Heat-resistant paints: advantages and scope

In some cases, it is necessary not only to change the color of any object of the interior, equipment or construction object, but also that its decor has a certain degree of resistance to external influences, or rather, to elevated temperatures. Such a problem more often occurs when painting ovens, gas equipment, mangals, heating radiators, transformers, and t. NS. For these purposes, special paintworks have been developed that maintain high temperature and prevent the destruction of materials. They are called heat-resistant.

No need to be confused with flame retardant and flame paints. The heat-resistant or fire-resistant paint is withstanding the elevated temperature, the flame retardant prevents the combustion process, fire-proof – protects wood from burning and natural factors (rotting, fungus, insects).

Features and advantages

Heat-resistant paints and varnishes are made on a silicone-based basis with the addition of special fillers to increase the heat resistance and a spike. When applied to such a paint to the surface, it creates durable, but at the same time an elastic coating that protects against high temperature action.

The properties of heat resistance is achieved at the expense of the following properties that are part of the paint of components:

  • Good resistance to the temperatures of the base consisting of silicon, oxygen and organications;
  • High elasticity and good adhesion of fast-organic resins;
  • The abilities of the aluminum powder withstand the effect of heat up to 600 degrees.

The term of the heat-resistant paintwork is about fifteen years. The degree of strength, adhesion, elasticity and duration of drying depends on how much paint is present organic resins and how it is applied.

Properties of heat-resistant compositions:

  • Plastic. This is very important quality, because when heated, the metal is known to have the properties to expand, and the paint, respectively, should expand with it;
  • Electrically insulating properties. This property is of particular importance when it becomes necessary to paint the surfaces that can carry out electricity;
  • High anti-corrosion characteristics. The heat-resistant compositions are perfectly coping with rust prophylaxis on metal surfaces;
  • Preservation of initial qualities at different temperatures, both low and high.

Such paints are not thick and retain their properties even with long-term storage.

Colors

Usually, when choosing a color solutions for staining with heat-resistant dyes, preference is given to a limited set of colors. Most often black, white, silver (so-called “silver”) or chrome colors. Although many manufacturers today offer and more interesting colors that will help create unusual, but at the same time functional decors, such as red, blue, orange, crimson, brown, green gray, beige.

But at the same time it is necessary to remember that if the dye is used to decorate the furnace, it is better to use dark colors – so the furnace will warm up faster, and this leads to fuel economy – firewood or coal.

How to choose?

The degree of heat resistance determines the limit temperature that the stainable surface can withstand without changes in its appearance. Resistance to temperature depends on the operating conditions of the painted object. So, for example, a metal furnace is heated to 800 degrees, and heating radiators in apartment buildings – up to 90.

For coating of heating surfaces, refractory, heat-resistant and heat-resistant dyes are used. Heat-resistant paints are used for temperatures of not more than 600 degrees (metal furnaces or metal elements of furnaces, but not in the sauna). Refractory compositions are suitable for products, the conditions of operation of which are assumed to have a number of open sources. At average temperatures (no more than 200 degrees), high-temperature paints are used. They are suitable for painting engine parts, brick furnaces, heating radiators and heating pipes. For average temperatures, heat-resistant varnishes, withstanding heating up to 300 degrees. More decorative they look on brick surfaces, giving them radiance and shine.

The composition of the paint is of particular importance if the dye is selected for work indoors with people staying. In such cases, seemed to be supervised to the compositions with non-toxic components. In addition, the composition of the product indicates what temperatures it can withstand. For example, the heat-resistant paint with the temperature resistance of more than 500 degrees indicated on it cannot but contain metal powder (aluminum or zinc)

The presence or absence of anti-corrosion properties is also an important factor when choosing. So, for the color of heating devices in saunas or baths, it is required that the paint not only withstand high temperature, but also protected the metal equipment from moisture.

Time to the final drying of paint should not exceed 72 hours.
