ABSTRACT Organic antimony compounds can be used to retard deactivation of urethane catalysts during storage of a B side formulation containing aromatic polyester polyols, used in the manufacture of rigid polyurethane foams. Accordingly there is described such a composition comprising an aromatic polyester polyol, a surfactant, a tertiary amine catalyst, and an organic blowing agent. The combination additionally comprises an organic antimony compound that is soluble in the polyol to retard the deactivation of the catalyst.
