Heat-resistant paints for metal up to 1000 degrees: a dozen leading heat-resistant products

Advantages of thermal paint

The properties of high-temperature paint allow it to be used where other materials simply will not work. It is versatile and can be used anywhere.Its benefits include:

Electrical insulation. Required where there is a possibility of contact with electric current.
Adhesion strength. Perfectly lays down on the painted surface.
Corrosion protection. The paint can be used in rooms with high humidity.
Resistant to sudden temperature changes. Withstands not only high but also low temperatures.

Resists most household chemicals.
Plastic. When heated, it does not crack, but expands along with the metal, stretches.
Low toxicity

This is important when working indoors.
Ease of use. Can be applied in any convenient way.

All these qualities make it attractive to use.

Paint composition

First, let's look at the composition of heat-resistant solutions. It is different, and is selected based on the operating conditions of the painted devices. That is, the main composition depends on the height of the temperatures to which the materials will be subjected.

Composition - base:

1. Acrylic and alkyd resins. Operating temperature maximum - up to +100 degrees. Are applied to metal designs of domestic use. A zinc-phosphate mixture can be added to the coloring enamel. Compatible with epoxy primer.
2. Epoxy resins. Temperature maximum - up to +200 degrees.
3. Ethyl silicate and epoxy resins. Enamel with such a base is used at temperatures up to +400 degrees. The admixture of metal powder is allowed.
4. Silicone resins - paint heat resistance - up to +650 degrees.
5. Composition with composites and heat-resistant glass - up to 1000 degrees of heating.

Additional substances give and enhance other protective properties of the coating.The composition also includes solvents, pigments, silicon organic varnishes and more.

Again, the ability to apply on various types of metal surfaces also depends on the quality of the mixture. Let's try to make this DIY enamel.

How to choose

To choose the right paint for the stove, you need to carefully consider the label, where they write what surface it can be used for, for example, heat-resistant paint for metal products. Often this information is printed in large print - it is difficult not to notice it. In cases where the scope of paint and varnish products is wide, this is also written on the packaging, but in small print. Be that as it may, such information must be indicated on the packaging, as well as the name of the manufacturer. If these data are not available, you do not need to purchase such a product. It is possible that this is a counterfeit product that may threaten your health.

For metal sauna stoves, use only moisture-resistant compounds, otherwise they will not last long on the surface.

What are there?

Metal is actively used in all spheres and industries. Depending on the type of activity, specific formulations have been developed. It is customary to classify anti-corrosion compounds according to one element:

Alkyd

Budget option, in high demand. Alkyd enamel is made on the basis of the varnish of the same name, or synthetic resins. The main field of application is the painting of galvanized metal surfaces.

Dignity:

• does not require much time to dry;
• operation for many years;
• aggressive chemicals and temperature changes do not harm;
• easy to use and low consumption.

Flaws:

5 Application features

It shows its qualities most effectively at a temperature of -10 ° C. However, it should be remembered that the coating will dry for a long time and if a second layer is provided, then it must be applied after 2-3 days (according to the instructions).

Despite the fact that the paint itself does not freeze, however, at sub-zero temperatures it becomes viscous. Therefore, in order not to slow down the process, it is recommended to use two containers of paint alternately, one of which will be warm.Otherwise, it will have to be heated in a container with warm water.

The packaging must indicate the storage temperature of paintwork materials. According to the standard, it is necessary to store materials for priming and painting from -40C to +40C.

Training

Processing and painting metal in frost requires more careful preparation. The surface must be well cleaned of dirt and rust, using special brushes and abrasive compounds. Acetone and isopropanol are used for degreasing. You can paint only if the surface is dry. In the case of frost coverage, the area must be treated with a flash of a gas burner.

Tool selection

Paint with brush or roller. In frosty weather, the nozzle of the spray gun will quickly become clogged, so it should not be used.

Purpose

Heat-resistant paints are able to transform the product into any color. Compositions intended for painting furnaces have an excellent level of protection against corrosion, do not collapse under the influence of moisture. Mandatory requirements for this group of paints are reliable protection against electric shock and the ability to tolerate contact with aggressive substances.

All the desired properties of the coating must be maintained both at significant heating and at low temperatures, even if the drops are very sharp. Additionally, such a valuable parameter as plasticity should be mentioned - the decorative layer should stretch after the heating base, and not split. The absence of the necessary properties also guarantees the appearance of cracks after drying.

Heat Resistant Metalwork Paints can be applied to any type of ferrous metal or alloy. The existing classification subdivides coloring materials according to various criteria. First of all, the packaging method.Cans, cans, buckets and barrels are used as containers. Another gradation is made by staining methods, which determine the amount of paint used.

