Starting a renovation, we are faced with many problems that require an effective solution. For example, there are many different communications in the house that need protection from exposure to high temperatures.
Processing materials
Of course, today there is a significant selection of different materials, but which one will be needed in a particular case? When metal elements are constantly or occasionally affected by high temperatures, heat-resistant enamels will help protect them. Items that require special care may be:
- Chimney.
- Oven.
- Heating batteries.
- Pipes for various purposes.
- Automotive parts.
Composition of enamels
As mentioned above, metal enamel is a familiar paint, which means it would be useful to recall what it is. The production of heat-resistant paints is no different from the creation of other similar materials, but they have a special composition that makes products resistant to high temperatures.
Heat-resistant enamels are made from a varnish solution, but in addition to color pigments,many other fillers are added, depending on the desired properties. The latter components, in turn, affect the purpose of the paint. For example, heat-resistant black enamel is used only for processing ferrous metals, there are types designed exclusively for non-ferrous, and there is also a material that is used for working with any metal.
Specific usage
Certain composition can make the paint resistant to corrosion and chemical materials. There are products that are waterproof and repel any natural precipitation. Therefore, the presence of fillers in the composition of the enamel is important. In turn, the coloring pigment is used only to give a certain color and does not affect its properties. The main enamel colors available in the store are black and white, and color options are also made in case the interior of the room requires it.
The main task performed by the heat-resistant enamel "Certa" is the preservation of metal communications exposed to high or low temperatures. It is worth considering that, depending on the temperature ranges, it is necessary to select the type of enamel separately.
Heat-resistant paint is able to keep the metal at a temperature of + 500 Celsius, and this is due to the addition of special metal powder to the composition, which does not allow the temperature to penetrate the surface, and therefore preserves the integrity of the metals. When choosing the type of enamel, there are also many different factors to consider.
Varieties of enamels
Let's consider the types of enamel depending on various properties:
- Weather Resistant - Used on low carbon steel. It is considered a quick-drying material, has anti-corrosion components. Enamel contains zinc.
- Petrol resistant - used in shipbuilding, machine building, aircraft building, for processing railway and automotive equipment in conditions of increasing levels of corrosive substances. It is often used for processing containers for storage, transportation of fuels and lubricants. Enamel contributes to the long-term preservation of various metal surfaces.
- Chemical resistant - designed for painting surfaces that are under the constant influence of various acids and chemical materials. It has increased water resistance, does not lend itself to temperature changes, removes mold, fungi and is an environmentally friendly material.
Influence of additives
As already mentioned, to achieve heat resistance, various additives are included in the paint, depending on the required characteristics. The addition of organic resin to the enamel increases the time for complete drying, the component makes it more elastic and has a positive effect on the quality of protection.
Also, aluminum powder is often added to heat-resistant enamel, which raises the level to a temperature of +600 degrees. Most often, this additive is located in the upper layers.paints, which allows you to create a layer on the surface with a high level of protection from external influences. Enamel Certa, having this additive in its composition, contributes to the correct distribution of temperature over metal communications, which means it prevents overheating and the development of corrosion processes, especially at welds.
Temperature classification of enamels
Enamel for metal is distinguished not only by properties, but also focusing on temperature:
- Colors without additives can withstand 80-degree temperatures.
- When the surface is affected by +100 ⁰С, acrylic or alkyd paint is used with the addition of appropriate pigments. Thanks to them, the original appearance of the surface is preserved for a long time, fading, tarnishing and excessive heating are prevented. Most often released by manufacturers in the trade in the form of aerosols.
- Temperature from 80 to 120 ⁰С implies the use of polyurethane, acrylic paint and epoxy heat-resistant enamel.
- Heat-resistant acrylic, epoxy and polyurethane enamels are used for processing metal under the influence of +200 ⁰С.
- At temperatures from 200 to 400 ⁰С, one-component paint materials with the addition of aluminum powder are used.
- To work with temperatures above 500 degrees, heat-resistant enamel is used with the addition of silicone, aluminum and zinc powder. Most commonly available as a spray and aerosol.
Based on these data and taking into accountcomposition and properties, price may vary. Heat-resistant enamel is made by certain components in its composition, so such inclusions inevitably affect pricing. Also, the region of sales is reflected in the cost. On average, Certa enamel costs from 370 rubles. per kg.
The difference between enamel and paint
To be able to properly use heat-resistant materials, it should be understood that there are many types of such products. Enamel is a suspension consisting of varnishes mixed with pigment, as well as various additives. Dried enamel creates a film on surfaces that has an opaque structure. The outer coating must be durable and help extend the life of various work surfaces. And here both paint and enamel do an excellent job.
The composition of both is often almost identical, but despite this there is a certain difference between them. There is an erroneous tendency: people believe that paints give the surface insufficient gloss. Enamel has different physical and chemical properties, but like paint, it forms a film on the surface. At the same time, the second type of funds is much stronger, more elastic and harder. But the heat-resistant Zerta enamel creates a layer that makes the surface more attractive.
Preparatory work
Initially, you need to prepare the surface for applying enamel. To do this, it must be cleaned of old paint, rust, dirt and dust. Immediately before applying the enamel, the surface will need to be degreased using a solvent.
Next, carefully mix the paint,redistributing the additives and dissolving the sediment. In cases where pure enamel is too thick, it can be made liquid by mixing with a solvent.
