99.9% Nano silica
Nano-silica waxay leedahay sifooyinka cabbirka qayb yar, tiro badan oo micropores ah, aag gaar ah oo weyn, content hydroxyl dusha sare, awoodda milicsiga xooggan ee iftiinka ultraviolet, iftiinka muuqda iyo iftiinka infrared. Gaar ahaan hagaajinta habka daaweynta dusha sare ee alaabta, heerka jilicsan ee agglomeration ee qaybaha nano ayaa si cad loo dhimay, iyo ku habboonaanta maadada polymer organic waa mid wanaagsan, taas oo si weyn u ballaarinaysa goobta codsiga ee alaabta.

Daawaynta wax ka beddelka dusha sare: hydrophilic, lipophilic, hydrophobic (wakiilka isku xirka KH550 KH560 KH570 A182, iwm.)
1. Alaabtani waa budo cad, aan sun ahayn oo aan dhadhamin, aan wasakhayn oo kiimiko ahaan deggan.
2. iska caabin heerkul sare ah, aag weyn oo dusha sare ah, cabbirka qayb yar.
3. Kala firdhinta wanaagsan, ka joojinta, gariirka iyo dareeraha.
4. wuxuu leeyahay thixotropy wanaagsan.
5. wuxuu leeyahay saamayn wanaagsan oo xoojin iyo dhumuc.
6. ka dib daaweynta dusha, waxay leedahay hydrophilic iyo lipophilic ka fiican.
Qadarka lagu taliyey ee alaabta lagu daray waa 0.5-2%.
