PF-115 (enamel): technical characteristics, GOST and reviews

PF-115 (enamel) is a surface application agent that has been primed with primer in advance. As a basis, all kinds of materials can be used, among them steel, wood and so on.

Features of enamel

The described enamel can be applied to surfaces that are operated inside or outside the premises. PF-115 is a composition, among the ingredients of which are fillers and dyes, as well as pentaphthalic varnish. Among other things, in the manufacturing process, solvents and desiccants are added to the mixture. Enamel PF-115, the characteristics of which are described in the article, is often compared with water-based and oily compositions. The first variant of the coloring agent has higher performance characteristics, 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 than imported analogues.

Specifications

If we consider the enamel PF-115, which is intended for application to metal, it is manufactured in accordance with GOST 6465-76. The viscosity of the composition is checked at 20 ± 0.5 ° C by means of a VZ-246 viscometer, whose nozzle diameter is 4 mm. This figure for enamel is the limit of 60-120 s. While the mass fraction of substances of non-volatile type can be equal to 49-70%, what affects the colors of the paint.

After applying the layer of paint will shine in the range of 50-60%, this parameter is checked by a photoelectric glossmeter. PF-115 (enamel) after application will dry during the day, which is true if the external conditions are kept within the temperature range of +20 ± 2 ° C. The index of adhesion of a film on points does not exceed 1.

The film after drying retains a certain stability, the strength of the surface will not be less than 40 cm. It is important to calculate the consumption of the composition before the purchase, it will be approximately equal to 150 g / m ² , which is true for a perfectly flat surface. It is worth remembering that these indicators are theoretical.

Application technology

PF-115 (enamel) must be mixed well before application. Use only the composition that has a uniform consistency. If the paint is very viscous, then dilution can be carried out until the composition is suitable.

Application should be carried out by means of a roller or brush. If there is a need to complete the work in a shorter time, then it is necessary to apply a spray gun. The surface is pre-cleaned well, degreased and ground, and the process can use compositions such as AK, GF or EP. This applies to the metal surface. Whereas in the case of a wooden base, it must first be uncracked, and also remove greasy stains and other contaminants from the surface.

PF-115 (enamel) is flammable, which is why the painted surface must be protected from direct fire. In the process of application, fire safety rules must also be observed .

Positive features

Depending on what surface you need to get, you should choose enamel with a glossy or matte effect. As the primary color is used white, but on sale there are different shades 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 staining. It can be used in different climatic zones, since it has the ability to withstand weather effects like solar radiation, snow, rain, wind and temperature variations. Thus, the coating on which the enamel has been applied can be used in the range from -50 to +60 ^о С.

Enamel PF-115 after application forms a strong coating that is resistant to water, in addition, the surface after drying the paint can be cleaned using detergents. The coating is not only quality and durable, but also looks great, looks homogeneous and has no streaks. The paint can be tinted in all kinds of colors and shades. If you apply it in 2 layers on a surface that was previously primed and will be operated in a temperate or cold climate, the composition will not lose its protective ability for 4 years.

Peculiarities of use

Enamel PF-115 should be applied only on a prepared surface in advance. It is recommended to apply the composition with a flat brush, which has natural pile. If you want to paint details, then to facilitate the work and bring them closer to completion, you can dip the element, as an alternative solution is the technology of watering. If after opening the jar on the surface there is a film, then it should not be stirred, it is recommended to get rid of it. Otherwise, the errors of application can not be avoided. Work is necessary at plus temperature.

Enamel PF-115 (GOST 6465) should not be applied to a surface that has rust. If such errors exist, then they must be disposed of using the rust converter, and mechanical removal can be resorted to. If the base has cavities, then they also need to be removed with alkyd putty.

There is another way of processing the wooden surface. If there is no possibility to use the sewing machine, the base can be sanded by hand, and then covered with linseed oil. If there is an old paint on the surface, it must be removed.

Application on brick and concrete walls

Enamel PF-115, the GOST of which is denoted by the numerals 6465, can be applied to walls of brick, as well as concrete. Preliminary, 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 layers should be done within 24 hours.

Do not dilute the paint with 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 color the base, the area of which is equal to the limit of 7-10 m ² . The consumption of the mixture is approximately equal to 100-180 g / m ² . If a color pigment is used, the flow rate will be somewhat greater.

Reviews about enamel

Enamel PF-115, GOST is designated as 6465, is often chosen by consumers. This can be seen from the numerous reviews. So, those who have already experienced the quality of enamel, note that it shows the ability to perfectly protect the surface. Among the responses of home masters, one can often find satisfaction with the fact that enamel has insignificant value. Some developers particularly point out that after applying paint to the surface, you can forget about the need to repair for a long time.
