产品功能与特性                                                                                                                            中国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，**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*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。
