ABSTRACT:
A catalyst composition for catalyzing a polyurethane forming reaction includes a gelling catalyst and a blowing catalyst selected such that the resulting polyurethane foam has a low level of volatile and/or malodorous material in it. The gelling catalysts are selected from tertiary aminoalkyl substituted primary or secondary amines; and the blowing catalysts are selected from bis(aminoalkyl) ethers comprising alkanol moieties, primary amine moieties, or ureido moieties derived from such primary amine moieties.
