Abstract
This research aim to analyze the effect of paint viscosity on the final coating's adhesion to the radial and tangential surfaces of Rajumas wood. The samples were sanded with abrasive papers and coated with water-based paint. The variations in Aqua Politur mixtures are based on percentages of 10%, 20%, and 30% from 1L of water. The viscosity of the Aqua Politur mixtures measured by the viscometer was 2.32 poise, 2.41 poise, and 2.44 poise, respectively. Paint adhesion testing uses the Cut Test method, which refers to ASTM D 3359-09. The results of the research show that variations in paint viscosity have a significant effect on the adhesion of the final coating material to the radial and tangential surfaces of Rajumas wood. A viscosity of 2.32 poise produces the best paint adhesion compared to a viscosity of 2.41 poise and 2.44 poise, and the difference in surface (radial and tangential) does not show a significant difference in the adhesion value of the final coating material to Rajumas wood.
