Coating Additives Technology

Solenis' family of coating additives enable paper and paperboard manufacturers to optimize their coating process performance or implement new surface performance applications. In particular, coatings colors that are subject to high-shear conditions during high-speed coating processes must remain a stable dispersion with good water retention. We have deep expertise in tuning coating colors for specific paper and paperboard production processes, enabling mills to increase productivity without compromising quality.

Product Range

Our portfolio of coating additives are water retention and rheology agents that can be adapted to your coating application and can be optimized to meet any specific requirement to improve your production process:

Our flagship product, TopBrane™ coating additive is a hybrid biopolymer that enhances dispersion effects even on highly pigmented coating colors. TopBrane™ enables papermakers to maintain lower viscosity at higher coating color solids and can be used in film press or blade applications.

PreTop™ coating additives provide a range of chemistries to help papermakers meet specific needs. PreTop™ acts as a rheology agent that uses co-binding and dispersion properties to improve water retention and regulate rheology.

TopSol™ coating additives encompass a range of polyvinyl alcohol (PVOH) solutions that act as co-binders and extenders for optical brighteners.

Recorded Results

Solenis' coating additives are used in topcoat applications to modify the characteristics of the coating color to improve surface performance and runnability. Papermakers using our products have reported that they have been able to successfully optimize a number of parameters, including:

  • Water retention
  • High shear behavior
  • Coat weight control
  • Dispersion degree
  • Interaction coating with substrate
  • Printability
  • Digital printability
  • Ink and coating hold out
  • Extender effects
  • Sealability
