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:
- mitigating bio-damage
- mitigating insect infestation
- 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.

Development of corrosion protection materials is one of the core activities at KHIMIK. The company has developed and applied to production various anticorrosive materials to protect infrastructure facilities, metal structures for various purposes and building materials.
- Corrosion protection
- Paints & Varnishes
- Epoxy materials
When creating these materials, which are able to resist the action of corrosive medium for a long time, the whole complex of conditions affecting the service life of the coating is taken into account. 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
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.
