Unlike many traditional biocides that lose efficacy in alkaline conditions, Nalco 73385 maintains its performance even at elevated pH levels. HKCT Malaysia Targeted Microbial Control : It is highly effective at controlling slime-forming sulfate-reducing bacteria (SRB)

NALCO 73385 is a specialized non-oxidizing biocide formulated by Nalco Water, an Ecolab company, primarily designed for industrial water treatment. It is widely used in cooling water systems and closed loops to control microbial growth, particularly slime-forming and sulfate-reducing bacteria. Given its chemical nature, understanding the (Material Safety Data Sheet) or SDS (Safety Data Sheet) is critical for safe handling, environmental compliance, and effective application. nalco 73385 msds
