  1. Application field
    Benzisothiazolinone (BIT) is an organic compound with the formula C6H4SN(H)CO. BIT is widely used as a preservative and antimicrobial.

Benzisothiazolinone (BIT) is the main industrial sterilization, antiseptic, and anti-enzyme agent. It has a prominent inhibitory effect on the growth of molds, algae and other microorganisms in organic media, and can solve the mold, fermentation, deterioration, demulsification, odor, etc. of organic products caused by the growth of microorganisms. A series of problems are widely used in sterilization, marine antifouling and other fields.

Benzisothiazolinone (BIT) is widely used as preservative, for example in emulsion paints, caulks, varnishes, adhesives, inks, and photographic processing solutions, home cleaning and car care products; laundry detergents, stain removers and fabric softeners, industrial settings, for example in textile spin-finish solutions, leather processing solutions, preservation of fresh animal hides and skins, agriculture in pesticide formulations, gas and oil drilling in muds and packer fluids preservation.

Benzisothiazolinone BIT-85 is used as one of formula materials; can be made into BIT products with different degrees of concentration;

Benzisothiazolinone BIT-85 is used in the latex, industrial oil additives, leather, paint, textile, printing and dyeing, daily chemicals, and cosmetics industries to protect against corrosion.