In everyday life, heat-resistant coloring compositions are applied to metal structures in baths, saunas, and to chambers for drying wood. They cover stoves and barbecues, fireplaces, radiators, mufflers and car brakes.

The best paints for rust 3 in 1

The presence of the prefix "3 in 1" indicates that the product works in several directions - priming, converting rust and decorating. Products of this type are resistant to any impact. After analyzing the reviews of consumers and experts, among the many products, two nominees with the best recommendations were selected.

Novbytchim primer-enamel

Paint "Novbytchim primer-enamel" is intended for painting any types of surfaces. It is applicable to both new and already partially or completely corroded products. The composition of the product is synthetic resins, additives, solvents (organic) and anti-corrosion components. The product combines the qualities of an anti-corrosion primer, a rust converter and a top coat. Its consumption is quite small - up to 120 ml per m² with a single layer application.

Work can be started at an air temperature of -10°C. The coating is preliminarily cleaned from existing delaminations. If it was painted with oil or alkyd compounds, then stripping to a matte state is necessary. A brush and roller are suitable for applying the composition. The paint also lays down well when applied pneumatically. For best results, apply 2 layers. Intermediate drying should last at least 60 minutes. Complete drying takes only 2 hours.

Advantages

• Fast drying;
• Resistance to different types of exposure and temperature extremes;
• High adhesion rates;
• Excellent decorative properties;
• Good hiding power.

Flaws

Not suitable for heated surfaces due to odor.

metallista

The rusty metal paint in question, from the myrrh brand Tikkurila, provides a 3-in-1 effect. Thanks to the wax included in it, it creates an increased protection of the metal from the negative effects of moisture, giving it excellent water-repellent properties. Structures coated with composition will last at least a decade without renewal. Metallista is immune to the effects of fats, lubricants, industrial alcohols and turpentine, so its scope is unusually extensive.

The manufacturer offers several base shades for tinting, but in total they can be created up to 32 thousand. The hardened layer easily withstands heating up to 80 ° C while maintaining the original color. Drying of the applied composition to sticking takes up to 2 hours. Metallista must be topped up with solvent before use. It adheres well to uncleaned surfaces without prior application of primer.

Advantages

• Creation of an insoluble base;
• Delay the formation of corrosion;
• Eliminates the need for preliminary preparation of the base;
• Double chemical formula;
• Ease of use with any tool.

Flaws

• Implementation of small volumes;
• The need for tinting;
• Not a very large number of finished colors (four).

Enamel is sold in small containers - from 400 ml to 2.5 liters.

Rules for selection and use

To choose the right paint, you need to determine the maximum temperature of the surface on which it will be applied. You also need to calculate the area and make a choice between a spray in a can and a liquid consistency in a jar. But there are some more rules to be aware of.

Specific nuances in terminology

Many sellers in their advertising campaigns are very frivolous about the terminology adopted for compounds that can be applied to surfaces with high temperatures. There is no normatively established gradation according to the name of the composition and its maximum allowable heating temperature.

However, three established terms are commonly used:

• high temperature;
• heat-resistant;
• heat-resistant.

High-temperature paints for metal include compositions that can withstand prolonged surface heating up to 2000C. They are used to process radiators and heating pipes, brick ovens and fireplaces. In addition, they will be suitable for automotive parts such as engine, muffler and exhaust system.

Water jacket of a metal furnace. Outside, it does not heat up above the coolant temperature, therefore, high-temperature paint can be used to treat its surface.

Heat-resistant compositions are used for surfaces with temperatures up to 6500C.

Such paints are used for the following metal objects:

• sidewalls and bottom of furnaces;
• barbecues;
• pipes for the removal of combustion products;
• the junction of the pipes of the water circuit to the furnace or boiler.

Heat-resistant paints and enamels often contain pigments that give them color, so they can be used to create original interior design solutions.

Heat-resistant paint is designed to cover surfaces that are heated to temperatures above 6500C. First of all, these are cooking stoves and furnace fireboxes, as well as grates for wood-burning stoves and fireplaces.

Some types of thermal paint have an additional feature - fire resistance. This means that the painted surface may be in direct contact with the flame. From household metal objects, this is true for the fireplace grate and the inside of the barbecue.

Theory and practice of thermal hardening

Heat-resistant paint is inherently heat-resistant enamel. To create an impenetrable barrier, you must perform thermal hardening process. In the process of heating the surface with the composition applied to it, the layers polymerize, after which the access of air to the dyed metal stops.

