該助劑特别推薦用(yòng)于不飽和聚酯樹脂、膠衣、丙烯酸、聚氨酯和環氧樹脂，在所有(yǒu)應用(yòng)領域都表現出了最高效的性能(néng)。
建議用(yòng)量
0.5-1.5%助劑（購(gòu)入形式）基于填料。
以上推薦添加量供參考，最佳添加量需經過一系列試驗确定。
加入方法及加工(gōng)指導
為(wèi)了獲得最佳性能(néng)，助劑應當在添加固體(tǐ)物(wù)料之前加入。
塗料工(gōng)業
特性和優點
該助劑可(kě)提供一種所希望的、顔料的受控絮凝，這一體(tǐ)系在各個顔料顆粒之間架起橋梁，從而形成三維網絡結構。顔料的這種受控絮凝有(yǒu)效防止了浮色發花(huā)以及沉降和流挂。
