What is Benzisothiazolinone?
Benzisothiazolinone (CAS 2634-33-5), commonly abbreviated as BIT, is a broad-spectrum biocide used to prevent microbial degradation in industrial formulations and manufactured goods.
Where is Benzisothiazolinone used?
- Paints, coatings and adhesives: in-can preservative against spoilage during storage
- Metalworking fluids and lubricants: control of bacterial growth causing fluid breakdown and corrosion
- Leather, textile and paper: protection during processing and in finished goods
- Water treatment and cooling systems: biostatic agent limiting biofilm in recirculating circuits
- It targets bacteria, fungi and yeast under many pH conditions.
Commercial specifications
- Concentration levels vary by application requirement
- Formulated blends with complementary biocides are available
