A stable polyol pre-mix composition comprises a blowing agent, a polyol, a surfactant, and a catalyst composition comprising an oxygen-containing amine catalyst and a metallic salt. The oxygen-containing amine catalyst may be, for example, one or more of an alkanol amine, an ether amine, or a morpholine group-containing compound such as, for example, 2-(2-dimethylaminoethoxy)ethanol or N,N,N'-trimethylaminoethyl-ethanolamine. The metallic salt may be, for example, alkali earth carboxylates, alkali carboxylates, and carboxylates of metals selected form the group consisting of zinc (Zn), cobalt (Co), tin (Sn), cerium (Ce), lanthanum (La), aluminum (Al), vanadium (V), manganese (Mn), copper (Cu), nickel (Ni), iron (Fe), titanium (Ti), zirconium (Zr), chromium (Cr), scandium (Sc), calcium (Ca), magnesium (Mg), strontium (Sr), and barium (Ba).
