Benzisothiazolinone (BIT) is a widely used biocide and belongs to the group of isothiazolinones.

Usage

Benzisothiazolinone has a microbicide and a fungicide mode of action. It is used as a preservative in emulsion paints, varnishes, adhesives, washing agents, fuels and in the papermaking process. In paints, it is commonly used as a mixture with methylisothiazolinone. Typical concentrations in products are 200–400 ppm depending on the application area and the combination with other biocides. According to a study in Switzerland, 19% of the paints, varnishes and coatings contained BIT in 2000. The fraction in adhesives, sealants, plasters and fillers was 25%.
