The present invention relates to one component polyurethane foam compositions which comprise mixtures of prepolymers of a polyol and an excess of isocyanate; the usual adjuvants for polyurethane foams, an expanding gas under pressure and a polysiloxane compound with antifoam activity stored in a valved pressure vessel.

Composition for the production of polyurethane foam materials having

A process for producing in situ foams based on alkali metal silicates characterized in that an aqueous alkali metal silicate solution on the one hand and a hardener solution on the other hand are accomodated in separate pressurized containers A and B, prior to use the hardener solution in container B is added to and mixed with the silicate solution in container A in the presence of a suitable emulsifier for foam formation and a propellent gas liquid under high pressure between 0.degree. and 50.degree. C., and, on actuation of the discharge valve of container A, an alkali metal silicate foam is discharged. The alkali metal silicate foams formed are distinguished by non-inflammability, high temperature stability and good heat-insulating properties and are used as a filling, construction and insulating material or the like in the building industry.

In a device for dosing two-component products of a predetermined mixing ratio, the dispensing accuracy has been improved in conjunction with simple design and uncomplicated operation. According to the invention, two chambers are provided which are put under pressure by means of two pistons that are displaced simultaneously in opposite directions from a starting point. A mixer means is arranged at the closed longitudinal end of a first chamber, while the closed longitudinal end of the other chamber is connected to the mixer means over a component line that leads centrally through the first chamber.
