A plywood-patching composition is provided based on a noncellular polyurethane elastomer prepared by reacting a polyether or polyester polyol with a polyisocyanate in the presence of a catalytic amount of a substantially anhydrous potassium salt of a carboxylic acid having from 2 to about 20 carbon atoms, and process for preparing same. The catalysts utilized are relatively non-toxic, yet they promote rapid polymerization with essentially no foaming for a wide variety of non-cellular polyurethane elastomeric applications, particularly in plywood-patch applications where even small amounts of foaming is deleterious to the properties thereof.
