Chemipol Biopol DHN Biocide

Chemipol Biopol DHN Biocide is a broad-spectrum, non-oxidizing biocide from the Chemipol Biopol series, designed for industrial water systems. It effectively controls bacteria, fungi, and algae without corrosive byproducts. Featuring DHN (2,2-dibromo-3-nitrilopropionamide) as its active ingredient, it offers rapid kill, thermal stability, and compatibility with common water treatment chemistries. Ideal for cooling towers, paper mills, and oilfield applications.
