摘要
The subject matter of the present invention relates to a low-viscosity aqueous hot-cure flexible polyurethane foam stabilizer solution which can be used in the production of hot-cure flexible polyurethane foams, wherein the low-viscosity aqueous hot-cure flexible polyurethane foam stabilizer solution comprises the following components: ≧40% to ≦70% by weight of polyethersiloxane, ≧0.5% to ≦20% by weight of organic surfactant, ≧10% by weight of water, ≧0% by weight of organic solvent additions, in which the polyethersiloxane has the following formula (I) —R1—Si(CH3)2O—[Si(CH3)(OSi(CH3)2R0)O—]u—[Si(OSi(CH3)2R0)2O—]v—[Si(CH3)2O—]w—[SiCH3R2O—]x—[SiCH3R3O—]y—[SiCH3R4O]z—[SiR3R4O]t—Si(CH3)2—R5 (I).
