One of KHIMIK’s focuses of activity is to develop and manufacture special products to address challenges with the operation of various vehicles.

Products for transport applications developed by our company increase the efficiency of vehicles and machines, extend their service life, improve the quality of routine and repair operations, provide better safety and comfort during the operation of vehicles in harsh weather and climatic conditions.

Operating fluids

The key characteristics of a car – comfort and safety – are only achievable provided that all of the car’s components and units function properly. It is difficult to overestimate the importance of the brake system, the cooling system of a vehicle’s major unit – the engine, as well as the windshield cleaning system. Their proper functioning is guaranteed through the use of respective operating fluids, and it is on the quality of these fluids that the service life and efficiency of a car’s systems depend. In the end, all of this determines the most important thing about the operation of vehicles – road safety. At KHIMIK, we therefore place special emphasis on consumer properties, parameters, and quality of our operating fluids, which can be categorized into the following groups:

  • Windshield washer fluids
  • Concentrated windshield washer fluids

Windshield washer fluids

Alcohol is the main ingredient in windshield washer fluid. Alcohol prevents fluid from freezing in winter and helps it cope with organic dirt on the windshield. It is utterly important to check that isopropyl or ethyl alcohol is used. These are the only alcohols permitted by the law, whereas methyl alcohol is prohibited, since it is a nerve agent. Since the production of ethyl-based products is subject to stringent state control, nonfreezing liquids are usually produced with isopropyl alcohol. It, however, has one disadvantage, which is odor nuisance. So another important ingredient in windshield washer fluid is a fragrance, which is capable of disguising the odor of alcohol but, unfortunately, cannot fully remove it.

The absence of odor, however, is not attributable to a fragrance alone. Manufacturing technology, the right choice and combination of ingredients are all essential for the production of a good windshield cleaner. KHIMIK, therefore, pays great attention to the development, creation, and testing of products within this category.

Here is the specification for windshield washer fluids produced by KHIMIK.

  • Windshield washer fluids are intended for cleaning windshields of a vehicle with the use of a washer.
  • When stored and transported at temperatures below their freezing point, windshield washer fluids can freeze and fully recover all their properties when defrosted.
  • Windshield washer fluid is an aqueous solution of alcohol with active admixtures and dye.
  • Windshield washer fluids shall meet the Unified Sanitary Requirements of the Customs Union, and the requirements of GOST R 51696 and Specification 2384-097-00205357-2008.

The physical and chemical quality indicators of windshield washer fluids shall match the requirements and standards in the table below. Note: Standards marked with * apply to a concentrate diluted with distilled water at a ratio of 1:3.

Concentrated windshield washer fluids

The specification for windshield washer fluid concentrates produced by KHIMIK.

  • Windshield washer fluid concentrate is intended for cleaning windshields and headlamps of a vehicle with the use of a washer.
  • Windshield washer fluid concentrate is an aqueous solution of isopropyl alcohol with active admixtures and dye.
  • Windshield washer fluid concentrates shall meet the Unified Sanitary Requirements of the Customs Union, and the requirements of GOST R 51696 and Specification 2384-052-54804491-2007. The quality indicators shall match the standards in the table below.

Coolants

Modern cars are obviously equipped with many standalone systems that support and ensure the safe operation of a vehicle. Each of the systems requires timely and quality service, where the change of the main operating fluid is a must-do. The cooling system is one of the main systems of a car since it belongs to its main unit and its heart – the engine – whose functioning determines the mobility of a vehicle.
KHIMIK specializes in producing high-grade coolants for all available types of engines.

Solvents and thinners

Among other focuses of activity, the company develops and produces various solvents and thinners for industry, transport, and construction applications. The products produced by the company in this field can be categorized into the following groups:

Solvents (active solvents) – liquids that completely solve film forming substance and evaporate in the drying process. Paint solvents are compounds of different chemical nature such as aromatic, aliphatic hydrocarbons and their mixtures, simple and compound ethers, ketones, alcohols, halogenated hydrocarbons, etc.

Thinners (co-solvents) are liquids that do not solve film forming substance by themselves but, when mixed with true solvent, are capable of reducing the viscosity of a solution or imparting some special properties. A thinner to solvent ratio has to be thoroughly selected in order to obtain the best properties of paint and the optimal quality of a finished coating.

