Claims25
A biocide-composite comprising
- a) at least one biocide and
- b) at least one non-biocidal solid selected from the group consisting of a thermoplastic, an embrittling agent, and combinations thereof.
A biocide-composite obtainable by a process for preparing a biocide-composite comprising the steps of
- a) contacting the at least one biocide with the at least one non-biocide solid,
- b) mixing and melting the at least one biocide with the at least one non-biocide solid to form the biocide-composite
- c) cooling the biocide-composite obtained in step b) to form a solid biocide-composite, and
- d) optionally comminution of the solid biocide-composite to obtain the biocide-composite in particulate form.
