Thinner 646

Solvent 646 is known, in fact, to anyone who has experienced repair work. This product of the oil refining industry has been produced for a very long time, and over the years of use it has significantly expanded its field of application in both domestic and industrial spheres.

Application of

With solvent 646, varnishes and paint are adjusted to the required working consistency. They also effectively cleaned the paintwork and remove stains. When painting with paint and varnish materials, using a solvent 646, a smooth, shiny film is formed. In the photo and video you can see how it is used in practice.

Solvent composition 646

Thinner 646 is a clear or slightly yellow liquid with a strong odor, which contains various organic compounds. The basis of the solvent is:

• Toluene( 50%)
• Butanol( 15%)
• Ethyl alcohol( 10%)
• Butyl acetate( 10%)
• Ethyl cellosolve( 8%)
• Acetone( 7%)

The chemical composition and properties of the solvent646 allowed it to be effectively used and applied in many processes. Cheap solvent, which is sold, practically, in every construction shop. Simplicity of application allows using it wherever work is associated with painting, puttying or priming.

Disadvantages of

However, let's not forget about the disadvantages of the solvent 646. Some substances present in it can easily ignite. Therefore, the container in which the liquid will be located should be sealed and not in contact with direct sunlight. There is a sharp unpleasant smell. It is toxic, therefore can negatively affect human health. You can protect yourself by wearing protective equipment on the body part, subject to possible contact( hands, face).

Solvent specification 646

Also, it is worthwhile to dwell on some technical characteristics of the solvent 646, knowing that handling it will not be dangerous.

1. Self-igniting at a temperature of +403 degrees Celsius.
2. Starts boiling at +59 degrees Celsius.
3. Flashes at -7 degrees Celsius( if there is an open flame).
4. It does not thicken and does not freeze. The density of the liquid is 0.87 g / cm. Cu.

Thinner 646 is an active chemical, so use it carefully, otherwise there is a risk of damage to the lower layers of the coating.

When used in domestic needs, the descriptions and recommendations given above fully describe all the risks and benefits of the solvent 646. But, do not forget the use of solvent in the manufacturing sector. Here you need to carefully read the information specified in the fluid certificate:

• , the mass fraction of the water contained is 0.09%;
• parameters of the acid number - 0.06 mg KOH / g;
• relative volatility - 12;
• the coagulation number is - 40 g / o;
• action of the dissolving substance - after removal of the stains there are no dull and whitish outlines;
• Specific gravity of solvent 646 - 0,68 kg / l.

These values ​​will not tell a simple man in the street, however, a technologist at the enterprise, based on passport data, can draw an expert opinion on the advisability of using a solvent in the production process.

According to reviews, the solvent 646 has no alternative, because its advantages clearly exceed the disadvantages. To judge its indispensability and relevance, you can look at any painted surface, when painting it, it was always used.
