Description

3(2H)-Chloro-2-Methyl-3(2H)-Isothiazolone, Calcium Chloride Complex is a stabilized, solid form of a powerful isothiazolinone biocide, designed for reliable and controlled release of the active antimicrobial agent. This complex offers significant advantages in handling and formulation stability compared to liquid isothiazolinone products, mitigating common challenges like degradation and volatility. It is a critical component for manufacturers in the water treatment, paint, adhesive, and personal care industries who require a robust, long-lasting preservative to prevent microbial spoilage and ensure product integrity.

Application

• Industrial Water Treatment: Used as a non-oxidizing biocide in cooling towers, process water, and paper mill systems to control bacteria, fungi, and algae.
• Paints & Coatings Preservation: An effective in-can preservative for water-based paints, latex emulsions, and polymer dispersions to prevent microbial degradation.
• Adhesives & Sealants: Protects water-based adhesive formulations from spoilage caused by bacteria and fungi during storage.
• Personal Care & Cosmetics: Serves as a preservative in rinse-off products and certain leave-on formulations where a solid, stabilized active is preferred.
• Metalworking Fluids: Incorporated to extend the service life of synthetic and semi-synthetic fluids by controlling microbial growth.
• Household & Institutional Cleaners: Used as a preservative in liquid detergent and cleaner formulations to maintain shelf-life.
• Oilfield Applications: Applied in drilling muds and fracturing fluids to prevent bacterial-induced corrosion and spoilage.
