Technical Information: Preservation of Polymer Dispersions

Water-based polymer dispersions are prone to contamination by microorganisms, necessitating the use of biocides for preservation. The selection of suitable biocides depends on factors such as regulations, application considerations, stability, and efficacy. Compliance with local regulations is crucial. In the EU, the Biocidal Products Regulation (BPR) governs biocide use. Chemical compatibility and stability throughout the shelf life are essential. Regular monitoring of batches and microbial challenge tests are necessary. Biocidal treatment alone is insufficient; strict hygiene measures in production, packaging, transportation, and storage are vital. This brochure provides a concise overview of preservation and maintaining microbiological quality.
