An insulation-layer-forming composition is described, which contains a binder on the basis of an alkoxysilane-functionalized polymer, which carries alkoxy-functionalized silane groups, an insulation-layer-forming additive, and, if applicable, a crosslinking agent. By means of the composition according to the invention, the expansion rate of which is relatively high, coatings having the layer thickness required for the respective fire-resistance duration can be applied in simple and rapid manner, wherein the layer thickness can be reduced to a minimum and nevertheless, a great insulating effect can be achieved. The composition according to the invention is particularly suitable for fire-protection, particularly as a coating for steel structural parts, such as supports, beams, frame members, to increase their fire-resistance duration. |

1. An insulation-layer-forming composition, comprising:
a) an alkoxysilane-functional polymer, which contains an alkoxy-functional silane group having the general Formula (I), terminated and/or as side group along the polymer chain,
—Si(R1)m(OR2)3−m (I), in which R1 stands for a linear or branched C1-C16 alkyl radical, R2 stands for a linear or branched C1-C6 alkyl radical, and m stands for a whole number from 0 to 2; and b) an insulation-layer-forming fire-protection additive. |