Sometimes a colorless varnish is applied to protect metal products. This type of coating also requires thermal hardening.

It is after thermal hardening that neither oxygen, which causes the rusting process, nor moisture can penetrate under the enamel. Prior to this, the paint has only a decorative and, in part, protective function from physical impact.

Moreover, after creating an impermeable layer, the evaporation of the substances contained in the paint into the room air stops. Therefore, ideally, you should wait for the specified period of complete drying, which is indicated on the label or in the instructions, and then immediately carry out the thermal hardening procedure.

Typically, the temperature at which enamel polymerizes is 200-2500C. This leads to one common mistake that is often made by people who have residue after painting the stove.

It is impossible to apply a heat-resistant composition that requires thermal hardening to radiators and heating pipes, since the degree of their heating is insufficient to complete the process. For slightly hot objects, you need to use ordinary high-temperature paint.

Theoretically, the heat hardening process should take place at a constant temperature for 30-60 minutes. However, in practice, such “laboratory” conditions are unrealistic to achieve.

Therefore, wood-burning stoves, barbecues and fireplaces are not flooded at full capacity and gradually increase their heating. Typically, a test run takes 1.5-2 hours. Another option is warming up with an industrial hair dryer.

Features of the choice of paint for the oven

You cannot paint a stove with simple paints: the highest temperatures that they can withstand are 45-55 ° C. During the first fire, this coating will swell, begin to change color before our eyes, go in bubbles, and also spread “aromas” and smoke. Therefore, special formulations that can withstand elevated temperatures are clearly needed.

The degree of heat resistance required will depend on the type of furnace. If this is a metal furnace, then it can heat up more than 700-900 ° C: the temperature is higher in the combustion zone, but taking into account the design, the outer walls may not heat up so much. For the outer surface of the brick, increased performance is not required - 300 ° C is enough.

An important requirement is that the refractory paint for metal for the furnace must be suitable for interior painting. For sauna stoves, it is best that it still protects from high humidity.

Thermal paint terminology for metal

For painting surfaces with elevated temperatures, refractory, heat-resistant and heat-resistant paints are suitable. Do not use flame retardants. Although the name is similar, the purpose of this paint is completely different: when heated to a certain temperature (about 150 ° C), it bubbles, blocking the access of oxygen to the structure, thus preventing its destruction. Pretty useful effect, but not in the case of the stove.

1. Heat-resistant paints, as a rule, have an area of ​​application up to 700 degrees. These compositions can be used to paint metal elements of fireplaces and brick stoves, metal heating stoves. It is undesirable to cover the body of metal sauna stoves with these paints, since in some places the temperature rises to 900 ° C. For them, there are heat-resistant enamels that can withstand temperatures up to 1000 degrees.
2. Fireproof paint for metal can withstand open fire. Their operating temperature is even higher, however, for domestic use, these compositions are unprofitable, as they are quite expensive.
3. There are also high-temperature paints that are used to paint the radiators of the heating system. As a rule, they behave normally if they are heated no more than 250 ° C. They can only be used for brick ovens - they are perfect for tinting the surface or painting the seams.
4. There are also heat-resistant varnishes. They normally tolerate temperatures up to 300−350°C. If a brick is treated with such a varnish, the surface will become brighter, acquire color and shine.

Application for different surfaces

In order to decide which paint to paint the oven with, you need to pay attention to which surfaces this composition is intended for. Often the scope is indicated on the packaging in large letters.

For example, refractory paint for metal. If the scope of use is extensive, then it is indicated in smaller print, but it must be on the packaging, like the brand name. If these data are missing, refuse the purchase. Most likely, this is a fake, and the combination of high temperatures and questionable quality is dangerous to health.

Paint for a metal sauna stove, in addition to temperature resistance, must protect against high humidity. This way it will last longer.

Color selection

Heat-resistant paint, as a rule, is found in silver, gray and black. Other shades need to be looked for, but they also exist: red, white, blue and green. The finish is glossy or matte.

Matte black thermal paint is usually found, however, some manufacturers have different shades and colors.

Manufacturing form

Thermal paints are made in cans or cans. Accordingly, it can be applied from cans with rollers, brushes or sprayed using special equipment, and sprayed from cans.

Heat-resistant spray paint, as a rule, has a volume of approximately 500 ml. In banks, packing is usually 0.4-5 kg. There is a larger packaging in barrels and buckets.

What is more convenient? It's a matter of habit. With dexterity from the can, the layer comes out more uniform. In this case, there may be less consumption than when using a brush or roller.
