（1）CAB-553-0.4 Eastman Cellulose Acetate Butyrate Antiblock Additive Eastman Chemical Company
产品说明:
Eastman Cellulose Acetate Butyrate (CAB-553-0.4)
Eastman cellulose esters are versatile problem solvers made from a green, sustainable and renewable resource that can be used as binders, additives, film formers or modifiers in paints, coatings, primers, lacquers and enamels for automotive, wood, plastic, paper, consumer electronics and leather applications, in graphic arts, inks and overprint varnishes. These high Tg materials provide improvements in key properties such as rheology control, dry time, appearance, metal flake orientation, sag, flow and leveling, block resistance and print resistance.
CAB-553-0.4 is soluble in low molecular weight alcohols as well as other common organic solvents. It will produce colorless films with good ultraviolet stability and is supplied as dry, free-flowing powder, offering maximum formulating convenience and flexibility.
