Abstract
This invention relates to a process improvement for preparing a storage-stable dispersion of a biocide which comprises the steps of: (a) dispersing a solid biocide and a carrier to form a biocide concentrate, (b) heating said biocide concentrate to an elevated temperature to provide a storage stable mixture of biocide, resin and carrier, and (c) cooling said mixture under continuous stirring to provide a homogeneous, storage-stable liquid dispersion. Also claimed is the storage-stable product produced by this process.
