Heat-resistant paints, metal: properties and classification of compounds

Many owners of country houses face the challenge of fireplaces, stoves and other objects made of metal. This type of material is vulnerable to moisture and other environmental factors, so the update of paint coating is not only directed at maintaining aesthetic appearance, but also to extend the operational timing of the most design.

Not every finishing material capable of withstanding high temperatures. Therefore, for the treatment furnace and fireplace designs, experts recommend to buy heat-resistant paint for metal.

Note!Usually, the composition can withstand the effect of temperature not exceeding 40-50 ° C. Constructions iron furnaces installed in a bath heated up to 600-800 ° C. In the combustion zone, this figure may reach almost 1,000 ° C. Professionals recommend to choose the composition according to the type of the furnace, because it affects the necessary degree of heat resistance. For example, brick walls of furnaces able to warm up to only 200 ° C.

Features and properties of heat-resistant paint on metal to 1000 degrees

Thermal stability of such dyes due to the presence of organosilicon components in their composition. In addition, the material contains fillers, pigments and polymers. Thanks to these components, colorant provides metal corrosion protection and environmental influences.

Polymers present in the composition, characterized by high strength. Typically, they are made based on oxygen, silicon and organic radicals. The list of components that provide thermal stability of the refractory metal ink for barbecue or furnace ends. High parameter stability due to aluminum powder.

The operational life of the majority of the heat-resistant dyes reaches 15 years. Method of application of the material and the amount of organic resin in its composition affects the elasticity and adhesive properties of the coating, while it is drying.

The advantages of heat-resistant paint for metal for ovens:

• electrical insulating properties - the material for finishing metal constructions, which can pass electricity;
• corrosion protection - heat-resistant paint prevents the destruction of the metal under the influence of moisture;
• resistance to the influence of aggressive environments - protected from the adverse effects of chemicals;
• ability to maintain the properties at high and low temperatures and sharp drops;
• plasticity - during heating expansion of metal is exposed, so decoration will stretch rather than covered cracks and crumble.

Classification of fireproof paint for metal

Heat-resistant dyes are classified according to various criteria. Most often, the compositions are divided according to the type of packaging. Consumers can purchase a heat-resistant paint for metal or for the furnace as a barbecue spray volume of 400-500 ml, banks (by weight of 1 kg), pail or drum. The volume of composition in the bucket can be varied in the range of 10-20 kg. Spaciousness barrels is 40 kg or more.

Note!Heat resistance during storage of the dye depends on the manufacturer and component. However, the minimum duration of any material is 7 months.

Materials also vary according to the method of application. Most often used for this purpose roller, brush or sprayer. The tool used for coloring the surface, consumption depends on the composition. For example, if applied to a heat-resistant enamel to metal using a brush, the material consumption is 20-40% greater than when using an atomizer. The resulting coating that is obtained by substantially the same in stability. Accompanied by increased consumption of the dye and the use of the aerosol deposition method.

Regardless of the application method should be selected carefully dye with high adhesive properties. In other words, the composition must be well secured to the metal surface. Only under this condition, the coating can provide a reliable protection against corrosion damage.

Field of application of heat-resistant paints for metal

Resistant dyes used for finishing products operated under conditions of strong humidity and high temperatures.

The possibility of such compounds useful for such objects:

• steam room;
• sauna;
• drying chambers (under these conditions recommended buy fire paint for metal capable of withstanding from 600 to 1000 ° C);
• a furnace;
• braziers.

Often resistant to the temperatures used for processing the compositions elements of heating systems. Enamels with similar properties and are widely used in the automotive industry. Especially for this purpose are available dyes for mufflers, brakes, engine components and other elements.

Preferably such dyes are used for the treatment of metal surfaces, although commercially available formulations can be found with the same properties for the treatment of brick, stone and wood.

Important!Before purchasing the paint be sure to familiarize yourself with the manufacturer's instructions and recommendations for the use of the composition on certain surfaces. If the assumed opening construction furnace in the bath, it is necessary to take care to not only finish showed resistance to temperature, but also withstand the influence of moisture.

Variety of heat-resistant paints, metal: the price and types of finishing materials in composition

The composition of the components is extremely important in the finishing materials. It depends on this degree of stability of the dye and the temperature condition in which it can be applied.

In view of the foregoing categories are the following compounds:

• alkyd;
• epoxy;
• colorants based on heat resistant glass and composite materials;
• ethyl silicate and epoksiefirnye (single component);
• silicone (monocomponent).

Alkyd or acrylic dyes - used for machining heating systems. They are able to withstand temperatures up to 100 ° C. This category includes materials with zinc-phosphate and zinc compounds. Price from 2500 to 5500 rubles.

Epoxy dyes can withstand the temperature not exceeding indicator 200 ° C. Some types of dyes do not require pre-paint primer on the metal surface. The average price of this category of pigments is in the range 2000-8000 rubles. depending on the manufacturer and the volume of the container.

The temperature limit and ethyl silicate epoksiefirnyh dye is 400 ° C. As part of these materials contain metal powders. The price range for these types of dyes covers 3200-9000 rubles. per pack. Such compositions are used to process and barbecue grills.

One-component silicone compositions to fully withstand the influence of temperature to 650 ° C. As a basis for the creation of such dyes manufacturers use silicone resin type polymer. Often in the material aluminum powder is added. The price of this paint ranges 300-6100 rubles.

Formulations of refractory glass and composite materials can withstand temperatures of from 650 to 1000 ° C. Price refractory paints, metal of this type - 2500-8000 rubles. per pack.