Solvent composition can also affect the stability of pigmented paints. Solvent must not displace dispersant or sorbed polymer molecules from the surface of pigments and fillers so as not to cause settling or coagulation of the pigment portion.

Both solvents and thinners must be completely removed from the coating in the course of drying after a specified period of time. Since various components in solvent mixtures are of different volatility, it is important to ensure that the most active solvents of the mixture have the worst volatility (the last to remain). Otherwise, polymer will prematurely coagulate as it becomes less soluble in the drying process, resulting in a friable coating with poor protective properties. Moreover, the escape of remaining co-solvents will be hampered.
The volatility of solvents used must be suitable for application and drying conditions. When applied by spraying (especially air spraying), small particles of paint lose some solvent on their way to the surface being painted. If losses are excessive, paint particles will become too viscous, and the coating will not be uniform.

Multiple surface defects can occur when solvents evaporate from the coating too fast. In a thick coating, the fast formation of a surface film will cause buckling (as it happens in case of intensive air exchange or draught). The fast evaporation without a surface film being formed will cause shagreen. This is due to the fact that evaporating solvent captures coating material as it goes up from within the coating. While material enriched with solvent goes up in some areas, depleted material goes down in other areas, and the increasing viscosity does not allow the coating to even out. Moreover, the fast evaporation of solvent can result in the paint surface cooling down, moisture in air condensing on the surface, and the surface layer becoming saturated with water. For nitrocellulose coatings, this can cause the blushing of the surface film.

Defects of a coating do not merely worsen its appearance but also significantly impair its protective properties due to thickness loss in the defect area, porosity, etc.

Wood protection

Wood, as a natural construction material, has many advantages: low cost, considerable strength, ease of processing and high thermal and acoustic insulation properties. However, with all these advantages, wood is exposed to moisture, temperature and ultraviolet radiation, making it one of the most short-lived materials and limiting its use in construction.

Various types of paintwork materials are used to preserve this unique building material.

Each of the materials has its own field of application and is designed to solve specific tasks that face the builder:

  • protective and decorative coatings (compositions) form a protective film, which, unlike paint, does not hide the structure of wood and allows wood to “breathe” (which significantly slows down rotting processes); at the same time, they are finishing;
  • bio-based fire-retardent treatments serve to protect wood from fire; the fire protection is generally understood as the reduction of flammability and fire hazard of various materials (finishing and facing, structural, etc.) and products (decorations, doors, partitions, roof structures, etc.) based on wood.

Protective decorative coatings

Protective and decorative coatings (compositions) appeared on the paintwork market not so long ago – about 50 years ago, and have been actively used in the last decade.

KHIMIK has been engaged in producing protective and decorative compositions for more than 10 years, and the alkyd-resin products are now being the main direction of production. Protective and decorative compositions are similar to ordinary paints in that they are solutions of film-forming substances in organic solvents or water with pigments and fillers.

The principal differences between the protective and decorative compositions and ordinary paints are as follows:

  • presence or absence of a moisture permeable film, which significantly reduces wood rotting;
  • introduction of fungicides into the formulation; depending on the composition type, fungicides either prevent subsequent infestation or control existing infestation;
  • significantly less cracking of the painted surface, as on average the thickness of the paint layer is 5 times greater than the thickness of the layer of protective and decorative composition.

The second difference of the market segment of the protective and decorative compositions is the lack of a unified terminology in the market. One and the same product can be called both protective and decorative composition, antiseptic and treatment. We have adopted the following system of definitions for ourselves:

  • Protective and decorative compositions are binder compositions with two functions: protective and decorative.
  • Protective compositions (treatments) are aqueous solutions of fungicides and/or insecticides intended only for protection against bio-damage and insects.

These products are manufactured under the KRONA brand name.

Alkyd compositions were the first to be invented in this market, and they are most often used for painting outer surfaces. And there is a rational basis for this – the molecules of alkyd compositions are smaller than the acrylic ones in size, and therefore they penetrate deeper into the wood and are less susceptible to abrasion compared to acrylic products. There is also cross-linking of layers in the process of drying alkyd products (layers are joined at the level of molecules), and as a result a solid film is formed.

