Bis[3-(trimethoxysilyl)propyl]amine Description

Bis[3-(trimethoxysilyl)propyl]amine (BTMSPA) (CAS 82985-35-1) is a bis-amino silane used as a water-based coupling agent. It enhances adhesion between different materials, facilitating the formation of hybrid materials. The amino groups provide coating strength to modified metal surfaces, while the silanol groups bond with the hydroxyl groups on metal surfaces, forming durable metal-siloxane linkages upon curing.
