Starting repairs, we encounter many problems that require an effective solution. For example, in a house there are many different communications that need protection from exposure to high temperatures.
Materials for processing
Of course, today there is a significant selection of different materials, but which one will be needed in a particular case? When high temperatures constantly or sometimes affect metal elements, heat-resistant enamels will help to protect them. Elements that require special care may include:
- Chimney.
- Oven.
- Heating batteries.
- Pipes for various purposes.
- Automotive parts.
Enamel Composition
As mentioned above, metal enamel is a familiar paint, which means that it will 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 gives products resistance to high temperatures.
Heat-resistant enamels are made of 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 intended exclusively for non-ferrous metals, and there is also a material that is used to work with any metal.
Specifics of use
A certain composition can make paint a tool that is not susceptible to corrosion and the influence of chemical materials. There are waterproof and repellent products of any natural precipitation. Therefore, the presence of fillers in the enamel is important. In turn, the coloring pigment is used only to impart a certain color and does not affect its properties. The main colors of enamel, which can be purchased at the store, are black and white, and color options are also made for the case when the interior of the room requires it.
The main task performed by the heat-resistant Tserta enamel is to preserve metal communications exposed to high or low temperature. 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 preserve 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 temperature to penetrate the surface, which means it preserves the integrity of metals. When choosing the type of enamel, it is also necessary to consider many different factors.
Varieties of Enamels
Consider the types of enamel depending on various properties:
- Weatherproof - used for processing steel with a low carbon content. It is considered a quick-drying material, has anti-corrosion components. Enamel contains zinc.
- Petrol-resistant - it is used in shipbuilding, engineering, aircraft manufacturing, for the processing of railway and automotive equipment in conditions of increasing levels of corrosive substances. Often used for processing containers for storage, transportation of fuel and lubricants. Enamel contributes to the long-term preservation of various metal surfaces.
- Chemical resistant - designed for painting surfaces under the constant influence of various acids and chemical materials. It has increased water resistance, is not amenable to temperature changes, removes mold, fungi and is an environmentally friendly material.
The effect of additives
As already mentioned, to achieve heat resistance in the paint include various additives, depending on the required characteristics. The addition of organic resin to the enamel helps to increase the time of complete drying, the component makes it more elastic and positively affects the quality of protection.
Also, aluminum powder is often added to heat-resistant enamels , which increases the level to a temperature of +600 degrees. Most often, this additive is located in the upper layers of paints, which allows you to create a layer on the surface with a high level of protection against external influences. Enamel Certa, having in its composition this additive, contributes to the correct distribution of temperature over metal communications, which means that it prevents overheating and the development of corrosion processes, especially at welds.
Temperature classification of enamels
Enamel on metal is distinguished not only by properties, but also focusing on temperature:
- Paints without additives are able to withstand the influence of 80 degrees.
- When the surface is influenced by +100 ⁰ - acrylic or alkyd paint is applied with the addition of appropriate pigments. Thanks to them, the initial appearance of the surface for a long time is preserved, fading, tarnishing and excessive heating are prevented. Most often sold by manufacturers in the form of aerosols.
- Temperature from 80 to 120 ° C implies the use of polyurethane, acrylic paint and epoxy heat-resistant enamel.
- Acrylic enamels are heat-resistant, epoxy and polyurethane are used for processing metal under the influence of +200 ⁰.
- At temperatures from 200 to 400 ° C, one-component paint materials with the addition of aluminum powder are used.
- To work with temperatures above 500 degrees, heat-resistant enamel with the addition of silicone, aluminum and zinc powder is used. Most often produced in the form of a spray can and aerosol.
Focusing on these data and taking into account the composition and properties, the price may change. Certain components in its composition make heat-resistant enamel, so such inclusions will inevitably affect pricing. The cost also affects the sales region. On average, the Tserta enamel costs from 370 rubles. per kg
The difference between enamel and paint
In order to be able to correctly use heat-resistant materials, it should be understood that there are many types of such products. Enamel - a suspension consisting of varnishes mixed with pigment, as well as various additives. The dried enamel creates a film on the surfaces that has an opaque structure. The outer coating should 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 trend: people believe that paints give the surface a lack of gloss. Enamel has other physicochemical properties, but, like paint, forms a film on the surface. At the same time, the second type of funds is much stronger, more elastic and firmer. But the heat-resistant Tserta 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, mix the paint thoroughly, redistributing the additives and dissolving the precipitate. In cases where the enamel in its pure form has a too thick structure, it can be made liquid by mixing with a solvent.
