Mounting foam fire-resistant: characteristics

Foam mounting foam is used when there is a need to make insulation that will be exposed to fire during operation.

Characteristics of fire-resistant foam

The assembly foam is a one-component sealant made of polyurethane foam. Once purchased, you can use it immediately. In the process of application, its components polymerize by interacting with the moisture particles that are contained in the external environment. Mounting foam fireproof has among the ingredients special substances that guarantee excellent acoustic, as well as thermal qualities. The formed interlayer is absolutely impermeable to gas and smoke.

Foam Features

Mounting foam fireproof does not burn with direct exposure to fire within the time specified by the manufacturer. After application does not drain down, even if it appears on a vertical surface. Among its positive characteristics can be distinguished ability to completely fill the space of any form. It perfectly adheres to brick surfaces and bases made of wood, polymers, cement, steel and glass.

The material well resists the effects of water and mold, has the ability to undergo temperature changes ranging from -60 to +100 ^o C. Quite often, builders and household craftsmen compare the described material with analogs that have traditional qualities. In this fight, the first version of foam comes out victorious, it is more durable and reliable.

Mounting foam fireproof can have a different period until the moment of ignition. For example, Soudal brand material will not burn for 360 minutes when exposed to a flame. Foam has the ability to self-extinction. This indicates that the foam is hardly flammable, and if it is exposed to direct fire, it will not form hot drops. At the time of elimination of the flame, the foam will self-extinguish. As one drawback, you can identify sensitivity to the effects of sunlight. That is why foam implies the need for protection after hardening.

Rules of application

Mounting foam fireproof should be applied to the surface, the temperature of which is in the range from +5 to +30 ^o C. The working temperature of the inner contents of the cylinder should not exceed the range from +10 to +30 ^o C. In order to prepare the foam for use, its It is necessary to withstand at room temperature, but it is impossible to heat up. Store cylinders is recommended in the premises, placing the neck up.

Foam mounting polyurethane fireproof before application should be well shaken. Then you need to analyze how well it comes out of the cylinder. After stabilizing the output, it is permissible to start working. In order to achieve better adhesion, it is necessary to wet the working surface with water. However, there should not be any drops on the surface. Cavities do not need to be filled more than 1/3. After a day, the foam should gain its ultimate strength. It is recommended to close it with plaster or sealant, which has fire-resistance qualities.

The cost of foam

Depending on the manufacturer and special additives, the mounting foam fire-resistant B1 can cost differently. The price affects the sales region. So, a balloon in which 750 ml of the formulation can be purchased for 350 rubles.

The application of foam should not be carried out in excess. First of all, this will lead to a material overexpenditure and will entail labor costs aimed at eliminating the surplus after hardening. After all, the material increases in size. Therefore, before starting work it would be good to try to apply foam to a small area.
