A Novel Silica-Based Nano Pigment As A Titanium Dioxide Replacement, Ryan Stoneburner
A Novel Silica-Based Nano Pigment As A Titanium Dioxide Replacement, Ryan Stoneburner
Masters Theses
This research focused on the evaluation of a new Silica-based pigment for the replacement of titanium dioxide (TiO2) in paperboard coatings. The silica-based pigment has shown the ability to be a replacement in terms of functionality and runnability. TiO2 is currently the highest opacifying pigment used in paper coatings, but it is also the most costly. Finding a less expensive pigment that doesn't reduce effectiveness is critical to reducing the cost of TiO2 formulations. To evaluate the new pigment, coatings will be applied using a Cylindrical Laboratory Coater (CLC) with varying amounts of TiO2 and …
