Chemical methods of wet end contaminant control are frequently used in the paper industry to improve machineproductivity and paper quality. Three quite different methods are particularly common:

• Stabilizing the colloidal material with a dispersant or surfactant
• Reducing the tackiness of the colloidal material using a detackifier
• Removing the contaminants from the system together with the paper using a highly charged cationic polymer
