Equinox® Stabilizer is a unique product which ensures controlled availability of halogen during the paper-making process. By reducing interactions with sources of active halogen demand, Equinox® Stabilizer reduces the quantity of sodium hypochlorite used for slime control and maximizes compatibility with sensitive process additives (including optical brighteners, retention aids, wet and dry strength aids).
Drawing upon decades of experience in biocide treatment and halogen stabilization, Sigura™ developed Equinox® Stabilizer , a DMH-based (5, 5-dimethylhydantoin) halogen stabilizer to optimize halogen availability in papermaking operations. This solution enables paper and paperboard producers with an increased biocidal efficacy of chlorine, with minimal negative side effects such as corrosion and interference with other chemical additives. In addition, Equinox® Stabilizer is considered non-hazardous and does not require special handling procedures or licenses. When used in combination with hypochlorite, Equinox® Stabilizer offers multiple benefits:

Any factors that risk downtime to operations or disruption of sensitive chemical processes in continuous papermaking production lines can be costly in terms of lost productivity or detrimental effects on product quality. It is imperative to discourage biofilm growth that can foul equipment surfaces, create hazardous working conditions, contaminate paper products, or produce visible stains that compromise product quality. Biofilm control is only one part of the story. It is also important to optimize that control without incurring additional financial and operational problems in the process.
