Drying oil is a liquid substance taken by a film made using vegetable oils that have undergone special heat and chemical treatment, or alkyd resins. Use it in the production of oil paints, putties, paints, primers. It is used for impregnation and coating of wood, in order to protect products from rotting, wood parasites and moisture. If you have a thick varnish available, than to dilute it, you will soon find out.
Classification of drying oils
Depending on the composition and processing method, drying oil is classified into the following types:
- natural drying oil;
- drying oil oxol (semi-natural);
- combined.
In the modern world, natural and semi-natural are popular, combined is less in demand. Each of the types of oil drying oil is predisposed to solidification, subsequently there is a need to dilute. How to dilute drying oil on your own, without resorting to anyone else's help, can be found in this article by studying what components are included in its composition.
Natural drying oil
The composition of natural drying oil includes vegetable oils with the addition of substances that contribute to the acceleration of its drying. In turn, drying oil, depending on the oils present in its composition, is divided into hemp, castor, tung, linseed and sunflower.
Natural drying oil has the properties of a solvent for paints and varnishes. The need for dilution of such a composition arises very rarely, since the oil can be in a liquid state for a very long time and not require the addition of a solvent.
The first subspecies, linseed oil containing hemp oils, has a darkish tint; hemp oil and a solvent are used for its manufacture. Got its application in the construction industry: they are used for coating wood and metal products, plastered surfaces, as well as in the preparation of putty mixtures and oil paints.
Flaxseed linseed oil is based on linseed oil using a solvent that is also made from flaxseed oils. Has a transparent shade. Used for priming various types of surfaces. Drying takes place during the day.
Sunflower linseed oil is elastic, but along with this quality there is another thing - hardness, strength and water resistance suffer, which can not be said about hemp and linseed oil. The drying period is much longer.
Than to dilute drying oil based on natural oils
It should not be forgotten that natural drying oil refers to substances of increased fire hazard, if the rules and safety precautions are not observed, it can easily ignite. It is necessary to understand how to dilute natural drying oil in everyday conditions. If you decide to resort to this, then you need to follow a number of rules: carry out the work process in a room with a functioning ventilation system, away from the sources of ignition and only proven fluids to dissolve thickened drying oil.
Castor oil, white spirit solvent, various organic acids, turpentine or solvents for oil-based paints are used to dilute drying oils of this composition. The dilution process is simple: you need to take a little oil drying oil and dilute it, observing the resulting reaction.
Drying oil
The composition of semi-natural drying oil (oxol) includes natural vegetable oils and solvents that have undergone prolonged heat treatment. Solvents predominate in its composition, due to which the product has an unpleasant specific odor, which sometimes persists even after drying on the treated surface. The color of drying oil of the available composition is light brown or brown. It has the ability to dry quickly. The main task of drying oil of this type is to protect wooden surfaces from parasites and moisture, after covering it with products, a protective film is formed. It also gained distribution in the paint and varnish industry; it is used in the manufacture of paints and for their dilution in the process of performing internal and external painting works. The surfaces of products primed with such drying oil acquire a high gloss, high strength, and become waterproof. At the cost of drying oil, oxol is very economical and much more profitable than natural options.
How to dilute drying oil
When diluting semi-natural drying oil, all fire safety requirements must be observed. Dilution work should be carried out away from sources of fire, in well-ventilated areas or equipped with ventilation systems. How to dilute drying oil and is it worth resorting to?
When diluting oxols, one does not need to hope for the preservation of its initial physicochemical properties. Experts confirm that the process of dilution of drying oil does not always end successfully. During this procedure, you must always monitor the resulting reaction.
What to dilute with drying oil semi-natural? It can be dissolved with white spirit, turpentine, nephras and other synthetic fluids, which are used to dilute oil paints, in proportions of 1:10.
Combined drying oils
Combined drying oils are obtained by combining synthetic drying oils with vegetable oils after passing through heat treatment processes. Like semi-natural drying oils, differ in the percentage of oil and solvent. They are used in the manufacture of paints and varnishes, for the preparation of oil paints that are ready for use for painting work and for priming various products. The period of final drying is no more than a day.
How diluted combined drying oils
Diluting drying oil of this composition, it is necessary to adhere to the recommendations of specialists and observe the correct implementation of technological processes. Than to dilute the drying oil (thickened) of the combined formulations, it is not difficult to answer - with the same white spirit solvent. It is recommended to add only 1 part of the solvent to 10 parts of the base. After breeding, the loss of initial properties and qualities is inevitable. But there will also be an increase in flow properties, penetration and viscosity will improve, drying oil with such a composition can be used in areas that do not require high-quality processing.
This article answered questions about how to dilute drying oil at home, depending on the composition, what rules should be followed when doing this work, and what precautions should be followed.
