概述:E4046是主要為穩定無機顏料和有機顏料而開發的高分子分散劑。這能提供以下特點:
1、提高光澤
2、防止浮色的問題
3、提高顏料著色力
4、降低粘度
化學組成:改性聚氨酯
物理性質:活性組份:39-41%
溶劑:丁酯/甲氧基醋酸丙酯/異丁酯
胺值:17-21mg KOH/g DIN 16945
顏色:最高3 ISO 4630
應用:E4046能用于所有溶劑型涂料以及色漿中,請參見EFKA高分子分散劑的微樹脂色漿資料。
推薦用量:E4046應在研磨階段未加進顏料時加入。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%按吸油值
有機顏料:25-50%按BET值
碳黑:20%按DBP值
儲存:E4046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。
