"Thermobarrier", fire retardant paint: consumption, characteristics

Bearing metal structures are the most durable products that can withstand many disasters, but not against all: unfortunately, even metal can not withstand the pressure of fire. This is very dangerous, because in a critical situation, buildings can collapse before the fire brigade arrives, which is fraught with death. To avoid this, metal structures are treated with substances that prevent the effects of fire. In particular - fireproof paint "Thermobarrier".

Manufacturer Information

The production of various types of fire retardant coatings is carried out by the company "OgneKhimZashchita". Among its products is fireproof paint “Thermobarrier”, which was developed taking into account the latest scientific achievements.

To check the quality of the product, it is tested in practice. The basis of testing is the carefully studied fire requirements of various structures.

The product is used to increase the fire resistance of metal structures in the construction of civil and industrial facilities.

Material Features

During combustion, surfaces treated with a substance give off gases under the influence of high temperatures. They perform a dual function: they prevent strong fires and contribute to the formation of a coke layer. It has lower heat-conducting properties, therefore it does not allow high temperatures to penetrate the metal.

Due to this, the destruction of the structure either proceeds much more slowly or does not occur at all - it all depends on the strength of the fire.

The advantages of this substance include the following characteristics:

1. The use of paint does not lead to weighting and, as a consequence, to deformation of the structure.
2. After a fire, the protective layer can be quickly restored.
3. Easy to apply with a regular roller, brush or spray.
4. The material remains stable after use for 20 years or more - it depends on the operating conditions. To extend the validity in open space, it is advisable to additionally apply a protective layer on top of the paint.

In addition, the coating also has decorative properties, which is important.

Specifications

The main feature of the "Thermobarrier" fire retardant paint is the possibility of its application throughout the year: the substance retains its characteristics and properties at temperatures from +35 to -35 degrees. When applied, the substance forms a dense layer that does not drain even from vertical surfaces. The paint acquires fire-retardant characteristics after 40 minutes - 2 hours after application: the exact figure depends on the ambient temperature (the warmer it is outside, the faster the drying process takes place).

Due to quick drying and high fire retardant properties, the construction time and construction of fire-fighting systems can be significantly reduced at the construction site.

Distinctive technical characteristics of fireproof paint "Thermobarrier" are the following indicators:

1. White color.
2. Matte coating.
3. Intumescent type.
4. According to GOST R 53295-2009, depending on the type of paint, it can belong to the 2-5th groups of fire-retardant efficiency.
5. The temperature limit is -45 / + 45 degrees C.
6. Fire resistance reaches a maximum of 2 hours.

Safety precautions

The manufacturer of flame retardant paint for metal "Thermobarrier" recommends that the following rules be observed when working with the substance:

1. Do not work near open flames.
2. When working, use personal protective equipment.
3. If work is carried out indoors, for safety it is required to provide in it excellent ventilation.
4. The substance must not be allowed to enter the digestive organs, respiratory tract.
5. If the paint gets on the skin, it must be washed off immediately with any soap and warm water.

Preparation for work

Apply fire-retardant paint "Thermobarrier" is possible only on surfaces that have been previously primed. In this case, the primer layer must have a minimum thickness of 50-55 microns. Spraying the coloring matter is possible only after the primer is completely dry and there are no areas on the surface with corrosion, delamination, damage. In addition, the surface must be dry, without vapor, frost, snow.

Before work, the substance is mixed with a construction mixer until smooth. After the procedure, the material should stand for at least 30 minutes so that all air bubbles come out of it.

Consumption of fireproof paint "Thermobarrier" depends on the thickness of the applied layer. For example, with a coating thickness of about 0, 60 mm will be needed per 1 square. m about 1 kg of paint, with a layer thickness of 0.85 mm - over 1.25 kg. If the coating thickness is 2.45 mm, 3.6 kg of paint will be needed per square meter.

Features of working with different surfaces

Work with metal surfaces:

1. Prepare the surface. The degree of purification is up to pure metal. If there are areas that do not hold firmly or there is rust on their surface, they must be thoroughly cleaned with an abrasive blasting device or mechanically. Then solvent degreasing is carried out.
2. Apply a primer.

Work with primed surfaces:

1. Assess the condition of the primer. If defects are found - they need to be eliminated.
2. Remove dust and degrease with solvent.
3. When the soil is completely dry, spray the fireproof paint “Thermobarrier”.

Work in the repair of coatings:

1. Mechanically remove all damage. If there are signs of corrosion, they are cleaned.
2. The prepared surfaces are dust-free and degreased.
3. Primed prepared surfaces.
4. After the soil has completely dried (at least 7 days), paint is applied.

Paint recommendations

The manufacturer recommends applying flame retardant paint "Thermobarrier" by airless spraying when carrying out fireproof work of large volumes. If the areas to be treated are small or in hard to reach places, you can use a brush. After drying, the coating will have a thickness of about 0.7 mm with airless spraying, and with a brush - 0.5-0.6 mm.

If airless spraying is used, the following rules are recommended:

1. Spray paint at an angle of 30-50 °.
2. Pressure level - from 20 to 25 MPa.
3. The spray nozzle should have a diameter of 0.50 to 0, 68 mm.
4. If necessary, you can add a diluent, but not more than 5% of the total.

Storage, transportation

It is unacceptable to store the fireproof paint "Thermobarrier" near an open flame. The most admissible storage temperatures are from +45 to -45 ° . All the storage time, during transportation, during loading and unloading operations, it is necessary to protect the packaging from damage and overturning. To store the paint you need to packed in a factory container. The best place to save is a covered room, which does not get moisture and sunlight.
