Air knife coatings run in the 40-50% solids range because coat weight cannot be controlled as solids levels increase above ~55%. The nature of this design creates potential for non-uniformity during the consolidation and drying process.

Demands are placed on the coating formulator to design systems that maintain maximum uniformity and coverage, yet work within the parameters of the air knife. Formulating with Pro-Cote® Soy Polymers can impart the following properties versus other alternatives:

Good coating uniformity through coating bulk,

Equal coverage/appearance values at 10-50% lower coat weights

Pigment package efficiencies (removing/reducing use of opacifying pigments), and

Potential to reduce quality of topliner furnishes with equal visual appearance.
