IUPAC: 1,4-cyclohexanedimethanolEastman™ CHDM-D is a symmetrical, high molecular weight cycloaliphatic glycol used to make saturated and unsaturated polyester resins. It is commonly used as a glycol modifier for resins containing Eastman NPG™ glycol. Good chemical, stain, humidity, and corrosion resistance is achieved when using CHDM-D in polyester-melamine baking enamels for appliance, general metal, and automotive coatings. It delivers good hydrolytic stability to waterborne polyester resins. Durable polyester polyols for polyurethane coatings can be made for the industrial maintenance, transportation, automotive, and aerospace markets. It can also be used in unsaturated polyester resins for gel coats, sheet molding compounds, and injection moldable fiberglass-reinforced plastics.Eastman™ CHDM-D is a mixture of cis and trans isomers. It is available in three forms: Cast solid in drums requiring a hot room or drum heater to melt the contents for removal. Bulk molten which requires a heated storage tank. CHDM-D90, a 90/10 weight percent solution of CHDM-D in water, which is liquid at room temperature for easier handling.Contact us for more information, to request a sample, or to receive a copy of Eastman publication, Storage and Handling of 1,4-Cyclohexanedimethanol (CHDM).
