Drying oil "Oksol": features and specifications. Characteristics of drying oil Application of drying oil oxol

Today, drying oil is one of the main components of various putties and oil-based paints. And it is also very often used to process any wooden surfaces, for impregnating plastered work areas, and even for sealing small gaps. This versatile impregnation agent surprisingly combines many useful functions, which ensures its high demand.

Drying oil "Oksol" is especially popular, features and specifications which will be discussed below.

What it is?

Drying oil "Oksol" is a special impregnating mixture for the treatment of wooden and plastered surfaces before further painting. It protects wood and plaster from decay and bacterial damage. Can also be used for breeding oil paints. "Oksol" belongs to the category of semi-natural compounds.

More than 55% of the composition of the mass is vegetable oils, another 40% is a solvent, and the remaining 5% are desiccants, which contribute to the thickening and rapid absorption of drying oil into the tree.

The following can be used as solvents by the manufacturer:

• "White Spirit";
• synthetic analogues of vegetable oils;
• pyroplast or pyrolene;
• gum turpentine;
• nefras C4.

Dryers are auxiliary components that are responsible not only for the good absorption of drying oil, but also for its rapid hardening. Fused, oily or fatty acid resinants can be used as them.

The volume and type of solvents and desiccants used are regulated by special GOSTs developed for each type of additive separately.

Like other finishing and protective solutions, drying oil "Oksol" has its own unique technical parameters.

Specifications

Currently, the production of drying oil "Oksol" is regulated by such a document as GOST 190 78. This regulatory legal act regulates the composition of these products, the conditions and place of its use, as well as other parameters.

According to him, drying oil "Oksol" can be natural, belonging to category B. In this case, most of its composition is occupied by natural linseed or hemp oils. The main components of such solutions - vegetable oils - in Everyday life allowed to be eaten in pure form.

Combined "Oksol" belongs to the category of PV, most of its composition is corn or rapeseed oil. But the main difference is that they belong to semi-natural components, synthetic additives are included in them in advance, that is, such oils are technical and cannot be used for food.

In addition, the GOST states that this drying oil should have the following qualities:

• full transparency;
• pronounced smell;
• maximum drying time - 3 hours;
• acidity - 6-8 units;
• viscosity - 18-25 units;
• the flash point in a closed crucible is exactly 32 degrees.

"Oksol" of the PV group is suitable for indoor use only, and the product of category B can be used both indoors and outdoors.

The sale and transportation of drying oil can be carried out in containers made of special plastic or iron barrels made of acceptable metal alloys. If the product does not meet at least one technological condition, it should not be allowed for sale, as it does not meet the requirements of GOST.

Consumption

The consumption of this product is calculated based on the amount of substance spent per 1 m2 of surface.

The approximate cost is:

• drying oils of category B - 80-120 g / m2;
• "Oxoli" PV - 100-150 g / m2.

These consumption rates are approximate and may vary depending on the type of surface to be treated and the number of layers applied to it. For each subsequent layer, a smaller amount of composition is consumed.

It is also important to know that consumption will increase when impregnating plastered or too old wood structures. The consumption of drying oil "Oksol" is also affected by the method of its application - when using a brush, it is less than when using a roller.

Scope of application

Today drying oil "Oksol" is used in a number of cases:

• It can be used to paint wooden structures inside and outside facades.. In these cases, the solution prolongs the life of the wood, reduces the level of negative impact on it of temperature changes and pathogenic fungi.
• For processing plastered facades before their further painting. In this case, "Oksol" helps to reduce paint consumption during the final finishing, and also partially levels the work surface and protects it.
• For thinning oil-based paints. This allows you to increase the amount of paint, dilute the thickened substance without violating its technical qualities, and also use the resulting mixture as an impregnation and final solution at the same time.

It turns out that the use of drying oil "Oksol" is allowed for processing wooden structures indoors and outdoors, as well as for impregnation of plastered walls. At the same time, it is strictly forbidden to use this solution for painting and impregnating floors.

Manufacturers

Drying oil "Oksol" is in demand and popular finishing material, so today many brands are engaged in its production:

• The Tex company releases this product for sale in a completely ready-to-use form. Drying oil is sold in containers weighing from 0.4 to 8 kg in one container. The composition dries quickly, significantly reduces paint consumption and performs the work of a primer at the same time.
• OOO "Yamshchik" carries out the manufacture and direct sale of this impregnating composition, belonging to the category of PV. It is sold in containers with a capacity of 0.8 to 20 kg. This product fully complies with the requirements of SanPiN and is manufactured in strict accordance with GOST.
• Drying oil brand Isolate considered one of the highest quality. Manufactured in accordance with accepted standards. It is sold in containers with a capacity of 0.5 to 200 liters. The disadvantage of this company is that it produces drying oil of this type only to order and in bulk.

