Özet

In this study, it was aimed to determine the abrasion resistance and scratch resistance of water-based, polyurethane, and acrylic varnish applied to naturally aged and fresh scotch pine (Pinus sylvestris L.), sessile oak (Quercus petrea L.) and chestnut (Castanea sativa M.) wood surfaces. The test samples prepared for the experimental study were sanded with 150-grit sandpaper after they were kept in conditions of 20±2 oC and 65±5% relative humidity until the equilibrium humidity was reached. The varnish was applied to the surface of the test samples with a paint spray gun perpendicular to the grains and then parallel to the grains. Abrasion resistance was determined in accordance with TS EN 15185 and scratch resistance was determined in accordance with TS EN 15185 principles. As a result, it was determined that the wood type, age period (naturally aged and fresh), and section direction were not effective on abrasion and scratch resistance, whereas the varnish type was effective.
