AKD Neutral Paper Sizing Chemical is a type of unsaturated lactone which is synthesized from fatty acids. Abbreviated for Alkyl Ketene Dimer, it is used to improve paperï¿½s surface condition, reduce paper machine breakdown, and to provide water resistant properties. This chemical reacts with the hydroxyl group of cellulose to form b-keto esters. AKD Neutral Paper Sizing Chemical is a waxy emulsion that disperses in the water that is stabilized by cationic starch or polyelectrolyte agent.
Facilitates water recycling in paper production process
Ideal to be used for high quality printing papers
Forms a uniform thin film on the paper
