<p>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 °C and about 100 °C to provide a homogeneous, storage stable dispersion, and (c) cooling the dispersion to a temperature of between about -20 °C and about -40 °C to provide a storage-stable mixture having a viscosity of between about 2,000 and about 30,000 centipoise.</p> |
