Assortment of varnishing of paints and varnishes today is very extensive. Each type of such a mixture has its own purpose and unique characteristics. So, epoxy enamel, the property and application of which will be considered below, enjoys the greatest demand among the other varieties of enamel paints.
Peculiarities
The main features and distinguishing features of epoxy enamel are:
- Identity of technical specifications with epoxy resins, because it is based on them and is manufactured by this paintwork.
- High waterproofing quality. Using the enamel of this species, you can forever forget about such a problem as poor-quality waterproofing of any surfaces.
- They are suitable for painting almost any surfaces, for example, made of wood, metal, concrete and even plastic.
The presence of such unique features and influenced the wide popularization of this paintwork.
Pros and cons
On high demand for enamel made on the basis of epoxy resin, Her advantages were greatly influenced:
- Epoxy paint coating creates reliable protection against various acids, gases and alkaline solutions, remaining in the form of a film on the painted surface.
- High level of adhesion provides reliable, uniform coating of working surfaces from any materials and a dense clutch with them.
- Epoxy enamel is not subject to negative impact of any kinds of solvents and other oil industry products. So it is widely used in the automotive industry.
- After staining with epoxy enamel, any surface becomes protected from rust, pathogenic fungi and bacteria, as well as negative water exposure.
- Epoxy enamel in most cases is allowed to be applied even in one layer. This will be enough for comprehensive product protection.
- Coloring of any surfaces of epoxy enamel makes it possible to significantly extend their service life.
This particular paintwork and its shortcomings have:
- There is a bad level of protection against the negative impact of ultraviolet rays.
- When staining the surfaces that are strongly heated, the paint quickly yellow.
- The average time of its drying is 24 hours.
- Requires a thorough cleaning of the working surface before using epoxy enamel.
- Be sure to comply with the temperature regime during operation.
- Emale-based epoxy resin must be used only in well-ventilated rooms.
The advantages of such a coating are still more than flaws, and the pros are more significant. Therefore, the popularity of such enamel is increasing every year.
Composition and properties
Today there are several types of epoxy enamels, each of which has unique properties:
- VDP R-270 – This is a two-component, protected from the effects of water compositions, the enamel of white. Can be used outside and indoors, suitable for staining of metal, concrete, plastered, wooden and drywall surfaces. Reliably protects from mold, water and corrosion. Has a high level of security, it is considered one of the most fireproof, resistant to fading. Dries off the coating in two hours, requires applying in two layers. Enamel is produced not only in white, but also in black, beige, gray, brown and blue.
- EP-1236 Designed specifically for surface treatment of their fiberglass, aluminum and metal. Refers to the category of fire hazardous tools, widely used in shipbuilding. Characterized by quick drying, minimal consumption, rather pronounced aroma. It can be applied in three ways: roller or brush, pneumatic sprayer or airless sprayer.
- EP-773 – This is an enamel specifically designed for staining metal surfaces, which will continue to contact with different alkalis at high temperatures. Average drying time – from two hours to days, the surface of the coating matte and smooth, the thickness of one layer is not more than 25 microns, the consumption of enamel minimal.
- EP-5116 – Black protective enamel, intended for staining of metal structures. Mass application got in the color of oil-estervoices and oil pipelines. It has a high level of anti-corrosion protection, so it is painted with those metal structures that are most often in contact with water. After drying, it turns into a dense, glossy film of black, differs in high drying rate.
- EP-140 – this is a wear-resistant epoxy enamel, which can only be used on previously primed surfaces. Suitable for staining concrete and metal structures, has a high level of fire safety. Characterized by small consumption, high drying speed. On sale enters various colors. Forms a dense film on the painted surface, which protects against rust, moisture, acids and high temperatures.
Each varieties of this paintwork can be used not only in industrial, but also in living conditions. It is very important when it is choosing and operating clearly follow the instructions and recommendations of the manufacturer.
Application
By making a decision on the use of epoxy enamel, it is necessary to choose its form depending on the material manufacturing material. Either a universal paint and varnish agent should be selected, or specialized, for example, for concrete or metal.
You can apply this means of various types as with a brush or roller, so using a special paintopult. A specific method of application must be chosen, based on the area of the working surface, the location of its location and the existing one hand tools.
Training
The use of epoxy enamel of any kind begins with the preparation of the working surface. First, it is necessary to remove the entire garbage from it and dirt, the remains of the past paintwork. If the surface is too fat, then it must be deguted.
The next stage of work is a priming. A particularly careful approach to the case requires the primer of concrete coatings. The concrete itself is quite porous, so the equalization of its surface should be given the greatest attention. The primer must be allowed to dry out before applying enamel on it.
Preparatory work includes the preparation of the most paint and varnish material. It must be mixed thoroughly to make sure in the homogeneity of its consistency.
If the manual for the manufacturer is indicated on the need for additional use of the solvent or hardener, then you need to choose these means of the same brand. Only so you can get a really high-quality epoxy enamel suitable for further use. In advance, it is necessary to take care that all the tools needed for work were at hand.
Methods of application
After performing all the preparatory work, you can proceed to direct staining of epoxy paint surfaces based on the dimensional resins.
The procedure can occur in a different way:
- Painting with a brush or roller – the simplest and affordable methods of application. But it should be remembered that when they choose, paint consumption will inevitably be great. From the store capacitance should be pulled out a small amount of thoroughly mixed enamel into the container of smaller volume or in a special roller tray.
Brush omitted into the remedy is worth not more than half, shaking the excess enamel into the container.
Roller needs to be evenly soaked with paint from all sides, but so that its surplus does not flush on the floor. Movements should be neat and slow, each new portion of enamels must be applied and in the same direction with the previous. Such a staining technique requires enamel of at least two layers.
- It can be applied epoxy enamel with a special paintopult or airless pulverizer. In this case, the liquid must be pouring into the tank and further use the device in accordance with its instructions.
It is very important with multi-layer enamel enamel to give the previous layer enough time to dry. The second and all subsequent layers are allowed to be applied 23 hours after applying the first, but no later than 24 hours.
Safety regulations
Epoxy enamel refers to the category of toxic means. It has a rather strong chemical smell, and when contacting the skin can cause burns and an allergic reaction.
It is very important during work to clearly comply with all security requirements:
- The room must be well ventilated.
- It is better to use a respirator or mask as an additional protection.
- It is necessary to choose the right clothes – it must completely close all parts of the body, should be put on special gloves.
- Only wooden blades should be used for mixing enamel.
- Store and use paint only under the conditions that are indicated by the manufacturer on the container.
Compliance with these simple, but very important rules will allow quality to paint any surface and protect them from various negative impacts for a long time.
