Description
ChangFu® DMDN22 is a versatile organosilane compound with dual functionality, making it suitable for a wide range of industrial, material science, and surface modification applications.
Features
Dual functional groups: Contains both amine and methoxy silane groups, offering unique opportunities for chemical bonding, surface modification, and adhesion.
Surface adhesion: The amine group allows for strong bonding with substrates, while the silane moiety reacts with inorganic surfaces such as glass, metal oxides, and ceramics.
Reactivity with water: The methoxy groups hydrolyze upon contact with water, leading to the formation of silanol groups that can form covalent bonds with various substrates.
Enhanced dispersion: When used as a coupling agent, this silane improves the dispersion of fillers or nanoparticles in polymer matrices, making it useful in composite materials.
