This invention relates to a process for the production of a polyurethane backing and air frothed foam on a substrate comprising the steps of a) mixing a polyisocyanate and a polyol blend in the presence of a catalyst to form a reaction mixture, b) applying the reaction mixture to a substrate, and c) curing the reaction mixture to form a polyurethane backing an/or an air frothed foam on the substrate. Suitable catalyst compositions for the present invention include those corresponding to the formula: ##STR1## wherein: each R: independently represents a linear or branched C. sub. 1 to C. sub. 24 (preferably from 5 to 16 carbon atoms and most preferably from 8 to 12 carbon atoms) alkyl group, or a cyclic group containing from 4 to 24 carbon atoms (preferably from 5 to 16 carbon atoms and most preferably from 8 to 12 carbon atoms).