• VESTA-COLOR LLC manufactures and sells drying oil of this type wholesale and retail. The product of this brand is of high quality, affordable cost and high technical characteristics.
• PO "HIMTEK" for over 20 years engaged in the manufacture and sale of these products highest quality. Drying oil "Oksol" of its production always has excellent technical characteristics and affordable price. Sold in containers different kind, which allows each buyer to purchase the most suitable packaging.

Drying oil "Oksol" produced by all these brands in practice has proved its high efficiency and excellent quality, therefore, when purchasing such a product, it is recommended that you first of all pay attention to these manufacturers.

Features and rules of application

This composition belongs to the category of quick-drying and quick-hardening substances, therefore, it requires compliance with certain recommendations when working with it:

• the mixture is sold in a ready-to-use form, but before using it directly, it is recommended to thoroughly mix the drying oil so that the active ingredients are evenly distributed throughout the liquid;
• impregnation can only be carried out on dry, clean and previously degreased surfaces;
• it is necessary to apply the solution in a rather thin layer, using a wide brush or a small roller for this;
• air temperature during work should not be below 15 and above 20 degrees, and humidity - no more than 75%;
• each layer of drying oil dries for about a day, so each new application should be carried out no later than 24 hours later;
• it is very important at the end of the work to remove from the room all the tools and materials that have come into contact with drying oil;

• unused mixture can be stored for no more than 12 months in a hermetically sealed container;
• during work it is recommended to use a respirator or a protective mask and rubber gloves;
• if the composition has got on the skin or in the eyes, it must be thoroughly washed off big amount water;
• when working indoors, be sure to provide access to fresh air;
• drying oil "Oksol" is highly flammable, so it should be used as far as possible from open sources of fire;
• upon acquisition this tool be sure to require the seller to provide certificates of quality, safety and compliance with the requirements of GOST;
• this composition is also allowed to be used for sealing small cracks. For this drying oil is mixed with sawdust in equal proportions and applied to the surface to be treated with a spatula.

During some construction and repair work often used material such as wood. The tree has a porous structure and therefore more than others needs additional processing.

In order to protect this valuable and not entirely cheap material, Oksol drying oil is used.

What it is?

Drying oil is a thick oily liquid mainly Brown, consisting of a mixture of different components, is intended for painting wood and preparing plastered surfaces for painting, and is also used as a solvent for oil paints.

Like any other product intended for processing, drying oil consists of basic and auxiliary substances. The basis of drying oil "Oksol" is vegetable oil, the share of which is in the range of 54-55% of the total mass.

Different oils can be used to make the product: linseed, hemp, sunflower, grape, soybean, corn or camelina. The base contains either one type or a mixture of several oils.

The share of additional components in the composition of "Oxol" accounts for 45% of the total mass, of which 40% is occupied by a solvent (white spirit is most often used), and the remaining 5% are desiccants. Each of them has certain properties that affect the composition as a whole.

The solvent gives the drying oil the desired consistency, and the desiccants contribute to the rapid drying of the composition on the surface. Salts of various metals, and, more precisely, compounds of iron, cobalt, lead, lithium, strontium and many others with organic acids are called driers.

The film formed on the surface does not allow paint or varnish to penetrate deep into the wood structure, which means that less material is required. In addition, the use of drying oil as a preparatory layer for painting improves the adhesion of varnish or paint to a wood surface.

In order to understand how and due to what the film is formed on the surface, it is necessary to consider the principle of drying oil, based on the properties of the components. Many types of vegetable oils used as a base, under certain conditions (oxygen, heat, light) are able to thicken, and when applied to the surface in a thin layer, polymerize (dry).

The formation of a semi-solid mass occurs due to polyunsaturated fatty acids present in some oils of vegetable origin. The rate of solidification on the surface is directly dependent on the value of glycerides of unsaturated fatty acids and such an indicator as the iodine number. The higher the percentage of fatty acids in the oil and the higher the iodine number, the faster the polymerization process.

But the natural oxidation process is slow, and therefore the drying oil is subjected to heat treatment along with driers added to its composition. Heating of this composition leads to the decomposition of substances that slow down the formation of the film, and due to the presence of metal salts, the oxidation process is faster.

