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 optionally, 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 45% (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 3 days and 7 days after blending.