Which is better to buy a heat-resistant paint for metal: Select structure

To choose the optimal dye, it is necessary to take into account the basic criteria put forward by the materials of this type:

• the level of heat resistance;
• manufacturer recommended dyeing temperature;
• time to dry (no more than 3 days);
• Technical characteristics of the composition.

In trade there are dyes with different degrees of heat resistance - from 120 to 1000 ° C. This indicator is selected based on the conditions in which it will be operated. The highest heat is characterized by a metal furnace (800 ° C), the maximum limit of the radiators installed in apartments - 90 ° C.

Useful advice!If added in the heat-resistant paints, metal brazier for organic resin, it is possible to accelerate the drying time of the coating, as well as to enhance ductility and adhesion properties.

The quality of staining result depends on whether to support the requirements of application technology. Among these requirements concerns the pre-treatment, blending circuit material temperature regime to be followed during operation. Most experts recommend produce staining of metal surfaces at temperatures from -30 to 40 ° C. On this depends the subsequent operation and life of the coating.

What paint to paint the grill made of metal: heat-resistant, heat-resistant and fire-resistant formulations

Metal surfaces which are exposed to excessive heat during operation, are covered by refractory, heat-resistant or heat-resistant dyes. Heat-resistant finishes recommended for coating structures, which temperature does not rise higher than 600 ° C.

Possible to use these dyes for the processing of metal parts or brick furnace designs, completely made of this material, including barbecues. In this case, it is not necessary to apply the heat-resistant composition on the surface of the equipment installed in the bath. Most often, such a furnace heated to 800 ° C. Therefore it is better for these purposes to use heat-resistant dyes.

Fire-resistant finishes are designed for coloring of products, which are in close proximity or contact with an open flame. For barbecues and barbecue is the best option. The use of such dyes for treatment of other objects to be impractical and would entail undue costs.

For products that are heated less than 200ºC, it is best to buy a heat-resistant paint for metal in the can. High temperature dyeing compositions are applied to the elements and radiators in heating systems homes and buildings, parts of automobile engines and furnaces joints and masonry made from brick. For low temperature conditions are also suitable, heat-resistant varnishes, withstand heating 250-300ºC.

Note!Do not confuse the refractory compositions with flame-retardant dyes. A strong heating such materials can swell, blister and block the access of oxygen to the surface, preventing its destruction.

Guidelines for choosing the optimal heat-resistant paint for stoves

If you cover the metal furnace conventional dye coating very quickly turn black and become a source of smoke and unpleasant odors. Composition should match the type of surface on which it will be applied. Scope is always indicated by the manufacturer on the packaging. If the composition is intended for the treatment of a variety of materials, all of this information in a smaller font can be found at the bank. In the absence of such data, as well as the brand name should abandon the acquisition. Such questionable dyes may be of poor quality and harmful to health.

Significance and decorative qualities. Most often, the buyer has a choice between gray or black heat-resistant paint with silver metal. On sale there are other shades, although harder to find, for example, red, blue, white, green. Manufacturers offer dyes, with which you can create a matte or glossy finish. In this gloss may possess different degrees of gloss.

Features heat-resistant paint for the brake calipers and the muffler

Resistant dyes used for the treatment of vehicle parts made of metal. Wherein the coating has not only a decorative function.

Use of a heat-resistant paints for the muffler, drums, and supports other elements provides additional protection, but also improves the characteristics of the machine. In the major cities in the winter roads sprinkled with reagents, aimed at fighting against ice. These aggressive substances can cause corrosion of metal vehicle parts in contact with the snow or water.

Due to the increased heat transfer dye machine supports. The fact that these cells have a porous surface, which inevitably accumulates dirt. As a result, the cooling time is substantially increased. In addition, the assembly process difficult cleaning without removing the wheels. After processing the parts thermally stable dye on a surface of a smooth coating is formed which improves the thermal exchange that prevents accumulation of dirt. A cleaning process unit may be readily accomplished using a small trickle of water.

Dyes for processing metal parts of the car is available in three forms:

1. Spray (aerosol spray).
2. Bank.
3. Kit.

Useful advice!Should not completely remove the slides for staining. This will not only entail additional costs but also cause problems in the braking system.

Selecting colors for calipers and application technology

Despite the popularity of the heat-resistant paints, metal cans due to the low cost, you can not call this the best option finishes. In most cartridge 1 barely covers the surface of the drum 2. In addition, the technology requires a carefully close the other parts of the car that during the spraying should not stain.

The dye in the bank is a bit more expensive than aerosol cans. Such a mixture allows to obtain a pure and high quality coating with a brush. It does not require the removal of the brake system with discs. The disadvantages of the compositions in the bank include the long time it takes to staining.

Complete sets of heat-resistant dyes contain a complete set of tools designed for the full painting of metal parts of the car.

Typically, the kit includes the following components:

• balloon with a liquid for cleaning the surface;
• resistant dye;
• Primers composition;
• aids (a brush with stiff bristles, protective gloves).

The average dyeing process, together with the expectation, until the paint is dry, lasts about 2 hours.

The application of the dye in the following order:

1. Removable wheels.
2. Supports are cleaned of rust and dirt.
3. The dye is applied to calipers in two layers.

Before applying the second layer of material, it is necessary to wait at least 35 minutes. The most popular and sought-dyes in this segment: OMP, Kerry, Motip, Foliatec and Kudo.