Desiccants affect the composition not only during the drying process, but also after it. It lasts all the time the layer remains on the surface, their proportion should not exceed 5%, a higher percentage of their content in the composition leads to darkening, and then the destruction of the film coating.

The formation of an elastic film on the surface usually occurs within 6-36 hours. Such a run-up in time is due to many factors: composition, preparation technology, the presence of additives. Almost all drying oils known today dry for about a day..

Kinds

To date, manufacturers produce several varieties of oil-based drying oils, differing in the presence of additional components and the percentage of basic substances.

Natural drying oil is the basic basis for "Oxoli", but differs from it in the percentage of components and the absence of additional substances in the composition. The share of oil, most often linseed or hemp, accounts for 97%, and the remaining 3% are desiccants.

This type of drying oil is suitable for processing surfaces that are only indoors., in connection with which it is used infrequently, and the cost of this type is quite high due to the large percentage of oil in the composition and its initial price.

Drying oil "Oksol" it is much cheaper than natural, because the share of oil in its composition is only 55%. But the reduced proportion of oil and the solvent included in the composition do not this species drying oils are worse than natural. It is in no way inferior in properties and appearance natural analogue and even surpasses it in some ways.

"Oksol" can be used to cover wooden structures and plastered surfaces not only indoors, but also outside, which is its undoubted advantage.

On the treated surface a stable coating with a gloss effect is formed no later than a day. It is characterized by elasticity, water resistance and maximum durability compared to other types. The only disadvantage of Oxol is its harsh smell compared to its natural counterpart due to the presence of a solvent, which is most often white spirit.

The division of "Oxoli" into brands is due to the use of different oils that make up the basis. For brand "B" either hemp or linseed oil. The best drying oil is considered to be made on the basis of linseed oil., it is it that forms a more durable coating on the surface.

The composition of the brand "PV" is based on other types of oils (soybean, sunflower, camelina, grape, corn).

A surface treated with a sunflower oil based composition is less resistant to various influences compared to a linseed oil base.

Combined drying oil unlike other types, it contains several types of oils that undergo various processing. In particular, if cheaper and poorly drying rapeseed oil is added to the composition, then it is preliminarily subjected to oxidation. This process is necessary in order for drying oil with cheaper oils used as a base to approach the original version in terms of properties.

The composition of the combined drying oil also includes synthetic substances and a solvent. Such drying oil is marked with the letter "K", and the number following the letter indicates for what types of work the composition can be used. Even numbers indicate drying oils intended for surface treatment indoors, and odd numbers mark compounds that can be worked with outside.

Alkyd drying oil has some similarities with Oksol. Vegetable oils are present in the composition of alkyd species, but their share is insignificant. This type of drying oil is produced on the basis of alkyd resins, which are diluted with solvents, most often with white spirit. In addition, the composition includes desiccants.

Specifications

Drying oil "Oksol" is produced in accordance with GOST 190-78, which prescribes the norms of various indicators for grades "V" and "PV". There are eight basic standards by which drying oil is determined to belong to one or another species.

They vary depending on the type of oil used and the brand of drying oil itself:

• The color index is listed first in the table.. For both grades, this value is identical, the color should not be darker than 800 mg J / cm³ (according to the iodometric scale). But there are exceptions for drying oil, where camelina oil (PV brand) acts as the basis, this indicator has a different numerical expression. The color of such drying oil should not be darker than 1800, and for drying oil made on the basis of soybean oil, this figure is 1100 J / cm³.

• Conditional viscosity indicators, measured with a viscometer, differ slightly for the two grades. For brand “B”, the drying oil flow time through a funnel with a diameter of 4 mm (at t = 20 ° C) is within 18-22 seconds, and for brand “PV” - within 19-25 seconds.

• Acid number, measured in mg KOH/g, for different brands is different. For brand "V" this indicator should be no more than 6, and for brand "PV" it is slightly higher - 8. If sunflower oil, whose acid number ranges from 8-15 mg KOH / g, the total acid number should not exceed 10.

• Mass fraction of non-volatile substances, measured in%, for both brands should be in the range of 54.5-55.5. If there is a petroleum polymer resin in the drying oil mixture, the mass fraction of non-volatile substances can vary between 55-59%, provided that the viscosity index corresponds to the standards specified by GOST.

• Indicators such as sludge by volume and transparency both brands have the same size. Sediment by volume - 1%, transparency - full. The flash point in a closed cup for both grades should not exceed 32 ° C.

• There is another important indicator characterizing drying oil by drying time. For brand "B" a stable coating (up to degree 3) is formed no later than 20 hours from the moment of application, and for brand "PV" - no later than 24 hours.

