Soudal polyurethane foam: characteristics and features of use

Extensive use of polyurethane foam due to its technical characteristics, as well as ease of use. Among the huge number of manufacturers of these products, Soudal products deserve special attention.

Specifications and properties

Foam assembly Soudal is made on the basis of a material that has a high ability of adhesion of various surfaces. The sealing mixture is made on the basis of polyurethane.

Curing of the foam occurs at a high humidity of 60% and a temperature of 20 degrees above zero. Already after 8-10 minutes, the upper film layer is formed. After approximately 25-30 minutes, the surface becomes completely dry. However, it should be noted that the rate of solidification increases depending on the size of the gap.

The hardened sealant has a dense consistency. Closed pores make up 80% of the entire surface. The density of the substance is 26 kg / m3.


Foam is available in cans, the volume of which is 300 ml, 500 ml, 750 ml. Professional foam can have a can volume of 1 thousand ml. It should be noted that with a volume of 300 ml, up to 30 liters of the substance can be obtained at the outlet. The volume of 500 ml cartridges gives up to 40 liters of the substance. If the volume is 750 ml, the output is up to 50 liters of the substance.

After hardening, the mixture usually has a yellowish or greenish tint. Dark saturated color is a sign of the destruction of a substance under the action of sunlight.

Keep sealant in a cool place for no more than one year.

It should be noted that the extreme temperature limits when working with this material is a temperature from 5 to 35 degrees above zero.



Fire-resistant foam Soudal is characterized by versatility of application. Due to the presence of high temperature resistance in the solid state, it retains its properties at temperatures from minus 40 degrees to plus 90 degrees.

The material has special technical characteristics:

  • high refractoriness;
  • Bending strength index corresponds to 17 N / cm2;
  • sound insulation is 58 dB;
  • compressive strength is 3N / cm2;
  • moisture permeability is 1%;
  • resistance to bending is 7N / cm2.

Professional and household foam differs in the type of valve of the cartridge into which the sprayer is inserted.

The sealant is produced using modern technologies and meets the existing quality standards. The presence of the certificate confirms the absence of impurities to the environment. With proper use of foam, there should be no crumbling processes, destruction.

Before you start working with sealant, it is necessary to conduct preparatory activities, which include a number of sequential actions.

  • A can of foam is taken from a cool storage place and kept at room temperature until its temperature is the same.
  • The surface on which the sealant will be applied is thoroughly cleaned of dirt, dust, foreign particles.
  • For better adhesion of the sealant to the outer surface, it must be moistened with water.
  • Before applying the sealing agent, it is necessary to remove the protective valve.
  • If a pistol is to be used for work, then it is connected to a spray can.
  • Spray needs to be shaken up.
  • The substance is applied by placing the can upside down.
  • After work, make cleaning, leveling the surface. Excess can be easily removed with acetone or any other solvent. After hardening of the foam, the stripping can be done only with the use of mechanical means.

There is a special 500 ml Soudal foam cleaner that is used to flush the sealant from glass, wood, plastic, metal surfaces. It is also used to clean the mounting gun, balloon valve. This substance effectively degreases the surface.

Due to its properties, the sealant is successfully used to fill voids, slots:

  • when warming any building structures;
  • at installation of window, door designs;
  • with the help of a sealant, fill empty areas of heating and cooling systems;
  • foam provides reliable insulation of piping systems;
  • sealant provides reliable sound insulation, so it is effectively used when installing any partitions or floors;
  • foam is used in the construction of the walls of the bath, sauna, when laying fireplaces, stoves.
