    摘要： Disclosed herein is a composition comprising a non-dusting copper pyrithione dispersion comprising small solid particles of copper pyrithione dispersed in a liquid dispersant, said solid particles having a particle size within a range of from about 0.1 to about 10 microns and a median particle size of from 0.2 to less than 0.5 microns. The dispersion is suitably employed as an antifouling additive for marine paints without risking worker exposure to copper pyrithione dust. Paints containing the small particle copper pyrithione exhibit improved antifouling performance in cold water, as compared to paint containing larger particle copper pyrithione.

    摘要： The present invention relates, in one aspect, to a process for preparing a storage-stable dispersion of a biocide which comprises the steps of: (a) mixing a plastisol, comprising a resin and a carrier, and a biocide to provide a mixture of said plastisol and said biocide (b) heating said mixture of plastisol and biocide to an elevated temperature of between about 30.degree. C. and about 100.degree. C. to provide a homogeneous, storage stable dispersion, said dispersion containing said biocide in an amount of between about one and about 30 weight percent based upon the weight of said dispersion, said resin being present in an amount of between about 5 and about 75 weight percent based upon the weight of said dispersion, with the proviso that when the weight percent of said resin in said dispersion is between about 30% and about 75%, then said elevated temperature is between 30.degree. C. and 45.degree. C., and when the weight percent of said resin in said dispersion is between about 5% and about 29%, then said elevated temperature is between 46.degree. C. and 100.degree. C., and (c) cooling the dispersion to a temperature of between about -20.degree. C. and about 40.degree. C. to provide a storage-stable mixture having a viscosity of between about 2,000 and about 30,000 centipoise.

    摘要： The present invention relates generally to paints and paint bases, and, more specifically to a process for providing a stable gel-free dispersion of zinc pyrithione plus cuprous oxide biocide in paint. In accordance with the process of the present invention, the zinc pyrithione is purified to a purity assay of at least 98% in order to provide gellation-inhibition in the paint.
