Styrene-Butadiene Latex

Coating Performance

Rheological properties of the compound dictate how effectively a coater blade levels the slurry across a moving web. High shear stability ensures that the material does not coagulate or build up under the intense pressure of a blade coater or film press. Viscosity control remains a primary requirement for operators adjusting the coat weight to meet specific brightness or gloss targets on the finished sheet.

Uniform distribution prevents mottling or skip coating that would otherwise compromise the reproduction quality of offset or rotogravure inks.

Application Tolerance

Printability standards require a controlled ratio between the polymer and the mineral pigment to balance ink holdout against drying speed. Excessive amounts of binder reduce the porosity of the final sheet, potentially leading to smearing or picking during long production runs. Insufficient binder levels result in lower surface pick resistance, which causes fiber linting or pigment detachment when tacky inks pull away from the substrate at speed.

The correct formulation provides the necessary surface energy for uniform dot gain across the entire printed area. Consistent application of this synthetic binder reduces waste by maintaining stable pick strength throughout the duration of a production campaign.
