優(yōu)寶微長(zhǎng)石填料是由低含量游離二氧化硅的長(zhǎng)石精制而成，其白度自然，具有低可溶性鹽的完全化學(xué)惰性。作為
經(jīng)濟(jì)性原料，優(yōu)寶在增強(qiáng)各種工業(yè)以及養(yǎng)護(hù)涂料系統(tǒng)中效果顯著。

優(yōu)寶的顆粒堅(jiān)硬有棱角，能夠外在形成一層剛性網(wǎng)狀保護(hù)膜使生產(chǎn)出的涂料具有抗氣泡，防起霜，耐凍裂的特點(diǎn)。
將具有高硬度的優(yōu)寶加入配方當(dāng)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(qiáng)度。優(yōu)寶能夠增強(qiáng)
涂料色彩的清晰度以及持久性，廣泛運(yùn)用于各種商業(yè)，工業(yè)，船舶涂料等領(lǐng)域。

優(yōu)寶各規(guī)格產(chǎn)品之生產(chǎn)嚴(yán)格按照內(nèi)部質(zhì)量確認(rèn)體系，以確保產(chǎn)品化學(xué)純度和顆粒分布一致性達(dá)到預(yù)期要求。
