What is solvent 650 used for - technical characteristics
When using paints and varnishes, traces often remain on items of clothing, tools or hands. For cleaning, we strongly recommend using a certain composition, which is called a solvent or even a solvent.
By the name it is already clear that for each type of paint and varnish material, compositions are used that coincide in base. Thinner 650 is an organic, clear liquid that has a pungent aroma.
It is a mixture of carbons that evaporate easily.
Do you know what Thinner 650 is for? The main area of application of the liquid was the dilution of paints and varnishes to the required level of viscosity, which provides the maximum degree of hiding power, as well as uniformity during application. This is a special mixture that consists of organic components that dissolve certain types of paints and varnishes, and this is a solvent 650.
It is used:
Please note that information about the operational life of the liquid is printed on the surface of the original packaging, and the composition can be stored sealed for 2 years.
During long-term storage, the concentration of volatile esters decreases.
The main area of use of the liquid is that it is used to dilute paints and varnishes to the required viscosity, which ensures the maximum degree of hiding power, as well as uniformity of application.
For high coagulation (up to 60%), low water content (no more than 2%), solvent 650 is valued, and the composition is made on the basis of butanol and it also contains xylene (obtained by distillation of coal-type tar or petroleum products), which are highly soluble and volatile. Chemical qualities limit the scope of the product, and the liquid itself is very poisonous, even aggressive. The acidity will not exceed 0.
1 mg KOH / g, and the volatility index is 25. Ideal transparency is obtained, and the hydrocarbon mixture should be free of solid inclusions and suspension.Unlike xylene, toluene and acetone, after drying the solvent does not form a whitish film on the surface. Chemical qualities will limit the scope of the product, and the liquid itself is very toxic.
The liquid must be introduced into the paintwork material immediately before application, measuring out the required amount of paintwork material and diluent.
The ratio of the components must be strictly observed in order to obtain the required degree of viscosity. The composition will be ideal for bodywork, it perfectly dissolves primers, old coatings and putties. Apply by spray or brush, and the best way to clean treated surfaces is to use a rag.
Manufacturing companies make solvent 650 according to TU and GOST. In terms of chemical composition, the requirements are almost the same.
When choosing a liquid, it is important to pay attention to:
It is interesting that the solvent №650 for dilution is sold by many manufacturers:
Solvent 650 is produced in 5 and 10 liters, the packages are soft, and the bottles have a volume of 1/2 and 1 liter. Buy a liquid that dissolves enamel should be from popular manufacturing companies.
This will become a guarantee of quality.
Knowing about the chemical composition of solvent 650 and its technical characteristics, you can determine the concentration of substances for dissolution. To a large extent, the consumption will depend on the method of using the substance, as well as the conditions of use. It is imperative to read the recommendations of manufacturers of paints and varnishes.
In order not to get into a situation with vapor poisoning, organic liquids must be closed as tightly as possible.
This is also largely due to the fiery danger of the substance, and the vapors themselves are highly flammable. The containers do not need to be left in the sun to eliminate the risk of explosion of such a mixture. Diluent solvents are used in well-ventilated rooms, where forced draft and ventilation systems work. When working, make sure that the hydrocarbon mixture does not get on the mucous lips, eyes, as well as open areas of the skin. The solvent must be washed off with warm soapy water.
During the disposal process, it is strictly forbidden to pour the dissolving liquid into the sewer system, into the ground or open types of water bodies.
Among thinners The 640th group solvents 646, 647 and 650 have become popular. The first is used as a diluent for body enamel, nitro varnishes, putties and paintwork materials, as well as organosilicon paints. It consists of a solution of alcohol, aromatic hydrocarbons, volatile types of ether, ketones that quickly evaporate in open space, as well as universal acetone. The thinner will give paint coatings an excellent gloss, which promotes uniform polymerization of the protective film, which provides the viscosity of the paint material required for ideal hiding power.
A solvent like 647 contains toluene, which can dissolve nitrocellulose components. The base is a mixture of ethyl and butyl alcohol, as well as volatile esters. There is no acetone in solvent 647 and toluene is used instead.
By purpose, the liquid is very similar to solvent 650, and in the same way differs from solvent 646, which is often used to dilute nitrocellulose paints and varnishes used in the construction industry, as well as NTs-097 primers. It is added to enamels when it is not required to apply a brush or spray gun for working viscosity.
It is not correct to compare which of the thinners (646 or 650). The scope of use of 646 is much wider, and it is comparable with a huge number of paints and varnishes, including cellulose-glyphthalic nitrate and urea-formaldehyde. But 650 thinner is ideal for fast and high quality dissolution of acrylic, glyphthalic, epoxy and nitrocellulose paints and varnishes used in the automotive industry. This is the main difference between paint thinners. Composition No.
650 is ideal for high-quality and fast dilution of acrylic, glyphthalic, nitrocellulose and epoxy paints and varnishes. In certain cases, this type of solvent, such as 646, is successfully used in order to dilute putties, paints and varnishes often used in everyday life. When choosing a thinner, knowing what 646 and 650 are, you need to read the recommendations of the manufacturers of paints and varnishes.
