“…A gloss value more than 85 is considered high, values between 70 and 85 are standard, values from 40 to 70 are termed semi, and values from 15 to 40 are designated as low. 26 The adhesion properties of the different films without and with MWCNTs are listed in Table IV. The adhesion was found to be 100% for the films prepared without MWCNTs and with MWCNTs loaded at 0.5 and 1.0 wt %.…”

In this study, the contribution of multiwalled carbon nanotubes (MWCNTs) was studied for the evaluation of the performances of polyalkyd‐based films produced from dehydrated palm oil. Initially, different percentages of MWCNTs, including 0.5, 1.0, and 1.5 wt %, were considered for loading into the resin with the help of sonication. Additionally, a 1.0 wt % loading was considered for in situ conditions during the esterification process to achieve better dispersion and obtain improved properties of the film. The loading was evaluated by different performance tests, such as those of tensile, elongation, pencil hardness, swelling ratio, gel content, wettability, chemical resistivity, adhesion, and surface morphology. The results of mechanical testing showed that the addition of 1.0 wt % MWCNTs enhanced the tensile strength by 50%, whereas in situ conditions were found to be favorable for significantly improving the tensile strength by 75%. Moreover, the wettability, surface morphology, and thermal properties were also found to be in favor of in situ conditions for the dispersion of the MWCNTs. © 2015 Wiley Periodicals, Inc. J. Appl.

“…Despite their variety and comparatively low cost, ordinary organic paint coatings have one substantial defect, namely, short useful life, which requires construction materials to be often recoated; this, in its turn, causes large expenses due to the short overhaul life. However, the 60s of the previous century have brought a new type of paint coatings, that is, powder ones [5,6].…”

In the article the effect of fillers of various chemical nature on the corrosion resistance of polyester powder coatings in terms of flaking widths and corrosion expansion widths in accordance with DSTU ISO 4628-8: 2012 was reviewed. According to the results of studies, the effectiveness of the use of fillers to increase the corrosion resistance of the powder coating varies depending on the average particle size and crystalline form of the filler was found. As a rule, in order to receive a powder coating based decorative coating you should apply only one layer of paint, while liquid coatings require applying several layers; this increases the time of coating production. The powder coating can be easily utilized and recycled, thus the economic feasibility of production increases.

“…Powder coating is one of the most promising materials for creating technical and economic, and eco-friendly protective coating for a wide selection of building products and structures. Two groups of powder coating and lacquers are distinguished by their chemical composition: on the basis of thermoplastic film forming substances and on the basis of thermoset ones [10]. The coating on the basis of thermoplastic film forming substances is made without chemical transformations due to melting of powder particles with subsequent cooling of the hot melt.…”

Aspects for increasing the corrosion resistance of powder coating materials as a result of the involvement of the latest technologies for cleaning electroplating production waste are considered. The results of the effect of ferritization waste on the formation of corrosion resistance of coatings based on powder coating are shown. The introduction of the obtained ferritization waste into the composition of powder coating systems has a different effect on the formation of corrosion resistance of coatings was found. Thus, the control composition of the powder coating using a filler in the form of barium sulfate during 480 hours of exposure in the salt fog chamber is characterized by peeling of the coating at the level of 7.5 mm. The average width of metal corrosion is 5.5 mm. The category of corrosion resistance of the coating corresponds to class C3 (average) with the provision of an average durability class (M) from 7 to 15 years. Examples of typical environments (according to DSTU ISO 12944-2:2019) where the resulting coatings can be used are urban and industrial atmospheres, moderate sulfur dioxide pollution, coastal areas with low salinity. The use of galvanic waste sediments in general contributes to increasing the corrosion resistance of the powder coating. The efficiency of their use depends on the chemical composition of ferritization waste. Among the studied samples, the most effective is the introduction of waste in the form of Ni0.5Cu0.5Fe2O4 and Zn0.5Cu0.5Fe2O4 into the composition of powder systems, which helps to reduce the width of coating peeling by 65...79 %, as well as the width of metal corrosion by 75...80 % compared to the control composition. The least effective among the studied samples is the use of waste in the form of Ni0.5Zn0.5Al0.15Fe1.85O4 and CrFe2O4 due to a significant decrease in the corrosion resistance of the powder coating Powder coating systems were obtained using ferritization waste, the category of corrosion resistance of which corresponds to class C4 (high) with a high durability class (H) from 15 to 25 years. In general, the use of ferritization waste provides better corrosion resistance of coatings compared to traditional systems based on barium sulfate, which in turn gives reason to consider such systems as an alternative for corrosion protection of construction metal products and structures.
