Product Description
Eastman™ DB Acetate (Diethylene Glycol Monobutyl Ether Acetate) is a high boiling glycol ether ester widely used in printing inks, high-bake enamels, and as a coalescing aid in low pH latex paints. Eastman™ DB Acetate is especially useful in screen inks and as a retarder solvent in coil coatings. It has application as a selective solvent in the separation of alcohols and ketones by distillation.
