Abstract

Described is an insulation layer-forming composition containing a binder that is based on a compound having low-electron multiple carbon bonds and a carbanion-forming compound. The disclosed 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 disclosed 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.
