Fire retardant coatings for metal structures. Fire protection of metal structures


Many compositions are based on elements such as

  • liquid glass,
  • cement,
  • granulated mineral fiber, etc.

The fire-fighting effect of such paints lies in their swelling at a temperature of 170-200 ° C. The composition forms a heat-insulating porous layer, the thickness of which reaches several centimeters. If fire protection is carried out correctly and taking into account the lightweight coating, plaster composition, fire retardant boards and sheets, it is possible to achieve a fire resistance limit of 0.75-2.5 hours. Blowing paints have a fire resistance limit of 0.75 to 1.5 hours Below you can see the fire protection products for metal protection that are available in our store.

We offer high-quality and effective fire-retardant paint for metal structures various types. These are mainly steel structures for construction or industrial purposes. Existing fire retardant compounds are guaranteed to increase the level of fire protection of metal structures up to a given time. Corporate products last for a long time, while having an affordable price.

The action of fire retardant paint is based on the formation of a durable coating on the surface of metal structures. Depending on the resulting coating layer, a given fire-retardant efficiency is obtained, measured in minutes. Polyus products meet all requirements fire safety.

TERMA LUX paint is intended for fire protection of steel building structures of public and industrial buildings with a non-aggressive environment and a relative humidity of no more than 80%. Increases the fire resistance limit of metal structures to 90 minutes.

The paint is a water-based intumescent system. It is manufactured using the latest technologies, using nanosynthesis products in its composition, which significantly increase the technological and fire-retardant properties of the material. Ideal for airless application.

The paint is fire and explosion proof. "TERMA LUX" is environmentally friendly during application and operation.

The paint is supplied ready to use, white and has an aesthetic appearance(decorative finishing). To order, it is tinted in individual colors with the possibility of obtaining intense shades.

The fire-retardant effect of TERMA LUX paint is due to the formation of a heat-insulating foamed mineral-coke layer that prevents the spread of fire and heating of the metal structure.

Fire-retardant paint "TERMA LUX" meets the fire safety requirements established by NPB 236-97. The main indicators of fire retardant efficiency are given in the table according to certificate No. SSPB.RU.OPO41.N.00146 until 06/02/2011.

The consumption for obtaining a dry fire retardant layer 1 mm thick without taking into account losses is 1.7 kg/m2.

Before fire-prevention treatment of metal structures, the paint should be mixed and, if necessary, diluted with water to working viscosity (but not more than 3-5% by weight). The paint is applied to the prepared (GOST 9.402-2004), primed with anti-corrosion primer GF-021 metal surface. The paint is applied layer by layer using a brush or mechanized using airless spraying devices with electric or pneumatic drive such as Contracor, Wagner, Uniblast, Graco, etc.

The fire retardant coating “TERMA LUX” is repairable and, subject to recommendations and operating conditions, retains its properties for at least 15 years.

Fire-retardant paint "Krauz-R" is supplied in the form of a ready-made composition. After drying, it is fire and explosion proof, non-toxic and does not emit environment harmful substances in concentrations hazardous to human health. Fire safety precautions must be observed during storage and application.

Before use, it is necessary to mix thoroughly (if possible, with a power tool, with a frequency of 120-300 rpm). If the paint thickens, it is possible to dilute it with a solvent or thinner in an amount of no more than 5% of the paint weight. Add the thinner in a thin stream into the container with paint, continuously stirring with a mechanized stirrer (mixer) until the required viscosity is achieved (conditional viscosity at a temperature of (20±2)°C according to a B3-246 viscometer with a nozzle diameter of 8 mm is not less than 200c). The use of water as a diluent is not permitted. The paint is applied to the surfaces of metal structures primed with GF-021 (GOST 25129-82). Surfaces must be cleaned of dirt, dust, and degreased (white spirit, solvent, or soap solution). Areas with traces of rust must be cleaned and primed. Application of paint is possible after 72 hours after priming. If a primer other than GF-021 is used, it is necessary to carry out test paints in order to check the quality of adhesion and possible reaction with the primer layer.

Application work can be carried out at ambient temperatures below 0 o C, with a relative air humidity of no more than 80%. When applying paint in conditions of negative temperatures, the container with paint must be kept in a warm room for at least 2 - 3 hours. The paint is applied with a brush, roller, or airless sprayer in several layers; it is possible to apply the first layer with a wet layer thickness of up to 0.9 mm. The period of interlayer drying is 4-6 hours (depending on the applied thickness of the wet layer). Complete drying and acquisition of the required fire retardant effectiveness occurs no earlier than after 48 hours. Do not carry out work on applying fire-retardant paint if frost forms on the metal structures or condensation forms, or there is direct contact with atmospheric precipitation (rain, snow). If the ambient temperature drops and the humidity rises above 80%, drying between layers and the time for complete drying of the paint increases.

Paint consumption according to the certificate is (taking into account the thickness of the dry layer of GF-021 primer 0.05 mm):

6th group of fire-retardant efficiency (30 min) - with a dry coating layer thickness of at least 0.60 mm and paint consumption of at least 1.00 kg/m2, excluding losses (reduced metal thickness - 2.8 mm);

5th group of fire-retardant efficiency (45 min) - with a dry coating layer thickness of at least 1.00 mm and paint consumption of at least 1.67 kg/m2, excluding losses (reduced metal thickness - 2.8 mm);

4th group of fire-retardant efficiency (60 min) - with a dry coating layer thickness of at least 1.26 mm and paint consumption of at least 2.1 kg/m2, excluding losses (reduced metal thickness - 4.8 mm);

3rd group of fire-retardant efficiency (90 min) - with a dry coating layer thickness of at least 2.05 mm and paint consumption of at least 3.42 kg/m2, excluding losses (reduced metal thickness - 4.1 mm).
