will recognize that the basic polyurethane formulation provides a dense tough elastomeric material the small amount of catalyst indicates that the formulation will require a long time to cure without the application of additional energy further it has been found that the diamine further retards the curing of the polyurethane material so that external heat is a virtual necessity to the curing of the material in the context of the systems discussed in conjunction with the drawings the lack of catalyzed curing is advantageous this fact allows the secondary coating to be applied and manipulated as described only after all preliminary steps have been completed is the substrate with the coatings passed through a curing oven thus the application and curing of the backings can be carefully controlled for the desired end product the product of the present invention can be a carpet having a precoat to lock in the yarns and having a secondary coat that provides a nonskid characteristic the carpet can therefore be used as a car mat wherein the mat must remain in place under the driver 39 s feet or can be used as an entry mat wherein the mat must remain in place through heavy traffic other uses will suggest themselves to those skilled in the art the method of the present invention provides means for producing a carpet or the like wherein two separate coatings can be applied to a substrate though it should be realized that the nonskid coating can be applied to a secondary backing the precoat will normally be a smooth coating and the nonskid coatings will normally be in stripes areas or other.
