Abstract: This invention is directed to a broad spectrum fungicide/algaecide composition which comprises a mixture of (a) at least one halopropynyl compound and (b) at least one sulfur-containing s-triazine, said mixture provided in an amount to prevent and/or protect a substrate from attack by one or more fungal and/or algael organisms. The composition can be used broadly in industrial systems and more particularly with substrates such as paints, coatings, stucco, concrete, stone, cementaceous surfaces, wood, caulking, sealants, textiles, and the like.

Abstract: A synergistic composition of biocides for the preparation of anti-fouling paint preferably containing at least one of the group of 3-iodo-2-propynyl-butyl carbamate, 3-iodo-2-propynyl-cyclohexyl carbamate, 3-iodo-2-propynyl phenyl carbamate, 3-iodo-2-propynylbenzyl carbamate, 3-iodo-2-propynyl propyl carbamate and 4-iodo-3-butynyl propyl carbamate and at least one of the group of tributyltin compounds consisting of bis(tributyltin) oxide, tributyltin fluoride, tributyltin methacrylate, tributyltin phosphate and tributyltin naphthenate. Said composition is more effective in protecting ship bottoms or underwater constructions than each component itself.

Abstract: A composition for preserving wood or composite wood materials and for treating soil containing a compound selected from the group consisting of 3-iodo-2-propynyl-butyl carbamate, 3-iodo-2-propynyl hexyl carbamate, 3-iodo-2-propynyl cyclohexyl carbamate, 3-iodo-2-propynyl phenyl carbamate, and mixtures thereof, and at least one pyrethroid-type insecticide selected from the group consisting of cyano-(4-fluoro-3-phenoxyphenyl)-methyl-3-(2,2-dichloroethyl)-2,2-dimethyl -cyc lopropanecarboxylate, 3-phenoxyphenyl)-methyl-3-( 2,2-dichloroethenyl)-2,2-dimethyl-cyclo-propanecarboxylate, cyano-(3-phenoxyphenyl)-methyl-3-(2,2-dichloroethenyl)-2,2-dimethyl-cyclop rop anecarboxylate, cyano-(3-phenoxyphenyl)-methyl-2-(4-chlorophenyl)-3-methylbutyrate, and mixtures thereof.

Abstract: The invention comprises a method for the color stabilization of iodoalkyne carbamates by the addition thereto of selected epoxy compounds. The epoxy compounds which thus function as stabilizers may be employed as a part of solutions containing the iodoalkyl carbamates, or they may be employed as a part of the films, coatings or compositions containing the iodoalkyne compounding.

Abstract: Adducts of formaldehyde and selected amines (primary and secondary) and their use as enzyme inhibitors in aqueous systems containing cellulosic substances and compositions containing same; and particularly aqueous paint compositions containing said adducts as enzyme inhibitors to retard hydrolytic splitting of cellulose linkages.
