ome have the impression that to run Pro-CoteŽ Soy Polymers, you have to reduce solids due to the product’s robust pigment interaction and fast immobilization. Even though this formulation approach represents technology available for certain applicator types, this contradicts the industry paradigm to run the highest solids possible to get the best properties.

Coating solids are raised as much as possible in paper and paperboard coating because of the resulting improvements in quality: higher solids result in better pigment holdout, more uniform coating structure, higher gloss and better smoothness.

Adequate dynamic water retention and colloidal stability are critical to formulate coatings to the highest solids, while allowing the system to run under the metering device.

Pro-CoteŽ provides this required water holding and colloidal stability. The introduction of a suitable soy polymer to high solids systems provides the opportunity to formulate for:

Higher average application solids, designing systems up to 70-71% solids.

Eliminating the coating dilution that occurs with most liquid or emulsion binders. Pro-Cote, supplied dry, can be dissolved directly in the pigment slurry.

Excellent water holding; coating does not dewater beyond its ultimate limit for stable running as solids are pushed near the maximum possible.

Cleaner blade runnability; less weeping, scratches.

Consistent coat weight profiles across machine.

And the well-known end product benefits of high solids blade coating.
