Dynasylan® VTEO
Dynasylan® VTEO is a bifunctional organosilane, boasts a reactive vinyl group and a hydrolyzable inorganic triethoxysilyl group. With its dual reactivity, Dynasylan® VTEO forms chemical bonds with both inorganic materials (e.g., glass, metals, fillers) and organic polymers (including thermosets, thermoplastics, elastomers). This compound serves as a crosslinking agent, adhesion promoter, and surface modifier, providing versatile applications.

- Reactivity
In the presence of moisture the ethoxy (Si-OCH2CH3 ) groups of Dynasylan® VTEO hydrolyze to produce ethanol and reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates or react with each other to form siloxane bonds (Si- O-Si).. The organophilic vinyl end of Dynasylan® VTEO can also react with a suitable polymer initiated by a peroxide.
