Types of epoxy paints and their properties Epoxy paint: features of application, characteristics and composition

planned. And if we are talking about choosing a high-quality coloring composition, then the best will be the one that will always beautifully lay down on the surface, and most importantly, you need to maintain a fresh appearance. Now the choice of all kinds of dyes is very wide, and epoxy paints will take a certain place in it.

What is this? The base of epoxy paint and varnish material is resin, and almost all people are interested in what the epoxy itself is. As it turned out, translated from Greek.

language this word means "sour". In other words, epoxy coloring compositions can be called an oxidizing agent.

Properties and characteristics

Epoxy is the ideal option if you need a really high-strength coating that can withstand all aggressive influences, even chemical ones. This was proved by a very large scope of use of this type of dyes - for finishing outside in places with terrible climate conditions, for all kinds of equipment using high temperatures. Naturally, if you treat the floor with such a paint and varnish material, it will be able to last much longer than after processing with other types of coloring compounds, and the walls will withstand the influence of extremely caustic detergents.

This color is best suited for painting concrete, metal and many other types of substrates. In other words, the formulations alone can easily handle an entire room. This greatly simplifies the workflow, because then you do not need to purchase different compositions, and thereby stretch the work for a long time - epoxy products ideally fit on all types of substrates. Moreover, it also has the following advantages:

  1. The epoxy type of dye is quite resistant to chemical aggression, and it will not turn yellow after a while, but before applying it, it is imperative to prepare the base - degrease, clean and dry.
  2. Types of epoxy paints and their properties This type of paint and varnish composition has an incredible property - it is very resistant to atmospheric influences, and this will mean that it can boldly cover surfaces that are in open space, walls, roofs, and it is also possible to process metal joints.

  3. Most people believe that the main advantage is that it can be used to paint wet, fresh concrete. When performing construction work, which is important to do on time, such an advantage will come in handy.
  4. The coloring composition has electrical insulating properties. as well as a high level of thermal stability and fire resistance.
  5. Epoxies are waterproof and can therefore be applied to bathrooms and other types of damp environments.

  6. Epoxies are capable of self-healing (under a huge load, its film may begin to sag, but after it will return to its original position).
  7. In addition to everything that has been said earlier, epoxy will prevent bacteria from multiplying, and is also able to ideally protect surfaces from corrosion, and wood surfaces from decay. The pigment should not get into the surface of the insect pests.

But keep in mind that this paint has certain disadvantages:

  • Epoxy paints and varnishes are very resistant, and it also retains the brightness of its colors even after being exposed to an aggressive environment , but at the same time this is the main disadvantage. The point is also that if you need to replace the surface colors with a different one, it will be difficult to do with this property.

  • This dye has many advantages, which means that this will affect its price - it is very high.
  • There is another interesting point that relates specifically to powder paints. When using this type of coloring composition, you need to be prepared for the fact that it may even turn yellow when excessively heated.

Now let's consider what exactly this paint and varnish material consists of.

Details

Composition of epoxy paint

As mentioned earlier, such paint contains resin, and it is for this reason that the paintwork material is very durable.

But there are other components that must fully meet all GOSTs:

  1. Pigments - they are important in order to achieve the desired color or shade.
  2. Thinner - such a component is required for an ideal and faster connection, as well as dissolution of the remaining constituent elements.
  3. Fiberglass - This component helps improve thermal stability.
  4. Hardener - due to these components, the dye will dry much faster.
  5. Binding components - they will help improve the viscosity of paintwork materials.

What varieties are there?

Varieties

Epoxy paints can be divided into several types:

  • Powder.
  • Aerosol.
  • Two-component.

Types of epoxy paints and their properties The last type of paint and varnish material is considered the most popular in use. In addition to industrial-scale enterprises, it is often used even for home conditions.

It is made of a couple of components, and it is important to mix everything thoroughly before starting work. Aerosol is considered the most resistant type, and corrosion is scary. She can also easily endure the influence of an aggressive environment, even atmospheric phenomena. This paint and varnish composition has a distinctive feature - it can be cleaned independently. All types of substrates will be much scratch resistant after aerosol treatment, and it also gives surfaces a beautiful sheen from gloss.

Powder compositions are still mostly used in the industrial field, since it has very high quality indicators. At home, it is used very rarely, since heating chambers are important for the hardening of the coating. Such dyes can be divided into several subtypes:

  1. Polyester - such paintwork materials have the maximum level of resistance to wear. In addition, they will better protect surfaces from friction.
  2. Epoxy-polyester - such compositions for painting have a fairly low cost, while low qualities of resistance to abrasion, but they are very resistant to ultraviolet radiation and high temperatures.

