Product description

IUPAC: Dimethyl 1,4-Cyclohexanedicarboxylate

Eastman™ DMCD (Dimethyl 1,4-Cyclohexanedicarboxylate) is a low melting, cycloaliphatic diester used for the synthesis of polyester resins, polyamides, alkyds, and plasticizers. Coatings formulated with DMCD bring excellent hardness/flexibility balance and good chemical, stain, humidity, and corrosion resistance to polyester-melamine baking enamels for appliance, general metal, and automotive applications. Its outstanding hydrolytic stability makes it a good choice in waterborne polyester resins for automotive, industrial maintenance, and general metal applications. DMCD can be used to make polyester polyols for polyurethane coatings for automotive, industrial maintenance, transportation, and aerospace applications as well.

Many of these unique performance properties are similar to those offered by Eastman™ 1,4 CHDA, but unlike CHDA, the reaction of DMCD with glycols or polyols is a transesterification. Methanol, rather than water, evolves from the reaction. DMCD must be reacted in the first stage of a cook with glycols and polyols only. The first stage is processed until methanol no longer evolves, which indicates the reaction is complete. Diacid components are then added in the second stage.

Eastman™ DMCD is a mixture of cis and trans isomers. It is available as a partially crystallized liquid in drums or in molten form via tank truck.
