Abstract: A preservative composition comprising an isothiazolinone, such as 1,2-benzisothiazolin-3-one, and a polyethertriamine in a synergistic combination. The polyethertriamine enhances the antimicrobial activity of the isothiazolinone, achieving the desired antimicrobial activity at synergistically lower concentrations than with the isothiazolinone in the absence of the polyethertriamine. Also, methods of using the preservative compositions to provide wet-state preservation of industrial materials including paints, coatings, and metal working fluids.
Abstract: An aqueous dispersion containing BIT and IPBC prepared using nonionic and anionic surfactants exhibits both chemical and physical stability and is suitable for use as a single product which is capable of imparting to a coating composition a high level of resistance against attack by a broad spectrum of organisms, including bacteria, fungi and algae, in both the wet-state and dry film-state.
