Forecasting of durability of waterborne coatings in the machine industry

Lenik K., Gauda K., Lenik Z.

Archives of Materials Science and Engineering

2009

Vol. 37, nr 2

102-109

Purpose: The paper presents the problems of forecasting of durability of waterborne acrylic coatings and epoxy coatings designed to protect devices and machine elements. Design/methodology/approach: The durability forecast has been performed on the basis of analyses of time series with the use of trend function extrapolation. Mechanical properties such as: scratch resistance, impact strength, grindability and luster have also been evaluated. Moreover, besides standardized methods, some complementary methods have been applied in the form of analyses of microscopic images of damage caused by the exposition of coatings to corrosion. Findings: Assuming five-year durability for coatings on devices and machine elements (time between overhauls), one can find that investigated waterborne coatings can be a successful protection of devices and machine elements in the established range and in the dependence on the applied system. Research limitations/implications: The research has shown some substantial influence of coating system width changes on obtained results of scratch resistance and impact strength. It should be beneficial to extend further research with the description of the mechanism that enables to obtain some strict correlation between the investigated properties of coatings and the allowance of their width. Practical implications: The research makes possible to determine the areas of application for coatings obtained from waterborne materials to anticorrosion protection of devices and machine elements. This enables to eliminate gradually traditional solvent coatings (of high VOC content), which are disadvantageous to the environment. Originality/value: The applied sequence of research can form a proposal of the method to evaluate coatings made of some other than investigated waterborne materials predestinated for machine industry.

Polski przemysł farb i lakierów w ostatnich latach charakteryzuje się wysoką dynamiką wzrostu produkcji. Dotyczy to szczególnie ekologicznych wyrobów wodorozcieńczalnych i farb proszkowych. Szybko rośnie eksport wyrobów lakierowych, zwłaszcza na rynki Europy Wschodniej. W Polsce istnieje około 500 producentów wyrobów lakierowych, w tym 6 wielkich i około 25 średnich. W artykule przedstawiono również rynek wyrobów lakierowych. Około 70% całkowitego zużycia wyrobów lakierowych w Polsce stanowią wyroby dekoracyjne. Prawie 75% tych wyrobów wytwarzanych jest przez 5 dużych producentów: SigmaKalon Deco Polska Wrocław, Śnieżka Lubzina, Tikkurila Polska Dębica, AkzoNobel Coatings Włocławek oraz ICI Polska Pilawa. Wysoką dynamikę wykazuje również rynek farb przemysłowych, których największym producentem jest SigmaKalon Cieszyn.

Polish paint industry has shown a high dynamic of production growth for several years now. In particular with regard to ecological waterborne and powder coatings. Export to the markets of Eastern Europe also registers fast growth. More then 500 paint manufacturers operate in Poland, among them 6 large manufacturers and some 25 medium-size ones. The structure of the paint market is also presented in the article. In the polish paint market decorative coatings count for nearly 70% of all paints consumed. Almost 75% of decorative coatings is produced by 5 large manufacturers: SigmaKalon Deco Polska Wrocław, Śnieżka Lubzina, Tikkurila Polska Dębica, AkzoNobel Coatings Włocławek and ICI Polska Pilawa. Market of industrial coatings also shows high dynamics, the most important manufacturers in this market is SigmaKalon Cieszyn.