According to GOST 190-78, there are strict requirements prescribing which containers can be filled with drying oil, at what temperature the liquid can be safely stored, and what precautions to take when opening a can with a composition. All safety requirements are described in detail in this document.

When buying drying oil, sellers must have a quality certificate.

Consumption per 1m²

There are norms for the consumption of drying oil per 1 m². As a rule, these indicators are not very different from the consumption of oil paints. To apply drying oil in one layer per 1 m², it will take from 80 to 130 g. This run-up is due to factors such as the type of surface to be treated (wood or plaster), the porosity and hardness of the material, the type of mortar, as well as the effect of temperature and humidity.

For fresh wood, the consumption can be increased up to 200, and in some cases up to 250 g per 1 m². According to some sources, the average consumption of drying oil for a single-layer coating ranges from 150-200 g per 1 m².

Any kind of work on interior decoration rooms that are associated with painting wooden surfaces with oil paints cannot do without the use of drying oil. Even despite the recent emergence of new, more advanced formulations that perform the same tasks. What is drying oil? Why is it needed and how to use it correctly? - these are the questions, the answers to which will help to get a perfectly painted surface.

Drying oil types

At the moment, it is customary for experts to distinguish three types of drying oil: natural drying oil, drying oil "Oksol" and composite drying oil.

natural drying oil

Natural drying oil, the quality of which is strictly regulated by GOST 7931-76, consists of 97% of vegetable oil natural origin (linen or sunflower), which has undergone a special heat treatment, and 3% from a desiccant.

1. Such drying oil reliably protects wood, however, it can only be used indoors.
2. In addition, natural drying oil has enough high cost by today's standards.

Drying oil "Oksol"

Drying oil "Oksol", the qualitative composition of which must comply with GOST 190-78, is a substance that has a slight odor and consists of 55% vegetable oil (linseed or sunflower), 49% white spirit and 5% desiccant.

1. "Oksol", on a par with natural drying oil, perfectly copes with its main task, namely, it protects wooden surfaces, forming a dense film that is resistant to water, which does not blacken for a long time.
2. At the same time, drying oil "Oksol" is much cheaper natural drying oil and it, unlike the latter, can even be used to treat any surface outside the building.
3. The best is the Oksol drying oil, which has linseed oil in its composition, so it costs a little more than the one made on the basis of sunflower oil.

Composite drying oil

Composite drying oil is the cheapest drying oil with a characteristic pungent odor. It does not have a GOST number, so the composition of such a substance is not regulated at the legislative level, and production is carried out exclusively according to technical specifications.

1. Composite drying oils, as a rule, contain various chemical components, in particular, products of the petrochemical industry that are harmful and toxic to the human body (for example, petroleum polymer resins).
2. Therefore, such compositions are strictly prohibited for indoor use.
3. The smell of composite drying oil remains for a long time even with good ventilation in the room. this is the cheapest drying oil with a characteristic pungent odor.

Features of the use of drying oil "Oksol"

Drying oil "Oksol" is a quick-drying substance that has an increased hardness and forms a glossy coating on the surface of the material processed by it. It penetrates well into the pores of the tree, thereby emphasizing its structure.

• Drying oil "Oksol" is for sale in containers of various capacities, completely ready for use.
• It is necessary to apply such a substance on a dry surface, which, if necessary, is sanded in advance and thoroughly cleaned of dust or grease. Only after that do they move on to polishing.
• First, the composition is well mixed, if the drying oil has thickened during storage, it can be diluted with white spirit, nefras, and also, if desired, a solvent for varnishes and paints (oil and enamels).
• The drying oil is applied in a thin layer with a brush or a special roller. At the same time, all work must be carried out in a room that is well ventilated with an air temperature of at least 15 degrees Celsius and a relative humidity of 80%.

• The drying time of drying oil "Oksol" is approximately 24 hours, so the interval between each subsequent layer should be approximately a day.
• The rest of the unused drying oil can be stored for a year in a tightly closed container. For this, a dark, dry place inaccessible to children is suitable.
• To protect your hands during the polishing process, it is recommended to use rubber gloves. It is also important to avoid getting drying oil in the eyes. If drying oil has got on open areas of the body, then they are cleaned with rags or a rag soaked in vegetable oil. Then thoroughly wash everything with warm soapy water.
• With the help of drying oil "Oksol" it is also possible to putty small cracks by mixing it with sawdust until a thick homogeneous mixture is obtained.
• All work to avoid fire hazards must be carried out away from sources of open flame.
