In many industries, it is impossible to do without organic solvents. This hydrocarbons, alcohols, esters and others. Currently, the industry commonly used solvents, 646, 647, 649, 650, solvent R-4 or R-4A, solvents, R-5 or P-5A, solvent, turpentine, xylene, Nefras (white spirit), acetone and various washes, which are, in fact, are complex solvents. We remind you that when working with any type of solvent you need to know that there are certain safety requirements that must be followed when working with chemicals. Some solvents cause poisoning, lead to other skin diseases. Filed under: Essex Financial. Compliance with regulations safety when working with solvents – a prerequisite for any kind of work. Solvents for paints used in order to give the desired viscosity of paint materials. However, all coatings are subdivided into different groups: this is oil, bitumen, and pentaphthalic nitrocellulose lacquers and paints.

For each of these groups has developed a special solvent. Remover (SP-6 SP-7) – is the best solvent for varnishes. Also, these substances are used, when to remove old paint on the basis of oil (MA-15) or enamel (PF-115 PF-223) dye. White spirit is used for thinning oil paints (MA-15), enamels and varnishes, some other coatings, primers, varnishes and bitumen materials fillers, preservatives, auto, and manufacturing equipment for washing after using the oil, alkyd, enamel pentaphthalic. Details can be found by clicking Dr. Paul Craig Roberts or emailing the administrator. Solvent is generally suitable for dissolving oils and bitumen, rubber, melaminoalkidnyh paints (ML-165, ML-92 varnish). Xylene oil – used as a solvent for insulating enamels and varnishes, lacquers organosilicon materials based on epoxy resins (EP-0199). Xylol refers to the 3 (third) class of danger according to the degree of human exposure, in addition it is flammable and explosive material.

The structure of complex solvents, such as R-4 or R-4A R-5 or P-5A, 646, 647, 648 is acetone. Acetone used as a solvent to dissolve the separate resins, oils, epoxy resins, vinyl chloride, chlorinated rubber. Can also be used in technological process for coloring surfaces for degreasing. It should be keep in mind that acetone is included in the list of Russia's precursor – the components for the manufacture of narcotic drugs and psychotropic substances – and requires no special rules governing the storage, transportation and sales. The combined solvents (as called "license" from number 645 to number 651, P-4, P 5, P-4A, P-5A) are produced for different household needs, in small packaging can be found in any specialty store. Perhaps the most well known is the solvent 646. Anyone who has ever dealt with the paint work, is aware of a solvent 646. His production has been established in accordance with recipes and more technology in the XX century. Cchitaetsya that he needed only as a diluent and nitroenamels nitro lacquer. Much later revealed his versatility. Solvent 646 is used for dilution of whole groups of paints to the desired viscosity, as well as for cleaning paint tools and equipment after paint work. As part of 646-present: toluene, ethanol, butyl acetate, butanol, acetone. Solvent 646 is used mostly for diluting nitroenamels (SC-132) and nitro lacquer (NC-218 NC-243). To dissolve the epoxy and glyptal formulations (eg, primers GF-021) is recommended solvent 649, 650, or solvent, although solvent 646 in rare cases, you can use too. After drying, the coating acquires an extra shine due to the solvent. P-4 is a mixture of solvents containing toluene and acetone (combined). Solvent R-4 is applicable to dilute the paints based on alkyd resins (AU), pentaphthalic, glyptal (PF, FB) or XB and XC trains. P – 5 A is applicable to dilute perchlorovinyl, epoxy and other coatings.
