This "nano-coating" is 20 times as expensive as traditional glazes. But in terms of function, the nano-coating, applied in a thin layer above the traditional coating, is effective in filling the holes in the coating, which becomes so smooth that even a pencil won't leave a mark. Naturally germs and dust won't be able to settle there.
就成本來說，奈米塗料是傳統塗料的二十倍，就功能來說，奈米級釉料極精細，噴在傳統釉料上，可以有效填補釉料上的坑洞，讓表面光滑細緻，連鉛筆芯刮過都了無痕跡，細菌及灰塵自然也沒有可以立足之處。
