| 20080298165 | Method for Preparing a Silicate-Based Foam, Device for Using this Method, Aerosol Can and Foam Product Obtained by the Method - Method for preparing a silicate-based foam by mixing the silicate anti a pressurized carrier gas, characterized in that an accelerator, which causes the silicate to harden by chemical reaction, is added to the silicate. The accelerator can be selected from acids and acid-forming substances. While retaining the good properties and possible applications of the foam prepared in accordance with the prior art, this foam is improved by preparing a solid foam, i.e. a foam which remains foam after drying. This solid foam, inherently, i.e. without any reinforcing agent or filler, has a good dimensional stability. Devices for applying the method, an aerosol can in which the method is applied, and a prepared foam product. | 12-04-2008 |
