概述:E4330是適合于所有顏料的溶劑型高分子量分散劑。E4330在顏料分散方面的高效能具有以下特點:
1、提高顏料著色強度
2、很好的顏料穩定性,防止浮色、發花和絮凝的問題
3、降低色漿的粘度
4、提高顏料承載量
化學組成:丙烯酸嵌段共聚物
物理性質:
活性組份:69-71%
溶劑:甲氧基醋酸丙酯
胺值:26-30mg KOH/g DIN 16945
顏色:最大9 ISO 4630
外觀:澄清棕色液體
應用:E4330因其與大多數樹脂的相容性,而廣泛用于各種溶劑型涂料,且特別適合與相容性好的分散樹脂(如E1125)一起使用,生產微樹脂色母漿。
推薦用量:E4330應在研磨階段未加入顏料前加入。以下添加量是基于分散劑的活性成分對顏料量的比例:
無機顏料:10%按吸油量
有機顏料:25-50%按BET值
碳黑:20%按DBP值
儲存:E4330應儲存于陰涼干燥的場所。完好包裝的產品質保期為從生產日期起5年,有效期限標示于包裝桶上。埃夫卡EFKA分散樹脂:EFKA-1016,1101,1500,1501,1502,1503;
