Function:
It has excellent antiseptic properties. In many products, it can prevent the growth of microorganisms and extend the shelf life of the product. Its antiseptic effect is based on the inhibition of microbial growth. By controlling the number of microorganisms, it avoids product deterioration due to microbial metabolic activities.
1,2-Benzisothiazol-3 (2H)-one is a highly effective antimicrobial agent. It can inhibit the growth and reproduction of a variety of bacteria, fungi and algae. Its antimicrobial mechanism is mainly achieved by interfering with the physiological processes within microbial cells.
Application:
Coatings and paints: Added to coatings and paints, it plays an anti-corrosion and anti-mildew role. In architectural coatings, it can prevent the coating from being eroded by mold in a humid environment and maintain the appearance and performance of the coating.
Industrial circulating water and swimming pool water (potential): It has potential application value for the treatment of industrial circulating water and swimming pool water. It can inhibit the growth of algae and bacteria in the water and reduce the formation of scale and biofouling.
Leather antiseptic and mildew proof (potential): In the leather industry, it can be used for leather antiseptic and mildew proof treatment. During the leather tanning and storage process, 1,2-benzisothiazole-3 (2H)-one can prevent microbial damage to leather and maintain the quality of leather.
