Abstract
The long-term durability of varnished wooden surfaces used in either indoors or outdoors environments depends on the resistance of varnish layers on these surfaces against potential physical, mechanical and chemical effects to which they may be exposed. In this study, "Nanolacke ultraviolet varnish", developed by a Turkish dying and varnish industry company and widely accepted as a 21(st) century technology has been compared to other conventional varnish systems widely used in the industry in terms of dry film resistance properties. In this study, cellulosic, polyurethane, polyester, synthetic and Nanolacke ultraviolet varnish have been applied on beech (Fagus orientalis L.) and oak (Quercus robur L.) wood samples which had been prepared according to the industry standards. Then, the hardness and adhesion resistance of these layers have been determined according to ASTM D 4366 and ASTM D 3359-2 standards, respectively.
Highlights
Wood is a natural continuously renewable material, which, nowadays there are many alternatives for it, over the centuries has never lost importance due to its superior properties
The aim of this study is to compare the hardness and adhesion resistance properties of newly developed nanolacke UV varnishes, which have been developed for wooden furniture and parquet surfaces, to conventional varnish systems
In Ozen and Sonmez’s study, the best result was obtained by polyester varnish, which was followed by polyurethane, cellulosic and synthetic varnish in terms of their surface hardness
Summary
Wood is a natural continuously renewable material, which, nowadays there are many alternatives for it, over the centuries has never lost importance due to its superior properties. Among the various surface processes applied to wood, varnishes are used to show its beauty, colour and the. 2008, 9 wood pattern resulting from its nature along a film layer. After the application of surface treatments performed according to industry standards the technical, aesthetical and economical value of wood increases. Varnishes and varnish systems used in wood surfaces have varied and developed over time, as a result of quality demands and environmental protection consciousness. The newest area of development in this field corresponds to the nanotechnology product varnishes discussed