Acrylic compositions are solutions of polymers in water with pigments and fillers. The products are odorless and therefore their market share is constantly growing as more and more consumers are replacing alkyd products with acrylic ones. The film of acrylic compositions is less durable compared to alkyd products, as there is not a chemical cross-linking process, but physical adhesion of one layer to another, but at the same time the resulting characteristics are sufficient for effective work of the product indoors. The principal difference between protective and decorative compositions and treatments is the concentration of fungicide in the formulations. The protective and decorative compositions have a sufficient amount of fungicides for subsequent protection against bio-damage. At the same time, increased concentration of fungicides is introduced in treatments in comparison with protective and decorative compositions. This concentration is sufficient not only for further protection against bio-damage, but also for the control of existing ones. Treatments were invented to reduce the cost of work on concealed structures where the decorative function is not important.

All treatments are divided into 3 large groups:

  1. mitigating bio-damage
  2. mitigating insect infestation
  3. preventing wood from ignition

All fire retarders can be categorized by the type of medium that forms in the wood after treatment. If alkaline salts are used (the most common option in the market), an alkaline medium with pH > 8 is formed in the wood, and this medium slowly destroys the wood lignin, if acid salts are used, the weak acid medium is formed in the wood, which is very close to neutral (pH about 5), that has no effect on wood destruction. Alkali affects wood in the following way – it penetrates into the wood surface layers (2–3 mm) and fixes in it. In case the wooden surface is moistened again, the alkali will penetrate even deeper into the wood, as water performs transport functions in the wood structure. During numerous “wetting-drying” cycles, alkalis can penetrate into the wood to a depth of about 5 cm, destroying the wood structure, the lignin that binds the cellulose cells together at the micro level and provides the material strength. The wood fibers irretrievably lose their bond between each other, the material becomes loose, porous like a sponge, absorbing moisture and thus even more susceptible to bio-damage.

Oil & Gas

1833_cover.jpg
  • Internal smooth (antifriction) pipe coatings
  • Pipeline corrosion protection
  • Paintwork materials for tanks with oil products
  • Materials for auxiliary operations

One of the priority areas of the company's activity is creation of materials for anticorrosion protection of oil-and-gas production equipment: pipelines, shaped elements, shut-off valves, vessels for oil products storage, metal structures of various applications.

The complexity of the task is specified by the high corrosiveness of the environment in which the equipment is operated. Crude oil and the formation water emulsified in it contain dissolved salts, carbon dioxide and hydrogen sulphide. The most dangerous is the hydrogen-sulphide corrosion, which even corrosion-resistant grades of steel cannot resist. Additional negative factors reduce the service life of pipelines, including: periodic and constant mechanical loads, higher temperature, high abrasivity of environment, hardness deposition and asphaltene-resin-paraffin deposits (ARPD), and the use of various chemical reagents for pipe cleaning. The tubing and in-field pipelines are operated under the most severe conditions.

The multifactorial nature of the task and considerable differences in the composition of the corrosive medium in different fields complicate the creation of the paintwork material which provides reliable corrosion protection. When creating materials that can withstand the corrosive medium for a long period, we take into account the complete range of conditions effecting the coating service life. It includes the operating conditions of a coating such as the chemical composition of the medium, temperature and pressure, mechanical stress, and climatic conditions at a given location. Coating conditions: methods and quality of surface preparation, used equipment, modes of application and curing, as well as methods of transportation and storage conditions of finished products.

Developed materials are thoroughly tested for compliance with the requirements of regulatory documentation. The whole range of tests is carried out: physical and chemical, climatic, confirming the compliance of the declared properties of the material and coating with the actual ones. Tests are carried out during the development process using the in-house equipment, and then in industry institutes that authorize the use of materials by specific customers.

The used technologies enable to adapt a number of technological characteristics, such as rheological properties, curing time, to the process equipment of coating plants.

When developing paintwork materials for industrial use, we strived to minimize labor costs during their application. For this purpose the paintwork materials have been developed which allow to apply the coating of required thickness in a single layer. Rheological properties of these materials allow to obtain coatings up to 800 µm thick on vertical surfaces, and high anti-corrosion properties, chemical resistance and excellent adhesion provide long service life and performance characteristics of the coating.

