Eastman™ Cellulose Acetate Butyrate (CAB-171-15)
Eastman™ cellulose esters (CAB, CAP, and CA) are versatile problemsolvers made from a green, sustainable and renewable resource thatcan be used as binders, additives, film formers or modifiers inpaints, coatings, primers, lacquers and enamels for automotive,wood, plastic, paper, consumer electronics and leatherapplications, in graphic arts, inks and overprint varnishes. Thesehigh Tg materials provide improvements in key properties such asrheology control, dry time, appearance, metal flake orientation,sag, flow and leveling, block resistance and print resistance.
CAB-171-15 has the lowest butyryl content and the lowest degree ofsolubility in the Eastman™ cellulose ester family. Films preparedwith this ester offer superior toughness and hardness when comparedwith films prepared from other mixed esters.
醋酸丁酸纤维素应用：
1、CAB加入金属涂料中,可加速溶剂从漆膜中释放,缩短触干时间;
2、CAB作为流平剂,可改善流平性,消除漆膜缩孔;
3、CAB加入塑料涂料中,能增强耐磨性、颜色稳定性,增加韧性;
4、在汽车底漆中加入CAB有助于溶剂挥发时更好的促使底漆的收缩和铝粉的定向排列;
5、在汽车修补漆体系中加入,能缩短干燥时间,提高抗冷裂性,并具有良好的抛光性能;
6、CAB加入清漆后,能加强附着力、光泽性和保光性,使体系又有交联特性又有干燥速度。
