Sažetak

The aim of this study was to determine the effects of mechanical and ultrasound-assisted stirring methods for varnish + components mixing on the varnish layer coating adhesion, surface roughness and glossiness. For this purpose, polyurethane, acrylic and polyester varnish systems were applied on three different wood types, namely Scots pine (Pinus sylvestris L.), Eastern beech (Fagus orientalis L.) and Mahogany (Khaya ivorensis), with mechanical and ultrasound-assisted mixing methods. In the mechanical mixing method, 3 and 5 minutes were applied, while in the ultrasonic mixing method, beside 3- and 5- minute stirring time, 80-watt, and 120-watt ultrasonic power was applied during mixing. When research results are generally evaluated, it cannot be said that ultrasound-assisted mixing method is superior to mechanical mixing method. However, the ultrasound-assisted mixing of varnish components at 80 watts for 3 minutes can be recommended.
