Adhesive control enzymes – a more cost-effective alternative to traditional adhesive control agents.

Hazards of adhesives

• Deposits on the forming wire make filtration difficult, increasing downtime for cleaning.

• Deposits on the press felt and rollers shorten the felt's lifespan.

• Adhesion to the drying cylinder surface causes paper breakage.

• Residue in the paper forms stains, increasing paper defects.

• Accumulate in the white water, becoming "anionic waste," affecting the effectiveness of cationic additives.

Adhesive-controlling enzymes – the mechanism of adhesive treatment

Since most adhesives contain a large number of ester bonds, which connect the basic structure of the adhesive, esterases can break and destroy these ester bonds, thereby reducing its viscosity and making it difficult for it to repolymerize in the system, thus achieving the purpose of degradation, anti-agglomeration, and anti-deposition.
