Patent ID: 8303843

Claim:
A homogeneous cold-cure flexible foam activator blend comprising from ≧2 to ≦25% by weight, of an aqueous stabilizer formulation, from ≧1 to ≦20% by weight of a catalyst, from ≧1 to ≦90% by weight of a blowing agent, from ≧1 to ≦90% by weight, of at least one of a flame retardant, UV stabilizer, a dye, biocide, a pigment, a cell opener, a crosslinker and a foam-stabilizing substance, with the proportion by weight of the above-mentioned components being selected so that the sum of the proportions by weight of the components is 100% by weight, based on the aqueous cold-cure flexible foam activator blend, and wherein said aqueous stabilizer formulation consisting essentially of: a) from ≧0.1 to ≦80% by weight of at least one water-insoluble polysiloxane compound having a molecular weight of from ≧300 g/mol to ≦10 000 g/mol, said at least one water-insoluble polysiloxane compound is of the general formula (I): where the radicals R of formula (I) are each methyl, the radicals R 1 of formula (I) are each equal to R, n of formula (I) is from ≧0 to 50, m of formula (I) is from ≧0 to 50, k is from ≧0 to 10, with the proviso that n+m of formula (I)≧2 and n+m of formula (I)≦70, or of general formula III: where the radicals R of formula (III) are methyl, the radicals R 1 of formula (III) are each R, n of formula (III) is from ≧2 to 30, m of formula (III) is from ≧0 to ≦5, b) ≧2% by weight of water, c) ≧0.1% by weight of a surfactant, wherein said surfactant is other than a water-insoluble polysiloxane compound or a water-soluble siloxane, d) from ≧0 to 10% by weight of additives selected from the group consisting of thickeners, antifreezes, organic solvents and other biocides, and e) ≧0% by weight of water-soluble siloxane(s), with the proportion by weight of components a)-e) are selected so that the sum of the proportions by weight of the components is not more than 100% by weight, based on the aqueous stabilizer formulation.
