Formation of coatings (PC) – is the curing (drying) coatings (paints), which takes place in specific time-temperature conditions, which is one of the most important stages of technological the process of staining, a significant impact on physical and mechanical, safety, and in some cases, decorative properties of PS. The technology of coatings distinguish natural and artificial drying. Natural drying carried out under normal conditions (for example – drying enamel PF-115), energy-intensive artificial drying, process is implemented using a special, sometimes technically complex equipment. So natural drying paint is always preferable, and in many cases due to the specific technology, the only possible. This is particularly relevant curing method for coloring large products on open sites, in rooms with PC repair.

To cure the in vivo requires a certain, for most paints an extended period of time. Therefore, methods for accelerating curing of in vivo is of considerable practical interest. They are based on the use of quick-drying paint consisting of film formers, such as acrylic or perchlorovinyl. To reduce drying time results in chemical or physical modification of epoxy, alkyd and urethane oligomers cured under natural conditions in a long time. For example, the combination of epoxy resin oligomer perchlorvinyl cuts drying time of epoxy coatings with 24 to 1 h at 20 C, akriluretanovye materials cured under normal conditions for 2 – 4 pm Currently, various manufacturers developed a number of coatings, fast drying in natural conditions. This – epoxy-vinyl enamel EP-1294 EP-1267 EP-1236, "Evikor"; akriluretanovye enamel AU-1518 "Universal Luxury" AK-1511 "Raznotsvet" as well as widely known glyptal materials – primer GF -021, and others. And is characterized accelerated drying time under natural conditions, these coatings can be applied not only to paint outdoors or in repair technology, but also on the production of conveyor lines. Using the dilution of the material more volatile solvents, reducing the thickness of layer applied, the number of layers, the use of catalysts, cure, more active hardeners and accelerators are also resulting in intensify the process of curing the PC in the wild.