1.1. Pipeline corrosion protection

oil-pipelines-isolated-on-blue-sky.jpg

One of the main reasons for high accident rate of in-field oil pipelines is corrosion caused by the joint action of corrosive medium and mechanical loads. Corrosion damage causes up to 30% of pipeline failures. In this regard, it becomes impossible to ensure safe operation of the pipeline systems and increase their service life without addressing the issues of corrosion protection of the outer and inner surfaces of pipes and welded joints.

One of the methods of the pipeline corrosion protection is insulation of metal surface against the corrosive medium by polymer coatings, including the paint ones. The applied paintwork materials should be very resistant to the pumped medium at temperatures and pressures of pipeline operation, and technologically simple when applied and transported. As a rule, two-component thixotropic materials are used, enabling to get a coating of the required thickness in one pass.

Metal corrosion protection

Development of corrosion protection materials is one of the core activities at KHIMIK. The company has developed and introduced various anticorrosive materials to protect vehicles and machines in harsh climatic conditions, and also to protect metal structures used in transport infrastructure.

  • Anticorrosive protective coatings
  • Rust converters

When developing these materials, which are capable of withstanding long-time exposure to a corrosive medium, the whole mix of conditions affecting the life of coatings is considered. It includes the operating conditions of a coating such as the chemical composition of the medium, temperature and pressure, mechanical stress, and climatic conditions at a given location. Application conditions: surface preparation methods and quality, coating application equipment, hardening and storage conditions, and mode of transportation.

Solvents, diluents

0f0c62ce873d99e8ccf4be880cef0039.jpg

One of the company's activities is development and production of various solvents and dilutants used in industry, transportation and construction. The products of this direction produced at the enterprise can be conventionally divided into the following groups:

  • Solvents. Solvents are the liquids that completely dissolve the film-forming agent and evaporate during the drying process. Compounds of various chemical nature such as aromatic, aliphatic hydrocarbons and their mixtures, simple and compound ethers, ketones, alcohols, halogen derivatives of hydrocarbons, etc., are used as solvents for paintwork materials.
  • Diluents (cosolvents) are liquids that by themselves do not dissolve the film-forming agent, but when mixed with a true solvent can reduce the viscosity of the solution or give it any special properties.

Selection of the diluent/solvent ratio is necessary to obtain best properties of the paintwork material and quality of the finished coating. The solvent composition can also affect the stability of pigmented paintwork materials. The solvent should not displace dispersants or sorbed polymer molecules from the surface of pigments and fillers so as not to cause settling or coagulation of the pigment portion. During the drying process, both solvents and diluents should be completely removed from the coating within the required time. Considering the fact that different components of the blended solvents have different volatilities, it is important that the worst volatility is that of the most active solvents in the blend (they should remain the last). Otherwise, the coating will coagulate prematurely during the drying process due to the decreased solubility of the polymer, resulting in a loose coating with poor protective properties. In addition, it will be difficult for the cosolvent residues to escape.

The volatility of the solvents used should be suitable for the coating application and drying conditions. When applied by spraying methods (especially pneumatic), fine paint particles lose part of the solvent on their way to the surface to be painted. If the losses are excessive, the paintwork particles will become too viscous and a continuous coating will not be obtained.

Too rapid evaporation of solvents from the coating can lead to a variety of surface defects. If the coating thickness is large, rapid formation of the surface film will lead to wrinkling (it often occurs in case of intensive air exchange or drafts). Rapid evaporation without the formation of a surface film will result in shagreening. It is related to the fact that the evaporating solvent, as it rises from the depth of the coating, takes the coating material with it. In some areas the solvent-rich material rises to the top, while depleted material falls to the bottom in other areas, and viscosity build-up prevents the coating from leveling out. In addition, rapid evaporation of the solvent can lead to cooling of the paintwork material surface, condensation of air moisture on the surface and saturation of the surface layer with water. This leads to whitening of the coating film for nitrocellulose paintwork materials. Defects in the paintwork do not just deteriorate its appearance, they significantly reduce its protective properties due to reduction of the coating thickness in the area of defects, pore formation, etc.
