Features and composition of the solvent

R-4 solvent is an organic material that has a faint yellowish tint or is a transparent fluid without color. R-4 has a strong, unpleasant smell and is highly volatile, but it also lacks suspended particles, contaminants, and sediment.

The tool can be purchased in 0.5-1.5 liter glass or plastic bottles, canisters with varying capacities (up to 20 liters), and industrial containers with capacities ranging from 100 to 216 liters. The solvent maintains its properties because it does not react with plastic or glass.

Crucial! R-4 is widely used in daily life, on building sites, and in repair because it is affordable and simple to use.

It can be used to dilute a variety of paints and varnishes. The solvent shortens the time it takes for coatings to dry, increases their brightness and shine, and uses less money when painting.

The complex composition of R-4 consists of the following elements:

• Butylcetate (26%) – organic solvent from the class of complex ethers;
• Acetone (12%) – organic matter from saturated ketones;
• Toluol, or methylbenzole (62%) – belongs to the class of aren.

The composition’s butylcetate gives you the ability to improve the paint’s color and slow down the burnout process. In addition to providing good solvent interaction with enamels and varnishes, acetone and toluol enhance other R-4 consumer properties.

Specifications

The substance is regarded as a self-flammable volatile solution. It must be heated to a temperature of between +500 and +550 degrees in order to ignite spontaneously. However, the R-4 can ignite even at negative temperatures when exposed to direct fire or sparks (the flash happens at -10 degrees in a closed crucible).

Important: R-4 must never be used in close proximity to open fire sources.

The solvent’s technical attributes are registered in GOST 7827-74.

• The mass fraction of water on Fisher is up to 0.7%;
• Acid number – 0.07 mg of con/g;
• The number of coagulation is from 24%;
• Flying by ethyl ether-5-15;
• Density – 0.85 m³.

The GOST also specifies standards for the solvent’s dilution effect. There shouldn’t be any coagulation or mass stratification after adding to the LKM. There is no surface clouding and no appearance of whitish or matte spots as the paint diluted with premium solvent dries.

The scope of application

Breeding enamels based on vinyl chloride copolymers, epoxy resin, polyvinyl chloride chlorinated resins, and certain other film forms is perfectly suited for the solvent. A few examples of these enamels are KV-16, KH-112, KhSS-748, KhSS-759, and numerous others; the gray and protective enamel KV-124 is an exception.

The following repair materials can be used to achieve the required consistency by using a solvent:

• Lacques NC-269, NC-279, NC-292, NC-5108, EP-524;
• Shpatlevki NC-007, NC-008, NC-009, EP-0010, EP-0020;
• soils XC 059/068/077, MS 067, XV 062/079.

The R-4 is highly well-liked in the finishing and construction industries due to its ability to dilute large amounts of materials.

Crucial! It is without a doubt a composition that works with both natural and synthetic paints.

By acting as a degreaser, the solvent can help you swiftly and thoroughly eliminate fat patches, which weaken the base’s adhesion to the decoration. It evaporates instantly, leaving only the thinnest film that doesn’t require removal. R-4 aids in removing residue from various adhesive materials, allowing painting tools to be peeled off and reused.

Method of use

Small amounts of the solvent are added to the main ingredient and thoroughly mixed until the LKM reaches the ideal consistency. Water entering the liquid during operation is crucial because it will quickly mix with acetone, which could distort the final paint and varnish film’s color.

A cloth dipped in the solvent is used to wipe the surface in order to eliminate fat and pollutants. The old paint is removed with ease and speed using a spatula after the base has been thoroughly moistened with 4 and left for a while.

The best manufacturers

To avoid ruining paint or varnish, use only solvents from reputable brands. Prominent manufacturers strictly adhere to GOST and do not skimp on the quality of their initial raw materials.

The R-4 solvents are the most widely used in the current market:

1. From the Dmitrievsky Chemical Plant (Russia). The company strictly monitors compliance with the norms and rules in the release of products, using only the best raw materials.

Estimated consumption standards

It is crucial to know how much solvent will be used in order to purchase the appropriate amount of the product and calculate approximate costs. Various factors will determine the consumption:

• type of paint, enamel or varnish;
• density of the original composition;
• the deadline for its storage;
• application method;
• Environmental temperatures.

For instance, using a brush, roller, or spray gun will result in different amounts of paint being wasted and, thus, different amounts of solvent.

Counseling! The R-4 consumption increases with room temperature because of the faster evaporation.

The solvent’s average consumption per square meter of treated area is typically listed on the packaging. Additionally, the manufacturer provides approximations for the LCM dilution of the following kinds:

1. The KV-784 varnish is diluted by 50%if the spraying method is selected using a spray gun. The consumption will be 25% with airless spraying. This composition is not applied with a brush.
2. Soil XS-010. The consumption will be 40% with mechanized application and 30% with manual use.
3. Enamel PF-115 and PF-133. When applying with a brush, the solvent is spent in the range of 12-15%.
4. Enamel KV-124 and KV-125. For airless application, the consumption will be 35%, for compression – 50%.

The manufacturers advise sparingly adding a solvent to the primary mixture. This will precisely dose it and prevent overdilution, which degrades LKM’s properties. It is not possible to calculate R-4 consumption for other uses, such as degreasing, because the indicator is directly influenced by the location and level of pollution.

Safety precautions when working with solvent

Because R-4 is a toxic composition, you must strictly adhere to safety precautions when working with it. Breathing in the product’s vapors can have harmful effects on the body, including severe poisoning.

Crucial! Working with a solvent requires a well-ventilated space and a specialized respirator equipped with a coal filter.

Use rubber gloves and protective clothes to avoid skin contact, and wear glasses to prevent eye damage. The area is promptly cleaned with soap and lots of water as soon as it comes into contact with the skin. A visit to the doctor is necessary right away if dermatitis or other skin manifestations have appeared, or if there are indications of respiratory failure.

Transportation and storage

The solvent should only be kept for storage in narrow containers, such as bottles, canisters, glasses, or polymeric materials. Products from Uspur must guarantee total tightness and exhibit resistance against the solvent’s actual action.

R-4 is kept out of the direct sunlight and away from heat sources and appliances. One year from the date of production is the shelf life. In accordance with regulations for the transportation of class 3 hazardous materials, solvents are transported by rail or automobile.
