Biocide (In-can preservative) — BIT (1,2-Benzisothiazolin-3-one) CAS 2634-33-5

Description

1. Product Overview
BIT (1,2-Benzisothiazolin-3-one, CAS 2634-33-5) is a high-performance in-can preservative widely used to prevent microbial contamination in water-based industrial formulations. It is primarily applied in coatings, adhesives, emulsions, and polymer systems where long-term stability and product integrity are critical. The key value proposition lies in its broad-spectrum antimicrobial efficacy at low dosage, ensuring extended shelf life and reduced product spoilage. Strategically, BIT is essential in modern manufacturing environments where regulatory compliance, product consistency, and cost-efficient preservation are non-negotiable.
