Overview

BIOBAN™ BP-40 is a premium industrial preservative developed by Dow, formulated to provide fast and effective microbial control in water-based formulations. Its active ingredient, 2-Bromo-2-Nitropropane-1,3-Diol (Bronopol), delivers excellent bactericidal activity and broad-spectrum protection against fungi and yeast. BIOBAN™ BP-40 is ideal for preserving paints, coatings, adhesives, polymer emulsions, and construction chemicals, ensuring product integrity during storage and application. With outstanding solubility and performance at low dosages, BIOBAN™ BP-40 is widely used where rapid microbial kill and long-lasting preservation are critical for maintaining quality and compliance.
