Product Overview
Eastman™ CHDM-D is a symmetrical cycloaliphatic glycol used in the manufacturing process for saturated and unsaturated polyester resins. CHDM-D provides good resistance for chemical, stain, humidity & corrosion in polyester-metlamine baked enamels.

CHDM-D is often used in conjunction with Eastman NPG™ as a glycol modifier for resins.
