Urethane varnish, also called polyurethane, has unique qualities of economy and high reliability of the formed layer. With its help, it is possible to protect against the chemical and mechanical effects of surfaces made of wood, metal and mineral materials. Among the latter, it should be noted: brick, stone, concrete and concrete tile.
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 parquet varnish brand "Elacor-PU"
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 intended for application to wood and forms a chemical bond with its fibers, providing maximum adhesion to the surface. As a result, the wood layer is significantly hardened. Among the main characteristics of the composition, it is necessary to single out a very fast hardening 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. At the same time, a high pedestrian load may be on the floor. The surface can even be exposed to chemical influences.
Additional properties
Urethane parquet varnishes of the type described above can be applied to surfaces that have previously been treated with antifungal compounds. It is possible to apply to fire-retardant impregnations. Due to the fact that the varnish has the qualities of wear resistance, the surface acquires characteristics that are less susceptible to scratches and accumulation of dirt, as well as microorganisms. Cleaning can be carried out by any detergents, if necessary, you can use disinfectant and antibacterial drugs. These varnishes have one drawback, which is expressed in the fact that they give the surface a yellowish amber hue, of course, the color of the wood parquet will also change.
Characteristics of varnish for concrete "Varnish-60"
You can buy 10 kg packaging for 275 rubles. After hardening, this composition forms a solid surface, which is characterized by high protective qualities. The base gains resistance to chemical and mechanical stress. Objects of application: warehouses, production shops and tanks, as well as technical pools. This polyurethane varnish stably undergoes constant contact with water, alkaline, acidic electrolytes and mineral oils. It can be used to seal and dust the surface of concrete, giving it the quality of impact resistance.
Things to remember
Polymer floors can be operated at temperatures from -60 to +120 ° C. This urethane varnish has many advantages, namely: high resistance to chemicals, the ability to apply at negative temperatures up to -30 ° C, the possibility of operation after a day and full mechanical load after three days, as well as a fairly short layer drying, which is achieved after 6 hours. After the acquisition, you can immediately begin repair work, as the polyurethane varnish is completely ready for use. If applied to a polymer coating, the flow rate will be approximately 140 g / m 2 .
Reviews about the varnish for metal "Elacor-PU"
If you need 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 gloss and is immediately ready for use. The dry residue is approximately 60%. Application should be carried out on a dry, pre-painted surface or primed base, if there is a need to obtain a corrosion-resistant coating. After the completion of the polymerization step, the varnish will form a fairly strong and hard, but elastic and transparent film, which is characterized by high wear resistance. Consumers emphasize that low-alloy and carbon steels, cast iron, galvanized steel, aluminum and its alloys and copper can be used as rough substrates.
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 surface 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 you need to clean the surface, you can use the steam supply method at temperatures up to +180 ° C. This composition is allowed for use in food industry enterprises, in housing construction and in nuclear power engineering.
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 name. This composition can be stored and transported at temperatures from -40 to +25 ° C. The objects of application are tanks for drinking water, storage of dry food products by the type of flour or grain. Concrete, mineral substrates, aluminum and its alloys, as well as carbon and low alloy steels, can be applied surfaces. For a bucket (10 kg) you will have to pay 290 rubles. If it is necessary to purchase food varnish in large volumes, attention should be paid to containers up to 200 kg.
Features of urethane yacht varnish
Urethane yacht varnish is offered for sale in the form of urethane-alkyd and alkyd-urethane ship varieties that dry for a short time and have a smaller amount of 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 changes in temperature. This is practical if the cottage has a floor heating system. Urethane varnish, the characteristics of which are important to know before purchasing, can be alkyd-urethane ship, which can only be used when conducting outdoor work, as it is toxic.
Characteristics of the Ethereal varnish
Urethane lacquer “Eteral” is a solution of a urethane pseudo-prepolymer, cured by contact with atmospheric moisture. The main areas of application are the possibility of applying to concrete, metal, floor surface, as well as wood. The main advantages are durability, comprehensive protection and cost-effectiveness. With proper preparation of the base and application by technology, the varnish can be used for 30 years. At the same time, he will retain his technical and operational qualities. This urethane composition 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 ° C, which indicates unpretentiousness to conditions. After hardening, this composition can protect surfaces in the conditions of production workshops, as well as outdoors in the northern regions. The base is resistant to abrasion and allows for intense loads.
Features of the use of varnish "Eteral"
"Eteral" can be applied with a spray gun, roller or brush. In this case, the temperature should be equal to -20 to +40 ° , while air humidity can be equal to a figure in the range from 30 to 98%. When applied in a single layer per square meter, about 50 g of the composition will take. The number of layers can reach four.
After opening the container, the varnish can be used within 24 hours, these storage conditions should be adhered to. If it has not been used to the end, then the surface should be poured with a moisture diluent or toluene, the layer height of which can reach 2 cm. After that, the lid is tightly closed and the varnish is left in this state until the next use is necessary.
