Product Overview
CFS-765 (N-Phenylamino)methyltriethoxysilane CAS 3473-76-5 ND-42 is an α-aminosilane coupling agent, which is different from general amino silanes in that its amino functional group is connected to the central silicon atom through a methylene group, i.e. the amino group is connected to the α position, so it is called α-silane. At present, most of the commercial silane coupling agents are γ-silanes, i.e. their organic reaction functional groups (amino, epoxy, acryloyloxy, mercapto, etc.) are connected to the neutral silicon atom through a propylidene, i.e. the organic reaction functional group is in the γ-position of the propylidene.

The amino group of silane coupling agent CFS-765 (CAS 3473-76-5) is a negative electron giving body, and since it is close to the central silicon atom, the free electron pair of nitrogen on its amino group has a greater attractive force on the silicon atom, which weakens the force of the silicon atom on the three ethoxyl groups. Therefore, the ethoxy group on the silane coupling agent CFS-765 (CAS 3473-76-5) is more easily aqueous, and the speed of its hydrolysis reaction is much faster than that of ordinary γ-aminosilane, with higher reactivity and faster curing of products.

 The molecular structure of silane coupling agent CFS-765 (CAS 3473-76-5) has a primary amino functional group and three hydrolyzable alkoxy-ethoxy groups, and this dual reactivity allows silane coupling agent CFS-765 (CAS 3473-76-5) to improve the bonding, bonding and compatibility between inorganic materials (glass, metals, fillers) and organic polymers (thermosets This dual reactivity allows CFS-765 (CAS 3473-76-5) to improve the bonding, adhesion and compatibility between inorganic materials (glass, metal, filler) and organic polymers (thermosetting resins, plastics, elastomers) through a bidirectional chemical reaction, thereby improving the mechanical properties of resin-based composites or improving the bonding strength and water resistance of resin coatings. In different applications, silane coupling agentCFS-765 (CAS 3473-76-5) can be used as coupling agent, adhesion promoter, curing agent, surface modifier of color filler, etc.
