Product Details
特性和优点
该助剂通过对颜料的控制絮凝发挥作用。该控制絮凝作用同时可以抗流挂，防止颜料沉降以及浮色发花。
ANTI-TERRA-203 适用于中等极性到低极性溶剂型和无溶剂涂料体系，可显著增加触变性。用于防腐底漆时，往往可改善防腐蚀性能。ANTI-TERRA-204 是与之非常类似的产品，同时也适用于非极性体系。

膨润土： 30-50 %
上述数据为经验用量，极佳用量需通过一系列试验确定。
加入方法和加工指导
为获得极佳性能，应先将该助剂加入研磨料中，然后再加入颜料。
膨润土浆推荐配方：
85-87 重量份溶剂
10 重量份膨润土
5-3 重量份助剂
溶剂应为芳烃或含芳烃的石油溶剂。如果凝胶效果不足，可加入极性溶剂以增强凝胶效果。
特别注意
在基于硝基纤维素、氯化橡胶或聚氯乙烯共聚物的涂料中，这些助剂可能引起变色。在硅酸酯涂料中，会缩短施工时限。较高添加量时会影响环氧体系的施工时限和固化反应。该助剂的胺值较高，会导致环氧树脂粘度上升。
