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.

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.

Bis[3-(trimethoxysilyl)propyl]amine, a silsesquioxane precursor may be used to synthesize hybrid mesostructured organosilica materials.{36}
