Alkyl Ketene Dimer AKD CAS 144245-85-2
AKD, whose Chinese name is Alkyl Ketene Dimer, began industrialization in 1956 and was only used in special papers that required re-sizing. In recent years, cultural paper-based chemical books have been changed to AKD neutral sizing, and have found more application fields. This note introduces the main information of AKD, including its basic properties, preparation methods and processes, as well as the progress of AKD wax, AKD emulsion and surface-sizing type AKD.
