The present invention relates to:
(1) a catalyst for producing a rigid polyurethane foam by means of at least one blowing agent selected from the group consisting of 1,1,1,3,3-pentafluoropropane (HFC-245fa), 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and a low boiling point hydrocarbon, which comprises:
(A) an aliphatic amine compound and at least one amine compound selected from the group consisting of triethylenediamine, N,N,N',N'-tetramethyl-1,6-hexanediamine and N,N-dimethylcyclohexylamine: or
(B) an amine compound having an alkyl ether group and/or an aryl ether group in its molecule;
(2) a catalyst for producing a rigid polyisocyanurate foam by means of at least one blowing agent selected from the group consisting of 1,1,1,3,3-pentafluoropropane (HFC-245fa), 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and a low boiling point hydrocarbon, which comprises an aliphatic amine compound and a polyisocyanurate catalyst and
(3) a process for producing a rigid polyurethane foam excellent in the adhesive strength and flame retardancy of the foam and
(4) a process for producing a rigid polyisocyanurate foam excellent in the flame retardancy, adhesive strenght and dimensional stability of the foam.
