  • Penetrating protectant
    Patent number: 6335374
    Abstract: A penetrating concentrate containing a biocidal amount of a biocide uses a penetrating carrier vehicle containing an emulsifiable copolymer of a cyclic diene and a polymerizable, unsaturated glyceride. For biocides, such as iodopropargyl carbamate, which otherwise requires use of significant amounts of co-solvent to disperse, is directly soluble in the copolymer thereby eliminating or at least substantially reducing the need for co-solvents to assure stability of the biocide in the formulation. The concentrate also exhibits a low level of volatile organics.
    Type: Grant

  • Method of stabilizing biocidal compositions of haloalkynyl compounds
    Patent number: 6124350
    Abstract: This invention is directed to a method for stabilizing a composition which comprises a mixture of a halopropargyl compound. 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.

  • Biocidal compositions comprising mixtures of haloproynyl compounds and sulfur containing triazines
    Patent number: 5948730
    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.
