Urethane varnish, which is also called polyurethane, has unique qualities of cost-effectiveness and high reliability of the layer formed. It can be used to protect surfaces made of wood, metal and mineral materials from chemical and mechanical influences. Among the latter, it should be noted: brick, stone, concrete and concrete tiles.
The concept of "polyurethane" is more correct than "urethane varnish", because such mixtures are polymeric materials. One of their main tasks is multifunctional surface protection.
Characteristics of "Elakor-PU" parquet lacquer
This composition is intended for wooden surfaces, including parquet. For 10 kg of the mixture you will have to pay 260 rubles. It is possible to transport and store products at temperatures from -40 to +25 ° C, which is very popular with consumers. This varnish is designed to be applied to wood and forms a chemical bond with its fibers, providing the strongest possible adhesion to wood.surface. As a result, the layer of wood is significantly strengthened. Among the main characteristics of the composition, it is worth highlighting a very fast curing ability (after all, the next layer can sometimes be applied after 3 hours), chemical resistance and particularly high mechanical wear resistance. This varnish is used as a varnish coating for wood and parquet in civil, public and administrative, as well as industrial premises. In this case, a high foot load can be placed on the floor. The surface may even be chemically attacked.
Additional properties
Urethane parquet varnishes of the type described above can be applied to surfaces that have been previously treated with antifungal compounds. It can be applied to fire-retardant impregnations. Due to the fact that the varnish has the qualities of wear resistance, the surface acquires the characteristics that are less susceptible to scratches and the accumulation of dirt, as well as microorganisms. Cleaning can be carried out with any detergents, if necessary, disinfectants and antibacterial preparations can be used. These varnishes have one drawback, which is that they give the surface a yellowish amber tint, naturally, the color of the parquet wood will also change.
Characteristics of varnish for concrete "Lak-60"
You can buy a 10 kg package for 275 rubles. After hardening, this composition forms a hard surface, whichcharacterized by high protective qualities. The base becomes resistant to chemical and mechanical stress. Objects of application: warehouses, production shops and tanks, also technical pools. This polyurethane varnish withstands constant contact with water, alkaline, acidic electrolytes and mineral oils. It can be used to seal and dedust the surface of concrete, giving it the quality of impact resistance.
Things to remember
Polymeric floors can be operated at temperatures from -60 to +120 °С. This urethane varnish has many advantages, namely: high resistance to chemicals, the possibility of application at negative temperatures down to -30 ° C, the possibility of operation in a day and full mechanical load after three days, as well as a rather short layer-by-layer drying, which is achieved after 6 hours. After purchase, you can immediately begin repair work, as the polyurethane varnish is completely ready for use. If applied to a polymer coating, the consumption will be approximately 140 g/m2.
Reviews about the varnish for metal "Elakor-PU"
If you need a urethane varnish, then you can purchase one that is intended for applying and protecting metal from corrosion. According to users, this one-component composition has a glossy transparent sheen and is immediately ready for use. The dry residue is approximately 60%. Application followsto carry out on a dry, pre-painted surface or a primed base, if there is a need to obtain an anti-corrosion coating. After the completion of the polymerization stage, the varnish will form a fairly strong and hard, but elastic and transparent film, which is highly wear resistant. Consumers emphasize that low-alloy and carbon steels, cast iron, galvanized steel, aluminum and its alloys and copper can be used as rough bases.
The objects of application are tanks for storing solutions of acids, oil, diesel fuel, water and alcohols. Application can be carried out on the inner surfaces of the car. This varnish is used for metal floors in the field of equipment use. Buyers note that urethane varnish for metal can be operated at a fairly wide temperature range: from -60 to +80 ° C. If it is necessary to clean the surface, you can use the method of steam supply at temperatures up to +180 °C. This composition is allowed for use in food industry enterprises, in housing construction and in nuclear energy.
Features of the varnish "Eco-Lac-60"
Urethane varnish, reviews of which are only the most positive, can also be used in the food industry. This is true for the above title. This composition can be stored and transported at temperatures from -40 to +25 °C. Objects of application are tanks for drinking water, dry food storagelike flour or grain. Application surfaces can be concrete, mineral bases, aluminum and its alloys, as well as carbon and low alloy steels. For a bucket (10 kg) you will have to pay 290 rubles. If you need to purchase food varnish in large volumes, you should pay attention to containers up to 200 kg.
Features of urethane yacht varnish
Urethane Yacht Varnish is available as a urethane-alkyd and alkyd-urethane marine finish that dries quickly and contains less organic type solvent. Excessive evaporation of harmful chemicals is reduced due to the presence of plasticizers in the composition. The surface has high flexibility and resistance to sudden temperature changes. This is practical if the cottage has a floor heating system. Urethane varnish, the characteristics of which are important to know before purchasing, is an alkyd-urethane ship varnish, which can only be used for outdoor work, as it is toxic.
Characteristics of Etheral varnish
Eteral urethane lacquer is a solution of urethane pseudoprepolymer cured upon contact with atmospheric moisture. The main areas of application are the possibility of applying to concrete, metal, floor surfaces, as well as wood. The main advantages are durability, comprehensive protection and economy. With proper preparation of the base and application according to the technology, the varnish can be used infor 30 years. At the same time, it will retain its technical and operational qualities. This urethane compound performs several functions at once, protecting the surface from moisture, mechanical damage and chemicals.
The surface can be operated at temperatures from -60 to +90 °С, which indicates unpretentiousness to conditions. This compound, after hardening, can protect surfaces in production workshops, as well as outdoors in the northern regions. The base is resistant to abrasion and can withstand heavy loads.
Features of using Etheral lacquer
Etheral can be applied with a spray gun, roller or brush. In this case, the temperature should be equal to from -20 to +40 ° С, while the air humidity can be equal to a figure in the range from 30 to 98%. With a single layer application per square meter, approximately 50 g of the composition will go. The number of layers can be up to four.
After opening the container, the varnish can be used within 24 hours, these are the storage conditions that should be followed. If it has not been used to the end, then the surface should be filled with a moisture thinner or toluene, the layer height of which can reach 2 cm. After that, the lid closes tightly and the varnish is left in this state until the next use is necessary.
