Overview

BIOBAN™ CS-1135 is a high-performance industrial preservative developed by Dow, designed for controlling microbial growth in water-based and semi-aqueous systems. This preservative is based on CMIT/MIT (Chloromethylisothiazolinone / Methylisothiazolinone) blend, a widely trusted active combination that offers excellent broad-spectrum protection against bacteria, fungi, and yeast. BIOBAN™ CS-1135 is highly suitable for paints, coatings, adhesives, polymer emulsions, and construction chemicals, where product integrity and long-term stability are critical. Its high activity at low dosage and compatibility with multiple formulations make it an economical and reliable solution for industrial preservation.
