優寶微長石填料是由低含量游離二氧化硅的長石精制而成，其白度自然，具有低可溶性鹽的完全化學惰性。作為
經濟性原料，優寶在增強各種工業以及養護涂料系統中效果顯著。

優寶的顆粒堅硬有棱角，能夠外在形成一層剛性網狀保護膜使生產出的涂料具有抗氣泡，防起霜，耐凍裂的特點。
將具有高硬度的優寶加入配方當中，可以增加涂料的耐磨性從而提高其防污以及耐候性。這些超白填料的低吸油
量能夠在不影響涂料粘度的條件下提高其填充量，最小程度增加顏料的情況下提高涂料顏色強度。優寶能夠增強
涂料色彩的清晰度以及持久性，廣泛運用于各種商業，工業，船舶涂料等領域。

優寶各規格產品之生產嚴格按照內部質量確認體系，以確保產品化學純度和顆粒分布一致性達到預期要求。
