Producer:
Eastman IUPAC: 1,4-cyclohexanedimethanoEastman™ CHDM-D90 is a 90/10 weight percent solution of CHDM-D in water. It is a liquid at room temperature for easier handling. This symmetrical, high molecular weight cycloaliphatic glycol is used to make saturated and unsaturated polyester resins. It is commonly used as a glycol modifier for resins containing Eastman NPG™ glycol. The 10 weight percent water in CHDM-D90 is removed during heating of the resin reaction mixture.Good chemical, stain, humidity, and corrosion resistance is achieved when using CHDM-D90 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-D90 is a mixture of cis and trans isomers.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).
