| Summary: | The adhesion strength of coatings depends on various factors including wood type, the application
method of the coating on wood surface. The aim of this study is to determine the highest adhesion strength
from among eight varnish systems based on acrylic resin using varnish viscosity, film thickness and SEM
images. Oriental spruce (Picea orientalis L.) was used in the evaluation of the properties of adhesion
strength. Spruce wood surfaces were coated with varnish using a brush. Film thickness and viscosity values
demonstrated that varnishes with better penetration provided an improved adhesion, and better adhering
varnishes had an increased level of cohesive failure in the coating. Differences in the adhesion strength of
varnish systems were also observed on SEM images. |
