Abstract
This is an investigation of the effect of paper-yellowing inhibitors on the viscosity-temperature dependence; scatter particle size, and the associated changes in the surface microstructure. The temperature has no effect on the qualitative viscosity behavior of the coating formulation including inhibitors. Particles size of pigment increases with the combination of UV absorber and radical scavenger. Transmission Electron Microscopy shows the microstructure of increasing agglomerations with added inhibitors to coating mixture. Numerical 3D simulation of the flow in the coating nip of metering size press taking inertia forces into consideration depicts vortex formations on the surface of the coater's rolls.
