The invention relates to an insulation-layer forming composition which contains a binding agent based on an alkoxy silane-functionalized polymer which support alkoxy-functionalised silane groups, an insulation-layer forming additive and optionally, a crosslinking agent. The claimed composition, which has a relatively high expansion rate, makes it possible to apply, in a simple and rapid manner, coatings that have the layer thickness required for the particular fire resistance time, the layer thickness being reduced to a minimum while achieving a great insulating effect. The claimed composition is particularly suitable for fire protection, especially as a coating for steel components such as pillars, beams and truss members, for increasing the fire resistance time. |
