 Posté le 07/04/2020 09:52 |  | | Customized SiO2 For Adhesive Sealant |
Silicon Dioxide for Adhesives and Sealants
Nano-silica (JS-682) dispersed evenly in the adhesive and sealant, and form a silica aggregate network, the aggregate through the surface of the silanol group (Si-OH) and the polymer molecules to form hydrogen bonds , The system's mobility is limited, the viscosity of the system increases, and thus play a thickening effect, at the same time, under the action of the shear force, hydrogen bonds and silica network damage, resulting in decreased system viscosity, change effect, easy to construction, once the shear force is removed, the silica network and hydrogen bonds are re-formed. Thereby effectively preventing anti-settling during storage.
Addition of the appropriate (JS-682) to the adhesive and sealant not only improves the bond strength of the adhesive and sealant, but also extent the stability of the glue. The addition ratio is generally 0.5 to 1.5%
