Henke, Milena Rheological study of industrial varnishes at various temperatures / Milena Henke, Tomasz Krystofiak, Barbara Lis. -- Obr., tab. -- Lit. - Superior surface finishing in furniture manufacturing requires an understanding of varnish product rheology. The rheological properties of acrylic primer, basecoat and topcoat, in- tended for roller varnishing and UV curing are examined in the study. Two methods were used to measure viscosity: Brookfield rheoviscometer and Ford cup. The results discuss the effect of increasing temperature on a decrease in viscosity. Rheological modeling using the Ostwald de Waele power law model explained the non-Newtonian, shear-thinning, rheosta- ble behavior of liquid. It was shown that the flow index of some varnish products in Standard Conditions for Temperature was close to the Newtonian fluid. However increasing con- sistency index parameter indicates the pseudoplastic behavior of the fluid. The findings high- light the importance of controlling viscosity and temperature during varnish product appli- cation processes to ensure optimal coating quality. This research provides valuable insight into the rheological properties of industrial coatings, facilitating advances in coating tech- nology and quality control practices.
