概述:E4047是穩定無機顏料和有機顏料的高分子分散劑,具有以下功能:
1、提高光澤和鮮映性(DOI)
2、減少浮色問題
3、提高顏料著色力
4、降低粘度
與E4046相比較,E4047具有更高的分子量,可以更有效的防止有機顏料和碳黑的絮凝。盡管有著較高的分子量,E4047與多種樹脂具有廣泛的相容性。用E4047研磨的色漿會比用其它EFKA高分子分散劑研磨的色漿粘度更低,并且它在純白色的調漆中也可以應用。
化學組成:改行聚氨酯
物理性質:活性組份:34-36%
溶劑:醋酸丁酯/甲氧基醋酸丙酯/異丁醇
胺值:14-20mg KOH/g DIN16945
顏色:最高4 ISO 4630
應用:E4047用于高品質工業涂料如:汽車面漆(原廠漆和修補漆)、卷鋼涂料和雙組份聚氨酯涂料體系,也可以用于研磨色漿(參見EFKA高分子分散劑的微樹脂色漿介紹)。
推薦用量:E4047在研磨階段未加入顏料前添加。按照分散劑活性組分對顏料量來計算:
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:E4047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,有效期限標于包裝桶上。埃夫卡EFKA分散樹脂:EFKA-1016,1101,1500,1501,1502,1503;
