The second kind is manufactured in accordance with Soviet specifications, which were examined in 1972. Sales sizes have grown dramatically since the product’s foundational manufacturing stage, given the circumstances.

• This stage is due to the fact that having determined the overall composition of these products of chemical companies, it was possible to add to the multicomponent combination the unique properties that the solvent did not own the solvent before. The element was widely used in the manufacture of paintwork, which did not reach the current stereotypes.
• But despite the emergence of the latest, the most secure varnishes and paints for people and the surrounding world, which contains heavy compounds, a standard solvent is one of the favorites of this product.

In addition to being produced on its base as before, specific colors and varnishes are also used as diluents for various watery building materials.

Stronger and faster-acting than both White Spirit and Solvent 647, Solvent 646 is a multipurpose cleaning solution that can be used to remove paint, glue, and varnish. Its composition includes acetone and other solvents. While White Spirit is milder and is mainly used to clean brushes and thin oil-based paints, Solvent 647 is a slightly less aggressive formulation than Solvent 646, which is notable for its effectiveness in removing stubborn residues. Selecting the appropriate solvent for your particular requirements in a variety of paint and cleaning tasks requires an understanding of these variations.

The molecular structure of the solvent 646

Lighten 646 GOST 18188-72 possesses specific chemical element textures:

• Toluol – 50%;
• Ethyl alcohol – 15%;
• Butanol – 10%;
• Butylacetate – 10%;
• Ethyloclosol – 8%;
• Acetone – 7%.

Possesses unique qualities:

• The process of dilution. The method is used to dilute dense enamels, also paints, putty, film -forming varnishes, in order to achieve the necessary structure. Forms an even smooth cover on a painted plane.
• The ability to dissolve. Effectively dilutes the density, and also dissolves dirt, spots of paintwork from various planes.
• Poisoning qualities. When exposed to the high content of fumes in the atmosphere on people, probably loss of orientation, frequent dizziness and other negative impact. Great stress for the eyes, the respiratory system, stomach and intestines, liver are worse than. Long -term contact exacerbates the state of blood structure, consciousness is dull, leading to deplorable consequences.
• Hostile to certain types of plastic.
• Belongs to flammable solutions.
• By hazard category 3 – within reasonable limits in terms of influence on the atmosphere.
• Not frozen.
• Constant, does not change the color, does not lay in any way, does not settle.

Because the liner in this category has the highest electrochemical intensity, it must be used carefully to avoid contaminating the cleaned plane’s main spraying process.

It doesn’t require any further preparation because it is already made ready for use.

Paint, glue, and varnish removal is common use for solvent 646, a strong and adaptable solvent. Because of the mixture of alcohols, esters, and aromatic hydrocarbons that make up its main composition, it is very good at dissolving a wide range of substances. Solvent 646 is a well-liked option in both professional and do-it-yourself contexts because of this combination, which provides it with strong cleaning properties.

Solvent 646’s quick rate of evaporation is one of its main characteristics. In order to prepare surfaces for fresh paint or adhesive applications, it is especially helpful to ensure that surfaces dry quickly after cleaning. To prevent breathing in the fumes, which can be extremely potent and dangerous if used incorrectly, it should only be used in well-ventilated areas.

The distinctions between White Spirit and Solvent 646 are obvious. White spirit dissolves difficult materials more gently and is mainly made of aliphatic hydrocarbons. It’s frequently used for more delicate tasks or situations where a slower rate of evaporation is advantageous. Because of this, White Spirit is less appropriate for jobs requiring Solvent 646’s strong dissolving ability but safer to use on delicate materials and in areas with poor ventilation.

Conversely, Solvent 647 shares similarities with Solvent 646 but is designed to be less potent. Because of its slightly different chemical composition, it is safer to use on surfaces that could be harmed by the more aggressive Solvent 646. Because of this, Solvent 647 is a preferable option for delicate cleaning jobs where using stronger solvents could potentially harm the material being cleaned.

In general, the decision between White Spirit, Solvent 646, and Solvent 647 is based on the particular needs of the task at hand. While White Spirit works best for softer tasks, Solvent 646 is best for intensive cleaning and preparation, and Solvent 647 provides a medium ground for those who require a balance between strength and safety. By being aware of these variations, users can choose the best solvent for their purposes, guaranteeing efficient and secure outcomes.
