Stabilization of thermosetting foam blends containing halogenated olefin blowing agents. The object is to provide a halogenated hydroolefin blowing agent, a polyol, a surfactant, and the following chemical structure: R1R2N (CH2) 2X (CH2) 2Y (wherein R1 and R2 are the same or different). Each of which is a C1-C6 alkyl group and / or an alkanol group, X is O or NR3 and / or can be terminated with OH, wherein R3 is a C1-C6 alkyl group A group or an alkanol group, Y is OH or NR4R5, wherein R4 and R5 are the same or different and are each a C1-C6 alkyl group or an alkanol group, provided that the compound is at least A catalyst composition comprising an oxygen-containing amine catalyst having an ether and / or hydroxyl group) and one or more metal salts. A polyol premix composition, wherein the catalyst composition comprises two or more amine catalysts, the oxygen-containing amine catalyst comprises more than 50% by weight of the total amine catalyst, and the blowing agent is This is solved by a stable polyol premix composition containing olefins.
