PF-115 (enamel) is a product for application on surfaces that have previously been coated with a primer. All kinds of materials can be used as a base, including steel, wood, etc.
Enamel features
The described enamel can be applied to surfaces that are used indoors or outdoors. PF-115 is a composition whose ingredients include fillers and dyes, as well as pentaphthalic varnish. Among other things, solvents and desiccants are added to the mixture during the production process. Enamel PF-115, the characteristics of which are described in the article, is often compared with water-based and oil compositions. The first version of the coloring agent has higher performance, has the ability to protect the surface, the properties of hardness and strength.
Enamel PF-115 gray, like similar compositions in other colors, has no worse characteristics compared to imported counterparts.
Specifications
If we consider PF-115 enamel, which is intendedfor application to metal, it is manufactured in accordance with GOST 6465-76. The viscosity of the composition is checked under conditions of 20 ± 0.5 ° C using a VZ-246 viscometer, the nozzle diameter of which is 4 mm. This indicator for enamel is equal to the limit of 60-120 s. Whereas the mass fraction of non-volatile substances can be 49-70%, which is affected by paint colors.
After application, the paint layer will shine in the range of 50-60%, this parameter is checked by a photoelectric gloss meter. PF-115 (enamel) after application will dry within a day, which is true if the external conditions remain within the temperature range of +20 ± 2 °C. Film adhesion index by points does not exceed 1.
The film after drying retains a certain stability, the surface strength will not be less than 40 cm. It is important to calculate the consumption of the composition before purchasing, it will be approximately equal to 150 g / m true on a perfectly flat surface. It is worth remembering that the figures mentioned are theoretical.
Applying technology
PF-115 (enamel) must be mixed well before application. Only the composition that has a uniform consistency should be used. If the paint is very viscous, then dilution can be made until the composition is suitable.
Apply by roller or brush. If there is a need to complete the work in a shorter time, then it is necessary to use an airbrush. The surface is preliminarily well cleaned, degreased and primed, whileprocess, you can use compositions such as AK, GF or EP. This applies to metal surfaces. Whereas in the case of a wooden base, it must first be scraped off, as well as grease stains and other contaminants should be removed from the surface.
PF-115 (enamel) is flammable, which is why the painted surface must be protected from direct exposure to fire. In the process of application, it is also necessary to comply with fire safety rules.
Good Features
Depending on what kind of surface you want to get, you should choose an enamel with a glossy or matte effect. White is used as the main color, but there are various shades on sale from which you can choose the one that suits you. The described enamel has the status of one of the leaders of Russian developments in the group of alkyd materials for coloring. It can be used in different climatic zones, as it has the ability to endure atmospheric influences such as solar radiation, snow, rain, wind and temperature variations. Thus, the coating on which the enamel was applied can be used in the range from -50 to +60 oС.
Enamel PF-115 after application forms a durable coating that is resistant to water, in addition, the surface after the paint has dried can be cleaned using detergents. The coating is not only high-quality and durable, but also looks great, looks uniform and does not have streaks. Paint can be tintedin all sorts of colors and shades. If you apply it in 2 layers on a surface that was previously primed and will be used in a temperate or cold climate, then the composition will not lose its protective ability for 4 years.
Features of using paint
Enamel PF-115 should be applied exclusively on a surface prepared in advance. It is recommended to apply the composition with a flat brush, which has a natural bristle. If parts are to be painted, then it is possible to facilitate the work and bring their completion closer by dipping the element; an alternative solution is pouring technology. If after opening the can there is a film on the surface, then it should not be mixed, it is recommended to get rid of it. Otherwise, application errors cannot be avoided. It is necessary to work at positive temperatures.
Enamel PF-115 (GOST 6465) should not be applied to a surface that has rust. If there are such errors, then they must be eliminated by using a rust converter, you can also resort to mechanical removal. If the base has cavities, then they must also be removed with alkyd putty.
There is another way to process a wooden surface. If it is not possible to use a sanding machine, the base can be sanded by hand, and then covered with drying oil. If there is old paint on the surface, it must be removed.
Applied to brick and concrete walls
EnamelPF-115, whose GOST is designated by the numbers 6465, can also be applied to walls made of bricks, as well as concrete. Previously, such surfaces should be primed and covered with putty. If there is old lime on the walls, then you need to get rid of it, rinse the surface with water, and then dry it.
Drying between coats must be done within 24 hours.
You should not dilute the paint with a solvent in large quantities, the volume of the latter should not be more than 10%. As a rule, white spirit is used for this. One kilogram of the composition will be enough to paint the base, the area of \u200b\u200bwhich is equal to the limit of 7-10 m22. The consumption of the mixture is approximately equal to 100-180 g/m2. If a colored pigment is used, then the consumption will be slightly higher.
Enamel reviews
Enamel PF-115, GOST which is designated as 6465, is often chosen by consumers. This can be judged by the numerous reviews. So, those who have already experienced the quality of enamel note that it shows the ability to perfectly protect surfaces. Among the responses of home craftsmen, one can often find satisfaction that enamel has an insignificant cost. Some developers emphasize that after applying paint to the surface, you can forget about the need for repairs for a long time.
