99.9% Nano silika
Nano-silica ili ndi mawonekedwe a tinthu tating'onoting'ono, kuchuluka kwa ma micropores, malo akuluakulu apadera, kuchuluka kwa hydroxyl pamwamba, mphamvu yowunikira kwambiri ku kuwala kwa ultraviolet, kuwala kowoneka ndi kuwala kwa infrared. Makamaka ndi kusintha kwa njira yochizira pamwamba pa chinthucho, kuchuluka kwa tinthu tating'onoting'ono ta nano kumachepa, ndipo kugwirizana ndi zinthu za organic polymer kumakhala bwino, zomwe zimakulitsa kwambiri gawo logwiritsira ntchito chinthucho.

Chithandizo chosintha pamwamba: chokonda madzi, chokonda lipophilic, chokonda madzi (chothandizira cholumikizira KH550 KH560 KH570 A182, ndi zina zotero)
1. Chogulitsachi ndi ufa woyera, sichili ndi poizoni komanso chopanda kukoma, sichimaipitsa komanso chimakhala chokhazikika pa mankhwala.
2. Kukana kutentha kwambiri, malo akuluakulu pamwamba, kukula kwa tinthu tating'onoting'ono.
3. Kufalikira bwino, kuyimitsidwa, kugwedezeka ndi kusungunuka kwa madzi.
4. ali ndi thixotropy yabwino.
5. ili ndi mphamvu yabwino yolimbitsa ndi kukhuthala.
6. Pambuyo pokonza pamwamba, imakhala ndi hydrophilic komanso lipophilic yabwino.
Kuchuluka kovomerezeka kwa zinthu zomwe zawonjezeredwa ndi 0.5-2%.
