The effect of artificial aging on color, glossiness, pendulum hardness and adhesion to the surface of black poplar wood treated with UV curable varnish

Black poplar wood is used for the manufacture of furniture, paneling, and plywood. In this study, relationship between 3 5 layers UV system varnish applied to black (Populus nigra L.) artificial aging was investigated. addition, before after (252 504 hours), color parameters (∆E*, ∆L*, ∆a*, ∆b*, L*, a*, b*), glossiness, pendulum hardness, surface adhesion resistance (pull-off) tests were performed on varnished materials. According results obtained, both types, a decrease in L* value determined with increase time conditions UVB-313 lamps, while increases a* b* values. ∆E* values found be higher than that 3-layer application. it measurements made all directions degrees glossiness applications decreased increasing time. It observed hardness surfaces coats application coat application, decreases at end 252 hours an obtained hours. As result, recommended use material line usage areas according ambient desired (space floor preference).
