Ns-a25 Hydrophilic Nano-silica

These NS-A25 Hydrophilic Nano-Silica is a new product which is developed by our company for special field of application in the basis of technology of high pure nano silica. In the circumstance of liquid phase, its dispersibility is better, and function is more outstanding. The production is deal with by adding acid and additive subsection, so that could control the creating and developing granule, and break the interaction of hydroxy of the surface of silica granule, and prevent the unite of granule.
NS25 Nano Silica added to different system without changing original formula of technology could increase different kinds of function abviously. The surface of NS33 Nano silica has many unsaturated chemical bond and surface hydroxyl of different bonding state, which increases compound systema s tenacity and intensity while complexing with other products of different system.
