“…Changes in the chemical structure of acrylic coatings under the influence of battery acid (Points 3.2 and 3.4) contributed to their Buchholz hardness decrease. It was also found that the rate of hardness loss of acrylic coatings, aged climatically for 2 years, was higher than of unaged coatings, which resulted in the decrease of the aged coatings' resistance to scratching and erosion [23][24][25].…”

“…It is caused mainly by the fact that polymer coatings, which protect the surface of technical objects against the destructive influence of the environment (environmental factors), also submit to the destruction of complex aetiology [16,17]. It results from the simultaneous action of chemical substances (operational liquids, acid rains, and brine), mechanical loads (constant and variable stresses, erosive particles impacts), and aggressive products of the metabolism of microorganisms, as well as climatic factors like sunlight, wind, and rain or hail [18][19][20][21][22][23][24].…”

Renovation coatings of car bodies undergo destruction under the influence of operational factors. Like ultraviolet radiation, erosion, and aggressive media (among others, battery acid). This article concerns the evaluation of the influence of battery acid on the destruction of acrylic coatings previously non-aged, as well as aged climatically for 2 years. Ageing of the coatings with battery acid contributed to a degradation increase of their chemical structure. It was supported by a considerable increase in the polar component of surface free energy (SFE) of the coatings. In the case of prior climate ageing, the increase in the polar component was even higher. Moreover, the coating’s ability to absorb battery acid increased, which induced blistering. The DSC method revealed that the action of battery acid caused more intense oxidation of coating material, and as a result, the brittleness increased, leading to chipping of the coating surface layers. This led to the increase in surface roughness, measured using an interferometric method. The coatings previously climatically aged for 2 years presented higher values of surface roughness parameters than the non-aged ones. The increase in the surface roughness contributed to a substantial decrease in the gloss of coatings. A sharp difference in colour escalating with the lengthening of the ageing period was also observed using the spectrophotometric method.

“…The erosive wear process of polymer coatings is still not sufficiently recognized, because coating material loss depends on many interrelated factors (Asmatulu, Mahmud, Hille, & Misak, 2011;Kotnarowska, 1999bKotnarowska, , 2010bKotnarowska, Przerwa, & Wojtyniak, 2011). Therefore, studies on the erosive wear kinetics of polymer coatings should consider the degree of their destruction under the influence of such environmental factors like: acid rains, ultraviolet radiation, mechanical stresses (Barkoula, 2002;Patnaik, Satapathy, Chand, Barkoula, & Biswas, 2010;Kotnarowska, 1997Kotnarowska, , 2010a).…”

The paper presents results of investigation on the erosive wear kinetics of epoxy-polyurethane coatings modified with alumina or silica nanoparticles, aged climatically for three years. Destruction of coating surface layers due to natural weathering caused a decrease of their erosive wear resistance. Modification of the composition of polyurethane (surface) layer with nanofiller caused the remarkable increase of erosion resistance. Epoxy-polyurethane coatings with nanosilica modified surface layer, showed the highest erosive wear resistance of all investigated coatings.
