Biological Deposit Control All Paper Production Chlorine for the incoming water Organic products for the stock systems Organic products for the additives
Retention Aids All Paper Production Generally polymeric agents to improve the retention of fiber and filler in the sheet.
Defoamers All Paper Production Defoamers and anti foamers Both have uses in Paper Production
Roll Treatment Recycled and Newsprint Production Mixture of surfactants, polymers and inorganic deposit control chemicals that maintain roll surfaces clean of stickies and pitch
Wire Passivators For all Paper production A mixture of cationic polymers with hydrophobic properties that is sprayed onto the forming fabric to prevent the permanent accumulation of stickies

Pitch Control Mostly Pulp production and Newsprint Mixtures of Polymers and dispersants that prevent the small pitch particles from accumulating and then fixing these small particles to the fiber
Stickie Control Recycled Paper Production Mixture of special surfactants and polymers that maintain stickies in a dispersed state and then affix these stickies to the surface of the fibers
Boil Out Programs For all Paper production Alkaline productions for most applications Acid Products for Carbonate scales Chelant mixtures for Barium scales
Felt Conditioning For all Paper production Batch cleaning and conditioning Generally alkaline based products with surfactants and solvents tailored to the contaminants
Soiled Wet Felt showing stickies
Cleaned wet felt
Felt Conditioning For all Paper production Continuous cleaning and conditioning Alkaline, neutral and acid products specially tailored for the PM and the contaminants

Yankee Coating and Release For Tissue production The coating sticks the sheet to the Yankee The release protects the Yankee from the continual pressure of the Creping Blade

Scale Control Geographically determined Chelant mixtures for simple systems Crystal modifiers for more complex systems and highly closed systems
Deinking Chemicals Recycled Printed Paper Products specially formulated for Washing systems and for Flotation Systems
Effluent Treatment All Paper Production (almost) Polymers for the removal of solids and color Odor removal chemicals
Process Water Clarification Recycled Paper Polymers and inorganic salts for SS removal so the water can be reused
