概述:E4330是适合于所有颜料的溶剂型高分子量分散剂。E4330在颜料分散方面的高效能具有以下特点:
1、提高颜料着色强度
2、很好的颜料稳定性,防止浮色、发花和絮凝的问题
3、降低色浆的粘度
4、提高颜料承载量
化学组成:丙烯酸嵌段共聚物
物理性质:
活性组份:69-71%
溶剂:甲氧基醋酸丙酯
胺值:26-30mg KOH/g DIN 16945
颜色:最大9 ISO 4630
外观:澄清棕色液体
应用:E4330因其与大多数树脂的相容性,而广泛用于各种溶剂型涂料,且特别适合与相容性好的分散树脂(如E1125)一起使用,生产微树脂色母浆。
推荐用量:E4330应在研磨阶段未加入颜料前加入。以下添加量是基于分散剂的活性成分对颜料量的比例:
无机颜料:10%按吸油量
有机颜料:25-50%按BET值
碳黑:20%按DBP值
储存:E4330应储存于阴凉干燥的场所。完好包装的产品质保期为从生产日期起5年,有效期限标示于包装桶上。埃夫卡EFKA分散树脂:EFKA-1016,1101,1500,1501,1502,1503;
