Polyurethane enamels: characteristics and application

Perhaps the simplest kind of repair work can be considered the coloring of any surface, because even a person who does not have relevant experience in such works, let alone specialists, can cope with this. However, such manipulations involve the need to observe a variety of nuances. This includes the choice of paint.

After purchasing the product, you should familiarize yourself with the technique of applying the mixture and its characteristics. Only in this way will it be possible to create a durable coating that will be resistant to negative impacts and durability.

General description and purpose of polyurethane enamels

In the market of building materials among other paints you can find polyurethane enamels, which contain a huge number of additives that provide a high adhesion to any surfaces. Most often they have one component, which attracts users, because before starting the work, you do not have to mix the ingredients, because the paint is ready for use. Even if the application is carried out on a slightly moistened base, the mixture will firmly adhere to almost any surface and form an elastic film that will exhibit resistance to a variety of effects.

Polyurethane enamels are highly resistant to acid and alkaline effects, they are not afraid of water and temperature changes. Thanks to these characteristics, the paint is actively used for concrete floors in industrial premises, namely:

• Warehouses;
• Production workshops;
• Garages.

Among other things, such enamels are used in public premises, where the flooring is subjected to increased stress. They can have a specific purpose depending on the composition, so before acquiring it is necessary to familiarize yourself with the characteristics of the mixture.

Description and application of "Elakor-PU Enamel-60"

This mixture is a one-component colored moisture-curing glossy enamel, which can be applied even at negative temperatures. After the polymerization phase is completed, the surface acquires the quality of wear resistance and the ability to undergo the effects of chemicals. With this mixture it is possible to protect the concrete surface, for example, floors, ceilings, structures and walls.

Such polyurethane enamels are designed for indoor and under-canopy use, while in the open air their use is limited. In the latter case, it is necessary to waterproof concrete from groundwater. Before use, the surface should be cleaned and primed. Capillary-porous mineral surfaces, sand-cement screed, mosaic concrete, mosaic tiles, bricks, magnesian concrete can make the base. Excellent this polyurethane enamel for wood. It can be applied to plywood, wood or parquet.

The main advantages of Elakor-PU Enamel-60

If we consider such polyurethane enamels as those described above, we should highlight certain advantages, among them:

• Possibility of application at negative temperature;
• Purpose for hardening concrete bases;
• Short drying;
• Possibility of operation within 24 hours.

Even concrete bases of M-100 or less can be hardened. Polyurethane enamel 60 can be applied in several layers, between which it is necessary to wait for about 3-6 hours. This greatly shortens the time of work. After three days, the surface can be subjected to a full mechanical load. The composition described is single-component. This speaks for simple technology and inexpensive equipment for manufacturing, which reduces the cost of the material.

Features of application of "Elakor-PU Enamel-60"

The above-described polyurethane floor enamel can be applied to putty substrates, as well as dolomite, marble or quartz. The maximum application temperature is + 25 ° C, the material temperature can be equal to the limit from +10 to + 25 °. Humidity of air should not be more than 80%, and the surface temperature above the dew point should be greater by 3 degrees.

Before application, the enamel is well mixed until a uniform consistency and color are obtained. To do this, you can use a mixer for paints, which are set at 400-600 rpm. Use in work can be a brush or roller, as well as a method of airless application. In the first two cases, the material must be resistant to solvents. If one layer is applied, approximately 120-170 g / m ² will leave, which will depend on the initial smoothness of the roughing surface. To form a paint coating, it is necessary to apply the enamel in two layers.

Features of the enamel "Politon-Ur"

Polyurethane enamel "Politon-Ur" is intended for protection of concrete, ferro-concrete and metal surfaces from corrosion. Designs can be used in water, oil products and the atmosphere. The composition can be applied all-season when the temperature is between -15 and + 40 °.

Enamel has high decorative qualities, as well as resistance to oil products and water. It is perfectly suited for the protection of transport construction facilities in the chemical and oil and gas industries, as well as in metallurgy.

Additional characteristics of "Politon-Ur"

Polyurethane enamels of the type described above are used in complex coating systems where they play a protective and decorative role. The compositions are characterized by high strength and elasticity, resistance to ultraviolet radiation. Can be used in the factory and when painting structures on construction sites. Before using the enamel, it is not necessary to mix the components, which greatly simplifies the preparation of the material.

Properties and description of polyurethane enamel PROCOAT AP 259 SC

Acrylic-polyurethane enamel PROCOAT AP 259 SC is a two-component composition characterized by high adhesion with aluminum and non-ferrous metals, polycarbonate, stainless and galvanized steel. This enamel is preferably used as a single-layer self-priming coating. It has active anti-corrosive pigments, and also gives the surface resistance to ultraviolet radiation.

Primer-enamel polyurethane two-component is highly resistant to mechanical and chemical influences, as well as fading and temperature changes. This composition is an industrial high-tech alternative to multi-layer systems from finishing enamels and a variety of soils. It is very easy to apply the mixture even on large surfaces, since it has optimum spreading and absorbing swamping. The material can be applied to a large thickness with a minimum number of layers, no streaks are formed, and productivity is increased.

Conclusion

It is noteworthy that polyurethane enamels can create on the surface not only a highly decorative, but also a protective coating that can protect structures and bases from various negative effects such as corrosion, ultraviolet radiation, etc.