Now about the use.

Scope

Epoxy can be called the following types of bases:

  • Plaster.
  • Plastic.
  • Baths, tiles and ceramics.
  • Metal.

  • Concrete.

We suggest considering certain areas of use. Epoxy paints are some of the best materials for painting concrete surfaces. Concrete is a very solid and reliable base, but without the necessary processing it will look terrible. In addition, it is completely unstable to some external influences, such as chemicals, moisture, etc.

Epoxy paints for concrete floors are made of two components, and prior to application, it is required to dilute the constituent elements in a certain proportion. After everything hardens, the paintwork material will leave a very strong film on the surface, and it will also ideally protect the screed from external factors, remove surface flaws, and at the same time give it a decorative and unusually beautiful appearance.

Epoxy contains a two-component anticorrosive enamel and is therefore an ideal variation for reinforced concrete and metal structures. The paint will create an impact-resistant thick layer that is resistant to chemical threats. It is quite possible to paint surfaces that are not prepared with it, as well as corrosion without the primary process of applying a primer.

Most often, masters recommend using epoxy coloring compounds to cover the bathtub and ceramic tiles, because the composition creates a high-strength coating. In addition, the paint is waterproof - the enamel will adhere perfectly to the base and protect against moisture levels. It dries out very quickly. And yet, before painting, it is required to carefully prime the surface to be painted.

If you need to paint plastic, for example, carbon fiber or fiberglass, it is still recommended to use such paints and varnishes on such bases, because they have excellent adhesive qualities.

The dye can be used as a primary material for most types of plastics, but it must be taken into account that the epoxy layer is not elastic at all, and the plasticizer cannot be used with it. Epoxy paint application is convenient for plastered surfaces.Their advantage is that they can handle wall surfaces without careful preparation. They ideally protect the surface, perfectly fixing the plaster layer. Moreover, it is important to take into account again the fact that the paint and varnish composition dries quickly, and 3-4 hours are enough for it, but nevertheless, ideal drying will not come earlier than a week later.

How to make a choice?

In order to correctly choose epoxy paints and varnishes, it is important to consider certain points:

  1. On what kind of surface the paint will be applied - for example, if you need to paint reinforced concrete or metal structures, epoxy paint in the form of an aerosol will be much better suited than the same powder paint, because it has high resistance to corrosion.
  2. Where the surface will be placed - in other words, do not forget about the effects of the environment and atmospheric phenomena. You will not use powder paints at home if you do not have heating chambers, and instead you will be able to safely use two-component formulations.
  3. It is also important to determine what stresses the treated surface will be subjected to. For example, walls, ceilings and floors in rooms such as garages, boiler rooms, workshops are usually prone to severe damage and exposure to chemicals.

  4. You need to calculate the coverage area so that you can immediately buy the right amount of paint.

Now about the use.

Application Rules

If you have correctly calculated the coverage area, then you can choose the ideal tools for high quality work. If the surface area is very large, then a roller will be the best tool for work. Through it, you can evenly apply paints and varnishes without drips, and for surfaces with a small area and coloring small-sized elements, it is better to use a brush.

When applying epoxy paint, certain rules must be followed in order for the work to be of high quality:

  • It is important to degrease the surface before applying the epoxy paint. Remove traces of oil and grease from it, and cleaning the surface is required with a solvent or detergent.
  • Surface should be sanded. If the surface is small, you can do everything by hand with sandpaper, and on huge surfaces you will need special sanders.
  • The bottom layer can be sprinkled with fine sand, and after the layer has hardened, it is important to remove the excess sand, and then apply a new one.

Most of the paints and varnishes, including epoxy ones, can cause skin burns, allergies, and also make breathing difficult. For this reason, it is required to observe the following safety rules when working:

  1. In no case should you use dishes that are intended for eating when working with paintwork material.
  2. Gloves and specialized clothing are required to handle epoxy-type paints. It is important to wear goggles and a respirator when sanding a surface that has hardened.
  3. Store epoxy paints and varnishes only in a closed container, and the storage temperature should not exceed +45 degrees, and the shelf life should not exceed 1 year.

  4. If suddenly epoxy-type paint gets on the skin, you need to immediately wash it off with cool water and soap or wipe the paintwork spots with denatured alcohol.
  5. Working with such compounds is required in a ventilated room.
