概述:E4047是稳定无机颜料和有机颜料的高分子分散剂,具有以下功能:
1、提高光泽和鲜映性(DOI)
2、减少浮色问题
3、提高颜料着色力
4、降低粘度
与E4046相比较,E4047具有更高的分子量,可以更有效的防止有机颜料和碳黑的絮凝。尽管有着较高的分子量,E4047与多种树脂具有广泛的相容性。用E4047研磨的色浆会比用其它EFKA高分子分散剂研磨的色浆粘度更低,并且它在纯白色的调漆中也可以应用。
化学组成:改行聚氨酯
物理性质:活性组份:34-36%
溶剂:醋酸丁酯/甲氧基醋酸丙酯/异丁醇
胺值:14-20mg KOH/g DIN16945
颜色:最高4 ISO 4630
应用:E4047用于高品质工业涂料如:汽车面漆(原厂漆和修补漆)、卷钢涂料和双组份聚氨酯涂料体系,也可以用于研磨色浆(参见EFKA高分子分散剂的微树脂色浆介绍)。
推荐用量:E4047在研磨阶段未加入颜料前添加。按照分散剂活性组分对颜料量来计算:
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:E4047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,有效期限标于包装桶上。埃夫卡EFKA分散树脂:EFKA-1016,1101,1500,1501,1502,1503;
