with the hydroxyls present on the surface of metals which are further cured to give metal-siloxane linkages.
Hazard
A poison by ingestion and skin contact. A moderate skin and severe eye irritant.
