This diploma thesis is divided into two parts. In the first, literary one, a basic overview of materials, the reasons for use of surface treatment and its impact on the environment is mentioned. Also, the thesis contains a vast chapter on paints. In the second, exprimental part, the thesis deals with properties of three considered UV cured paints applied on two underlying materials, one of which was inert (plate glass) and the second one was a veneered component (chipboard, 8 mm thickness + venner of spruce, cherry tree and walnut tree). The paints mentioned were applied on the underlying material by glass rod and plastic spatula. Then they were cured within UV tunnel, manufactured by a company called FUSION. The curing took place under two different conditions, which had significant influence on the final properties - those conditions were different settings of transportation belt speed in the tunnel and different average intensity of the quicksilver lamps. Properties and endurance of these paints were verified by four selected tests. First of them verified hardness of the finished surface in accordance to methodology of determination of coat hardness by pendulum impact testing machine, which is based on standard ČSN 67 3076, the second test verified coats´ grinding ability using device Erichsen 255. Another test verified so-called chemical resistances of the finished surface according to standard ČSN EN 12 720: Assessment of surface resistance to cold liquids. Verifying of assessed paints´ mechanical endurance was integral to this thesis´ experimental part, where verifying of coat´s resistence to the abrasion in accordance to standard ČSN 91 0276 was chosen. Afterwards, on the basis of the knowledge gained from the experimental part of the diploma thesis a methodology for verifying of assessed properties of UV curable paints and its utilization in practice was suggested.
