“…A glassforming component, silica (SiO 2 ) or borate (B 2 O 3 ), is the major constituent of the frit, forming two distinct glass, silica-based and borate-based series. Other oxides are usually added, e.g., Na 2 O, K 2 O, and Li 2 Om, to control melting temperature of the frit (Rossi et al, 2021). Enamels are effective as high-temperature lubricants during hot forging.…”

“…Before the formulation of enamel, the frit must be suitably grounded in ball or drum mills. There are mainly two different types of milling: the dry and wet methods [34]. In the first case, the grinding takes place in the absence of water, and the charge is usually composed only of the frit, any pigments, and additives for special applications.…”

“…Enamels commonly show a high resistance to chemical agents, but their degree of resistance largely depends on the application purpose for which they are formulated. In general, it is possible to state that enamels are resistant to most solvents, acid, and neutral solutions, while they are easily attacked by solutions containing fluorides and strong alkaline boiling solutions (pH > 12) [34]. Their resistance to solvents makes them suitable to be used in environments where cleaning with aggressive detergents is carried out frequently, such as in road signs and architectural panels in stations and subways.…”

Porcelain enamel is an inorganic-type coating, which is applied to metals or glass for both decorative and functional purposes. This coating is a silica-based solidified glass mass obtained by high-temperature firing (temperature can range between 450 and 1200 °C depending on the substrate). Porcelain enamel coatings differ from ceramic coatings mainly by their glass structure and dilatation coefficient, and from organic paints mainly by the inorganic nature of the matrix and the chemical bond that exists between the coating and the substrate.

“…Many studies in literature regard the deposition of cataphoretic coatings on many different substrates, such as aluminum alloys 15–20 and Zn–Mn alloys, 21 with the application of different pretreatments 22 . Finally, reinforcing filler based on ceria‐titania nanoparticles 23 and functionalized graphene oxide flakes 24–27 have been added to cataphoretic baths to improve the protective properties of the polymeric matrix.…”

This study aims to assess the aesthetical performances of thermochromic coatings for outdoor applications. In details, this work focuses on the efficiency of thermochromic pigments inside cataphoretic and sprayed primers, evaluating the possible synergic effect of a protective transparent topcoat. The structure of thermochromic pigments is examined by optical microscope, and their color-changing behavior is evaluated by colourimetric measurements. Colourimetric analyses are also carried out to monitor the thermochromic performances of the coatings during exposure to an aggressive NaCl solution and UV-B radiations, and to assess the protective role of the topcoat. In addition to that, wet-and dry-abrasion tests are carried out to define the suitability of these coatings for outdoor applications where good resistance to mechanical damage is required. Thus, this work evidences the better aesthetical features of the cataphoretic primer, which, however, particularly suffers from chemicalphysical degradation processes. Nevertheless, the application of the transparent topcoat allows to maintain the integrity of the cataphoretic primer. The double-layer coating exhibits a remarkable color-changing behavior even when subjected to degradation phenomena due to exposure to aggressive environments.
