Stickies Control Agent (Cationic Fixative)
Stickies control agents are cationic polymers or specialized dispersants used to passivate and fix sticky contaminants (pressure-sensitive adhesives, hot melts, and coatings residues) in recycled fiber systems. They prevent stickies from depositing on paper machine fabrics, rolls, and wires, which cause sheet defects, breaks, and costly cleaning downtime. These agents are critical for mills using high proportions of recovered paper furnish.
