Heat-resistant enamel: types and nuances of choice

 Heat-resistant enamel: types and nuances of choice

There are cases when you have to work with non-standard surfaces. They may be hot or heat up quickly. For such works can not use the usual paint. The best solution is heat resistant enamel.

What it is?

Heat-resistant enamel is very different from other types of paints and their components. The composition of heat-resistant paints includes silicone lacquer, and it already has pigment compositions. Because of this, they can be not only black and white, but also other shades that can fit any metal.Special fillers expand the range with different tones for non-ferrous metals, for example, for painting steel and cast iron.

Enamel gives the surface strength and durability, it is important to cover the lids or fasteners. With constant abrupt changes in temperature, the base should not change its shape.

Also, one of the main functions of heat-resistant enamels is thermal protection of surfaces that have already been painted. All this is due to the aluminum powder that is part of the paint. It works as a kind of reflector, which prevents thermal radiation from penetrating. Tanks with gas of liquefied type, also covers of metallic type, gas pipelines and similar structures and parts are treated with similar compositions. Such a simple black heat-resistant enamel can withstand temperatures of six hundred degrees Celsius.

Special features

Heat-resistant enamel has its own unique features:

  • additional type of insulation;
  • anti-corrosion properties;
  • good chemical resistance;
  • good ductility.

The main feature of heat-resistant paint is the exposure of different temperatures, while it does not change color and can “work” with any type of surface, this is its main technical characteristic.

Extra insulation is very important, especially when it comes to metal surfaces. Thanks to the enamel, no static electricity is connected, and friction between the surfaces does not occur. That is, the paint will not lose its plasticity under any physical, chemical and electrical influences.

Enamel, which is used for elevated temperatures, has excellent protective properties against the appearance of rust.

Heat-resistant enamel is good to use also for rooms where works with various components will be carried out. After complete drying, the paint will not be subject to any changes. Enamel perfectly tolerates various temperatures, does not change its shape due to its plasticity, and does not burst.

Advantages and disadvantages

pros

  • The main advantages of heat-resistant enamels are comfortable and convenient processes of painting any surfaces and a high percentage of protection against various external and internal indicators.
  • Quick surface preparation for possible further work. Sometimes there are cases when it is necessary to remove the old coating on the surface, and under it find loose rust that needs to be removed.This is done using a mechanical tool, and because of what traces remain, and as a result - irregularities. And then you need to turn to these types of work to remove the areas of corrosion that was previously.

With the help of enamel in this there will be no need. She will be able to smooth all corners and at the same time smoothly paint.

  • Excellent protective properties when applied. It is enamel that is the component that includes high-quality, quick-drying alkyd-urethane varnishes that can quickly dry. Because of them, the coating becomes much stronger, more resistant to rapid erasure, external and internal factors.
  • There are other positives that make heat-resistant enamel the best choice for working with heavy surfaces. The life of this product is 5 years.

Minuses

Among the shortcomings sometimes distinguish such a feature as pricing. Among all the brands, enamel is sometimes found to be high prices, but still, thanks to a rather large assortment, you can choose a good brand at the best price.

Kinds

All the paints that today are used to paint surfaces that can withstand high temperatures, divided into three groups.

  • by packing methods;
  • shelf life;
  • and application methods.

The choice of heat-resistant enamel depends on the purpose for which you acquire it.and what surface you will cover. Today, there are even aerosol samples for painting. The capacity of these cartridges is 0, 5 liters. If you need to purchase a larger volume, it is best to take samples that are sold in cans, buckets or in barrels of 40 kg. To paint one square meter, you need about 230-260 grams of paint.

For seven months (the smallest shelf life) from the date of production, the paint retains all its properties. According to the standard, manufacturers must indicate on the product packaging the final date of sale. Aerosol type paints are suitable for the easiest application, in such a situation it will not be necessary to acquire any additional tools, but this option is not suitable for painting a large area.

For painting large areas, it will be more economical to buy cans and apply enamel with a brush or roller, only a roller should be chosen with an average length.

If the paint has a good fluid consistency, then it is possible to paint using a pneumatic sprayer that works with the compressor.This type of staining is suitable for plates, you can also use spray staining with a can.

Regardless of the method of application, stability and quality is fully maintained. Also, it is necessary to understand that when using an aerosol or spray gun the consumption per square meter will be slightly higher than when working with a roller.

Kinds

  • Nerzhamet-aerosol - it is an anticorrosion paint, sold in cans for painting metal surfaces. Such alkyd enamel consists of high-quality components that dry quickly, and therefore are excellent for building and various decorative works, for domestic use.

In addition, you can use it to paint scratches, chips and metal tiles. Similar paint is used for painting inaccessible places. On the surface, the paint looks glossy with a slight metallic luster. Good for all types of work, even for a gas stove.

  • Enamel KO - 8104 - used for painting asbestos-cement surfaces, which consist of metal and concrete. It can be used both for interior work and for an open area (on the street).This type of paint is excellent for corrosion protection of tanks, pipelines, chimneys and other equipment. An analogue of such a paint - brand 8101. In addition, you can use analogues such as 811,814,8111 of thermals.
  • Anti-corrosive enamel needed to protect against corrosion and paint decorative parts, they can be clean, and already painted, and even covered with rust. This type of enamel is excellent for any surface: steel, cast iron and various non-ferrous metals. It can be fences, gates, structures of construction type, equipment for the village, metal cabinets, windows, doors, wood. You can use target.

Packing and colors

Packaging may be different, everything will depend Which type of paint will you choose?

  • spray - 0, 5 liters;
  • can - from 5 liters;
  • bucket - from 10 -15 and up to 40 liters.

The composition of the paint will determine at what temperature it can be used. The main component that is in any paint composition is silicone lacquer.

Other types are also highlighted:

  • epoxy group;
  • alkyd group;
  • ethyl silicate and epoxy ether;
  • silicone;
  • paint using composites.

The colors are mainly black and white, there are collections where there is a large selection of different shades.

How to choose?

First you need to understand what kind of enamel is needed.

By temperature, they are divided into three groups:

  • heat resistant;
  • heat resistant;
  • fireproof.

Fire-resistant and fire-resistant paints are two completely different compositions. The main purpose of resistant paints is to make a fixed type of film that can cut off the access of air.

The paints that can withstand high temperatures include those that retain their appearance at a rate of 600 degrees Celsius. Similar products can be used for painting stoves, bath houses or machine parts. If the temperature is heated to 800 degrees Celsius, then it is necessary to choose paint from the group of heat-resistant. This is also a good choice for a rusty surface.

Paint refractory type is necessary for surfaces that are close to the fire. They can perfectly protect the surface from external factors. But it is necessary to understand that such paint costs a lot of money, and often already large companies acquire it for their work.

To save a little finance, you can purchase high-temperature paints. They are great for any working conditions where the temperature is no more than two hundred degrees Celsius. This paint is still covered with brick seams on the furnaces.
