  • the main domain of application is the assembly and filling of gapsbetween the windows or doors and the wall, filling of pipe penetrations and other applications in the building engineering and other technical branches.
  • IK foams one-component polyurethane foams that are also called the IK foams. These originate during the use by the release of prepolymer mixture from the aerosol container with the help of propellant gas.
  • the IK foams with the density of 10-30 g/1, hardened under the influence of air moisture can be afterwards worked mechanically.
  • the two-component polyurethane foams are also called the 2K foams.
  • the density of 2K foams amounts to 10-100 g/1.
  • the density of this foam known as 1,5K foam, amounts to 10-60g/l.
  • the prepolymer mixtures for the production o f polyurethane foams contain the prepolymer component with the minimum content of NCO reactive groups.
  • the prepolymer is the polymer with the appropriate viscosity, containing the terminal NCO groups.

Also both isomers of TDI can be used separately or in the mixture.
  • the isocyanates are subjected to the reaction with the poly ethers, polyesters or polyalcohols containing the hydroxyl groups, but one should take care of the proper viscosity of prepolymer.
  • the polyurethane prepolymers that can be used for the production of polyurethane foams in the aerosol containers have the residual content of non-reacted isocyanate monomer, amounting up to 40%. This residual content depends on the production conditions.
  • the isocyanate monomers in spite of their low volatility are dangerous considering their toxicity and there is an obligation to mark their presence.
  • the monomer isocyanate groups are highly reactive and in living organisms their irritating and toxic action can be observed.

Apart from the widely known good insulating properties these foams have some more favourable properties that introduced their application to many useful purposes. These properties are, among others, exceptionally easy handling, fast hardening, good adhesion to the existing base, good characteristics of complete filling and foaming and even the good tolerance of living organisms in relation to the hardened product. In fact the ready polyurethane foams can be classified as the non-toxic products.
