Description

2-tert-Butyl-5-Chloro-Isothiazol-3-One is a highly effective isothiazolinone-based biocide and preservative. This compound is valued for its broad-spectrum antimicrobial activity against bacteria, fungi, and algae, making it a critical component for preventing microbial degradation in various industrial and consumer formulations. It is primarily sought by manufacturers in the paints & coatings, adhesives, metalworking fluids, and personal care industries to ensure product stability and shelf-life.

Application

• Primary preservative in water-based paints, coatings, and adhesives to prevent in-can spoilage.
• Microbiocide in metalworking fluids and industrial coolants to control microbial growth and maintain system integrity.
• In-can preservative for household and industrial cleaning products, including detergents and fabric softeners.
• Additive in polymer emulsions and latex to protect against biodeterioration during storage.
• Preservative agent in select personal care formulations such as shampoos and liquid soaps (subject to regional regulatory approval).
• Biocide in construction materials like caulks, sealants, and grouts.
• Wood preservative for timber and composite materials against fungal decay.
• Antimicrobial treatment for textiles and leather during processing and storage.
