Composition and properties
This enamel is used for painting surfaces and products from a wide variety of metals: steel, aluminum, titanium, copper, magnesium, as well as their alloys. Before applying the enamel, the surface must be thoroughly primed.
EP-140 has a complex composition. It consists of two components, which are sold and used as a complete set. Usually it is a semi-finished enamel and hardener.
This composition withstands the peculiarities of the climate of the tundra and taiga, it is also adapted to the hot and dry conditions of the steppes, deserts and semi-deserts. However, enamel works best in a temperate climatic zone. Coatings treated with EP-140 enamel can be used both at home and at work. Enamel is used for both external and internal finishing works.
The coating is durable, it is distinguished by high hardness and excellent moisture resistance. The treated coating is unaffected by oil and gasoline.
We should also highlight the silvery enamel: the surfaces treated with it are capable of withstanding temperatures up to 200-250 degrees. Also, paint is released for processing rough metal without prior priming. Surfaces painted with such enamel are resistant to aggressive chemical environments.
All EP-140 enamels have a long service life. They can be applied in a variety of ways. They have a high drying rate, do not change their properties when hot dried.
GOST
GOST is a state standard that regulates the correct manufacture of products that meet all requirements, norms and technical characteristics. In 1976, GOST 6465-76 was created for PF-115 by the Ministry of the Chemical Industry, which sets out all the conditions for production, transportation, storage, guarantees, and quality.
There are other GOSTs, which mention the name of the enamel:
- 9980.1 - the rules of acceptance work are spelled out;
- 9980.2 - the procedure is spelled out in accordance with which samples are taken for analysis;
- 9980.3 - the rules for packaging, labeling are spelled out;
Purpose and areas of application
Due to its high viscosity and excellent adhesion, the use of PF 115 paint is very wide.
The composition can be painted:
- wood;
- concrete;
- plaster;
- putty;
- brick;
- metal.
It is not suitable except for roofing work - with strong heating of sheets of slate or tin, cracks may appear and the color changes greatly.
Enamel is used mainly for external work for structures in the open air. It is used both as a monolayer coating and as part of multilayer ones, in combination with primers, anticorrosive and antiseptic impregnations, insulating layers. Enamel does not possess its own antiseptic and bactericidal properties, therefore, when processing wood and walls made of brick or concrete in humid conditions, such additives are necessary.
Enamel PF-115 possesses and very high decorative properties - according to GOST 6465-76 it is produced in 22 colors and shades. In recent decades, manufacturers have offered modernized paint, which is available in almost all RAL colors. In this case, the color number from the catalog is indicated on the paint cans or barrels. This is one of the few cases when it is preferable to buy a paint made not according to GOST rather than a standard one. But it must be taken into account that this type of enamel costs more than usual due to the use of expensive dyes.
The high elasticity of the film, which can be obtained by painting surfaces in two or more layers (a single-layer coating is used only when renewing a previously completed finish with the same paint, provided that there are no cracks and blisters on it) allows PF 115 to be used in completely different climatic conditions.The temperature range at which the finished coating retains its properties is incredible - 50 ... + 60 C. But the paint fully complies with the declared characteristics only if all technological rules for applying the coating layer are observed. We will tell you how to use enamel correctly further.
What does marking PF-115 mean?
Well-known to professional builders and owners of private houses, PF-115 enamel appeared on the market in the distant 60s of the last century. Until now, it remains one of the most practical paints for various types of repair and construction work. Such durability of the paint is due not only to the low price, but also to a number of unique consumer qualities.
The paint is produced practically unchanged from the day it first entered the market. Its composition is regulated by GOST 6465-76. If you want to use the classic PF 115, then buy paint made in accordance with GOST. Many manufacturers make changes to the chemical composition and produce paint according to TU. It is very difficult to guess whether its properties are improved or worsened; it can only be verified experimentally. But there is not always time to do this, and not everyone can afford to buy paint, albeit inexpensive, for experiments.
The name of PF 115 encodes the chemical composition and the main areas of application. The index is understandable to a specialist, but does not mean anything to an ordinary buyer. However, the information is very important.
The letter PF symbol means that pentaphthalic varnish (a type of alkyd resin) acts as a binder for the paint. The scope of application of pentaphthalic paints is exterior and interior work on a wide range of materials.
Numbers 115 show the scope of application:
- 1 - for outdoor work in various climatic conditions;
- 15 - the number of the chemical composition, determined by GOST and deciphered by the manufacturer.
According to its physical state, paint PF-115 is a suspension, a suspension of solid and liquid particles of various kinds in a liquid medium. The particles are represented by solvents, dyes, pigments, desiccants, titanium dioxide and other fillers. The base is a rather viscous pentaphthalic varnish, which dissolves white spirit or other organic liquids.
Physical state and chemical composition
The paint itself is viscous, with small solid particles.
PF-115 enamel differs in color, brightness, tone and density, which is created by pigments (colored powders), which are responsible for the formation of shades and give transparency to some materials.
Pentaphthalic varnish is composed of vegetable oils, resin, rosin and glycerin.
In addition to pentaphthalic material, various oils and a desiccant are added to the solvent - a substance that helps to dry faster on the surface.
An organic solvent (white spirit) is added precisely to oil solutions.
The transparent substance is extracted from oil, it has an oily consistency, it liquefies the paint if it is too thick and does not affect the composition itself.
The paint contains titanium white (titanium dioxide), a non-toxic substance that creates a white pigment in paintwork materials, holds the oil on the surface and scatters light.
Alkyd enamel differs not only in a variety of colors, but also in moisture resistance, well tolerates prolonged exposure to UV radiation, and does not crack after drying due to its strength and elasticity.
PF-115 is already selling a certain color, but you can change it if you add another paint to the solution. At the same time, the volume will increase.
The most common shades:
- Blue.
- White.
- Gray.
- Beige.
- Pink.
- Orange.
- Cherry.
- Citric.
- Terracotta.
- Khaki.
- Red.
- Salad.
- Ivory.
- Black.
- Blue.
- Turquoise.
After staining, plastic, bendable structural parts retain their original appearance - the enamel does not break off and does not wear off with frequent interaction.
Chemical composition of PF-115 paint
In the classic form, the composition of the PF 115 paint includes various components, in depending on color... Different types of enamel differ, both in the number of components and in their percentage. But the peculiarity of this paint is that, regardless of the composition, the basic performance properties remain unchanged.
The paint is produced in ready-made colors; you can change the shade only by mixing different modifications of PF 115 in a certain proportion. Moreover, by mixing a precisely dosed test amount of different paints and having obtained the desired color, it is possible to proportionally increase the volume of components and prepare the required supply of paint of the desired selected shade.
For example, consider the composition of the most common types of PF 115 paint, the technical characteristics of which are largely the same.
White:
1.pentaphthalic varnish - 28%;
2. titanium dioxide - 62%;
3. white spirit - 10%.
Blue:
1. varnish - 26%;
2. TiO2 - 60%;
3. zinc white - 6%;
4. azure - 4%;
5. solvent - 4%.
Gray:
1. Varnish - 20%;
2. TiO2 - 75%;
3. carbon black - 0.5%;
4. solvent - 4.5%.
The paint produced in accordance with GOST exactly corresponds to this chemical composition and the coating will have the qualities that are indicated in the paint passport.
