Abstract
Abstract A method for the manufacture of urethane-modified polyisocyanurate foams in which an isocyanate is blended with a "B" side comprising a polyol blend, a surfactant, a blowing agent, and a catalyst. The polyol blend comprises at least 5% (wt.) of a mixture of a polyalkoxylated amine and a polyalkoxylated quaternary ammonium borate ester, at least 40% (wt.) of a resin polyol, with any remainder being a polyether or polyester polyol. All components of the "B" side will remain a homogeneous liquid without phase separation and without the need for agitation for at least 7 days after blending. The resin polyols are preferably moderate viscosity, aromatic polyester polyols derived from polycarbomethoxyl-substituted diphenyls, polyphenyls, and benzyl esters of the toluate family.
