Dynasylan® 1189
- CAS Number
- 31024-56-3
- Chemical Name
- N-(3-(Trimethoxysilyl)propyl)butylamine
- Chemical Family
- Amines
Dynasylan® 1189 is a bifunctional silane, boasts a reactive secondary amine and hydrolyzable methoxysilyl groups. Its dual reactivity enables chemical binding to both inorganic materials (such as glass, metals, fillers) and organic polymers (like thermosets, thermoplastics, elastomers). Serving as an adhesion promoter, surface modifier, and catalyst for substance modification, Dynasylan® 1189 contributes to versatile applications.
