“…A study of the stability of nanocomposites samples and their components in alkaline media showed that SiO2-TiO2, TiO2-ZrO2, and SiO2-ZrO2 nanocomposites samples in alkaline media are subject to dissolution, and SiO2-TiO2-ZrO2 nanocomposite samples do not Following data analysis, it was found that the developed nanoscale composite protective coating is able to maintain its hydrophobic properties (θ ≥ 90 • ) for more than 150 wash cycles. This indicates that the developed preparation has high potential for industrial use as protective composite coatings [43].…”

“…For the experiment, 10 cm × 10 cm metal plates were prepared, on which a paint and varnish coating was applied using all the necessary technological operations, obtaining an experimental surface that completely imitates the paint of a car [43]. The preparation for the formation of a nanoscale composite protective coating was applied to the surface of the plates according to Section 2.6 and examined by diffuse light reflection and scanning electron microscopy (SEM).…”

In this work we have developed a nanoscale composite protective preparation for car paint and varnish coatings. We developed methods to obtain SiO2-TiO2, TiO2-ZrO2, SiO2-ZrO2 and SiO2-TiO2-ZrO2 nanocomposites, which are crystallization centers for the formation of a nanoscale composite protective coating with certain morphology and roughness. The phase composition of the samples and stability in alkaline media were studied. It is shown that SiO2-TiO2-ZrO2 nanocomposites with a content of titanium dioxide from 8%–9.5% and zirconium dioxide from 0.5%–2% exhibit complete insolubility in a highly alkaline medium, allow to form uniform structure on paint and varnish coatings, and protect the car surface from exposure to ultraviolet radiation. We determined the optimal composition of the preparation components for the formation of a nanoscale composite protective coating with hydrophobic properties and a wetting contact angle of more than 120 degrees: tetraethoxysilane ≤ 10 vol.%., titanium tetraisopropylate ≥ 2 vol.% and plant resin ≥ 8 vol.% Practical approval of the developed preparation on BMW X6 showed a pronounced hydrophobic effect. Evaluation of the stability of the nanoscale composite protective coating to the washing process showed that the developed preparation is able to maintain its hydrophobic properties for more than 150 washing cycles.

“…Coating defects are a common result of various factors that affect the quality of painting (Haryanto and Ichtiarto, 2019). These factors include humidity levels in the room, temperature during drying, excessive layers of paint and varnish, nozzle application distance, nozzle air pressure, and others (Khasanov, Rassokha and Kabanova, 2019).…”

Environmental influences can cause corrosion or damage to materials, which is why paint coating is used to protect them. Some of the factors that affect the quality of the paint are technical, such as setting the air pressure and spray gun nozzle spacing. The experimental research aims to determine how air pressures of 1.5, 2, and 2.5 bar and nozzle spacings of 10–15–20 cm affect the gloss and thickness of the water-based paint layer. A gravity-feed spray gun was used for this purpose. The luster test method uses an AMTAST AMN60 glossmeter with the ASTM D523-08 standard, and the thickness test uses a coating thickness gauge with the ASTM E 376-96 standard. The air pressure and the distance of the spray gun nozzle affect the gloss and thickness of the paint layer. Parameter 2 bar/15 cm yielded the highest gloss of 92.77 GU, while parameter 2.5 bar/10 cm resulted in the highest coating thickness of 0.26 mm.

“…Khasanov et al [34] presented main factors influencing the quality of paint and varnish coating when repairing the car body. The main important factors from point of view of the quality of renovation coating were i.e., pollution of compressed air and varnishes, paints and varnishes application on badly prepared surface as well as the use of inappropriate paints and varnishes or the solvent.…”

Assessment of Selected Properties of Varnish Coating of Motor Vehicles

The technology and methods of testing the properties of varnish coatings used in motor vehicles are constantly and successfully developed. However, in the case of automotive varnish renovation coatings used in the repair of car bodies, the problem of fitting the quality of these coatings to the quality and current condition of the coating applied to undamaged vehicle components is not definitely solved. The main goal of the research was to determine the thickness and gloss distribution of the varnish coatings. The thickness and gloss of the varnish coating on the entire body of the vehicle were measured. Classical methods of assessing these properties were used. Defects in the renovation coating were also simulated, to show their negative impact on the varnish quality. The performed tests allowed for development of a procedure and algorithm for evaluation of the quality of the car’s renovation coating after the repair of the car body. The proposed procedure, expressed with the presented algorithm, allows to fit the obtained renovation coating to the quality and condition of the coating manufactured in factory on the car body in the range of its thickness up to 270 µm and gloss in the range of 5–90 GU. The developed procedure for the assessment of renovation coatings can be used in workshops that repair vehicle bodies. This will allow to improve the quality of renovation coatings and bring their properties, such as thickness or gloss, closer to those applied to the vehicle’s body at the factory.
