Abstract: A carpet and carpet tile resistant to the growth of Gram negative, Gram positive and fungal organisms which contains a polymeric non-plasticized PVC tuftlock precoat, fusion bonding adhesive, or secondary backing which has incorporated in it a phosphoric acid ester or its salt of the general formula: ##STR1## wherein R and R' are alkyl, oxyalkyl, polyoxyalkyl, aryl, aralkyl or alkaryl groups of C.sub.1 to C.sub.24, and one of R or R' can be H; X is a Group I metal ion, Group II metal ion, transition metal ion, or NY.sub.1 Y.sub.2 Y.sub.3 Y.sub.4, where Y.sub.1-4 are hydrogen, a hydrocarbon of C.sub.1 to C.sub.24, or a hydroxyalkyl group of C.sub.1 to C.sub.24 ; and there is at least one free hydroxyl group; and when X is NY.sub.1 Y.sub.2 Y.sub.3 Y.sub.4 or a Group I metal ion, n is 1, when X is a Group II metal ion, n is 2; and when X is a transition metal, n is equal to the valence of the metal.

Abstract: An biocidal protective coating and an method for coating heat exchanger coils, which includes a polymeric composition comprising an organic water resistant polymer and a compound of the general formula ##STR1## wherein X is selected from the group consisting of organic ions, H.sup.T, Group I metals, Group II metals and transition metals, R and R' are independently selected from the group consisting of hydrocarbons and substituted hydrocarbons of not more than 24 carbon atoms, and there is at least one free hydroxyl group.

Abstract: A reactive polyurethane mixture is applied by a high pressure airless spray applicator directly onto the primary backing of a moving substrate such as a carpet web. The applied reactive mixture is allowed to foam to an approximate predetermined thickness and density. While the blown or foamed backing layer still possesses substantial residual tackiness, it is compressed or regauged to a precise uniform thickness and simultaneously is provided with either an embossed or a smooth surface. The tack of internal cell walls of the blown backing layer retains the layer at the regauged thickness. Curing of the regauged backing layer by externally applied heat and/or by the heat of the exothermic reaction in the applied mixture is completed. Detackifying agents are applied to the regauging devices and/or to the applied backing layer to prevent adherence of the layer to the regauging devices. A surface skin formed of the detackifying agents is cured on the regauged backing layer.
