优宝微长石填料是由低含量游离二氧化硅的长石精制而成，其白度自然，具有低可溶性盐的完全化学惰性。作为
经济性原料，优宝在增强各种工业以及养护涂料系统中效果显著。

优宝的颗粒坚硬有棱角，能够外在形成一层刚性网状保护膜使生产出的涂料具有抗气泡，防起霜，耐冻裂的特点。
将具有高硬度的优宝加入配方当中，可以增加涂料的耐磨性从而提高其防污以及耐候性。这些超白填料的低吸油
量能够在不影响涂料粘度的条件下提高其填充量，最小程度增加颜料的情况下提高涂料颜色强度。优宝能够增强
涂料色彩的清晰度以及持久性，广泛运用于各种商业，工业，船舶涂料等领域。

优宝各规格产品之生产严格按照内部质量确认体系，以确保产品化学纯度和颗粒分布一致性达到预期要求。
