Abstract: Compositions of matter which include 1, 2-benzisothiazolin-3-one (also known as “BIT”) and a divalent metal carboxylate and exhibit desirable activity for inhibiting microbial growth are described. Methods for preserving an aqueous solution or dispersion from degradation by bacteria or fungus, and methods for preserving a dry film from degradation by bacteria or fungus, are also described. The inventive mixtures provide greater antimicrobial protection per unit mass of metal carboxylate and BIT against certain microbes than is exhibited per unit mass by the metal carboxylate alone or by BIT alone. Desirable antimicrobial activity has been observed with mixtures of the invention against Pseudomonas aeruginosa, Escherichia coli, Enterobacter aerogenes, and Alcaligenes faecalis, among others.

Abstract: A broad spectrum antimicrobial composition consisting essentially of an iodopropynyl compound in combination with a benzimidazole and a metal borate is disclosed. The composition can be used to protect industrial systems against microbial growth and, more particularly, to protect substrates such as paints, coatings, stucco, concrete, stone, cementaceous surfaces, wood, wood-plastic composites, caulking, sealants, textiles, leather, wood, preservatives, metal working fluids, drilling muds, clay slurries, glazes, optical brighteners, carpet backing, and pigments against microbial growth. The composition can be used as a preservative for aqueous products.

Abstract: A combination product including a mixture of 3-iodpropynyl-N-n-butylcarbamate (“IPBC”) and 2-n-N-butyl-1,2-benzisothiazolin-3-one (“BBIT) for use as a fungicide and growth inhibitor in industrial applications. Combination products of the present invention are effective for inhibiting the growth of microorganisms, and exhibit a synergistic antifungal effect against fungi such as, for example, Aspergillus niger, Penicillium funiculosum, Trichoderma virens, Chaetosphaeridium globosum, Penicillium sp., and Caratocystis Pilifera. Methods for using the product in metal working fluids, dry film coatings, in-can preservatives, caulks, sealants leather, wood, rope, cordage, textiles, ink, adhesives and polymeric materials are also described.

Abstract: Non-yellowing degassing compositions which enhance degassing in powder coatings and other film-forming curable coatings are disclosed. The non-yellowing compositions contain degassing agents including a plurality of unfused aromatic rings and at least one functional group selected from ketals, carbamates, carbonates and carboxylic acid esters. The degassing agents resist decomposition and discoloration, and are relatively stable at resin curing conditions. The degassing agents may be synergistically combined with other materials, such as fatty acid amide-containing waxes, to produce new and surprisingly effective degassing compositions suitable for use in powder coatings. Curable compositions which utilize the new degassing compositions are also disclosed.

Abstract: The invention provides co-solvents for preparing clear solutions of a biocidal agent known as 10, 10?-oxybisphenoxarsine (OBPA). The clear solutions are stable over a relatively broad range of temperatures and have very low Volatile Organic Carbon (VOC) content. They can be included in master batches for the manufacture of plastic materials, such as flexible PVC. The co-solvents of this invention have very low VOC values, do not have troublesome odors, do not cause significant irritation during the high temperature plastic manufacturing process, and are miscible in a range of useful concentrations with plasticizers presently employed by plastics manufacturers. The use of castor oil and/or modified castor oils such as glyceryl ricinoleate, dehydrated castor oil, and certain alkoxylated castor oils as a co-solvent to increase the dissolvable concentration of OBPA, alone or in solution with a plasticizer, was not known or expected.
