Product Details
特性和優點
該助劑通過對顔料的控制絮凝發揮作用。該控制絮凝作用同時可以抗流挂，防止顔料沉降以及浮色發花。
ANTI-TERRA-203 适用于中(zhōng)等極性到低極性溶劑型和無溶劑塗料體(tǐ)系，可顯著增加觸變性。用于防腐底漆時，往往可改善防腐蝕性能。ANTI-TERRA-204 是與之非常類似的産品，同時也适用于非極性體(tǐ)系。

1-2 %
二氧化钛/填料： 0.5-1 %
膨潤土： 30-50 %
上述數據爲經驗用量，極佳用量需通過一(yī)系列試驗确定。
加入方法和加工(gōng)指導
爲獲得極佳性能，應先将該助劑加入研磨料中(zhōng)，然後再加入顔料。
膨潤土漿推薦配方：
85-87 重量份溶劑
10 重量份膨潤土
5-3 重量份助劑
溶劑應爲芳烴或含芳烴的石油溶劑。如果凝膠效果不足，可加入極性溶劑以增強凝膠效果。
特别注意
在基于硝基纖維素、氯化橡膠或聚氯乙烯共聚物(wù)的塗料中(zhōng)，這些助劑可能引起變色。在矽酸酯塗料中(zhōng)，會縮短施工(gōng)時限。較高添加量時會影響環氧體(tǐ)系的施工(gōng)時限和固化反應。該助劑的胺值較高，會導緻環氧樹(shù)脂粘度上升。
