Eastman Cellulose Ester Selector Guide

Choose your desired solution below.

Eastman cellulose esters are bio-based polymers used as film formers, resin modifiers, and additives primarily used to formulate high performance coatings and inks used in a variety of industries. Improvements they bring to formulations range from reduced dry-to-touch time, improved leveling, increased gloss, enhanced UV stability, and optimized metallic pigment orientation.

These polymers vary by ester composition, hydroxyl content, and molecular weight, and more. These properties influence the ester’s degree of solubility, hardness, resin compatibility which permit the customization of each formulation’s requirements. To select the best grade for your application, begin by selecting the ester composition you want.
