Abstract

The invention relates to curable compositions comprising a) at least one organic polymer selected from polyethers and polyacrylic acid esters, wherein the organic polymer has at least one defined, cross-linkable end group having at least one C1-C8-alkoxy- or C1-C8-acyloxy radical, b) at least one poly(dialkylsiloxane) having at least one defined, cross-linkable end group having at least one vinyl radical and likewise at least one C1-C8-alkoxy- or C1-C8-acyloxy radical and c) at least one flame-retarding additive selected from red phosphorus, organic phosphor compounds, ammonia polyphosphate, metal hydroxides, expandable graphite, zinc borate and melamine salts, to the use of such compositions as adhesive, sealing or coating material, in particular for providing a substrate having a flame-retardant, elastic coating, to a coating thus obtained and to the use of at least one poly(dialkylsiloxane) b) to improve the fire properties of a curable composition comprising at least one organic polymer a).
