What is the combined brand K-3?
Do you need to process the wooden poles of the canopy to protect against moisture or paint the window frames inside and out, the combination paint K-3 is equally suitable for finishing works indoors or outdoors. It is necessary in the event that you need to mix plaster, soak wood, make oil paint, such as groundbreaking or white. Absolutely transparent, but it has a yellow color, light for Class 1 and with a darker shade for Class II.The oil of this brand gives a noble shade impregnated with wood with a characteristic luster.
K-3 is made from drying oils and is a 70% solution on the white spirit. Other petroleum solvents can also be used. In addition, the product contains a small amount of various modifiers( although some manufacturers do not add them), as well as a drier. The latter additive is also a catalyst for the oxidation process in oil, as a result of which drying of the drying oil layer occurs in the air. The formation of a solid film at a temperature of 18-22 degrees lasts about 24 hours, for work it is recommended to take small portions, the rest of the mass tightly closing the lid.
Combined K-2 grading oil - product characteristics
If external materials require high reliability of finishing materials, the rooms are more prized for their uniform drying and uniformity of the layer. Therefore, in paints designed to cover the walls inside the house, a combination of K-2 varnish is added. It is made from drying( like K-3), as well as semi-drying oils that mix in a certain proportion. As part of drying oil, dessicant is also present, to ensure the successful solidification of the product. The sale is 70% solution on white spirit.
Brand K-2 is completely transparent, and the shade of yellow is slightly darker than grade 1 K-3. For long-term storage, no more than 1% of the total weight of the drying oil falls into the sludge. However, it is not recommended to store it for more than 6 months. It solidifies this product, thanks to the desiccant, for 24 hours at a standard temperature of 18 to 22 degrees. For the layer to be level, and impregnation of the wooden surfaces - uniform, it is necessary to apply linseed oil on a previously prepared, dry, clean surface with a brush.
What is a combined drying oil?
Unlike natural, made on the basis of flax or sunflower oil and practically not requiring solvents, the combined drying oil is produced by the technology of oxidation of drying or semi-drying oils. Some brands contain in their composition and those and other oils, which are rarely more than 70% of the total mass of the product. The rest is 30% solvent. What is noteworthy, drying oil for coloring combined basically acts as a semi-finished product in the manufacture of oil paints, and not as a product for breeding ready-made.
For the production of drying oils, known as combined, only high-quality oils are used, so less solvent is required than for semi-natural oxal.
In some sources, "reliable" information is found that combined are those drying oils, which are a mixture of prepared vegetable oil with petroleum resin or linseed oil based on synthetic components. However, it is not. The name of our considered type of drying oil was received because it includes oils of different origin( linseed, castor, tung), or passed through different processing. For example, it can be a mixture of oxidized oil and heated by special technology.
