Nalco 77352 Msds -
It is typically fed into a cooling tower basin or recirculating line via a chemical metering pump. The product is often used in conjunction with oxidizing biocides (like chlorine or bromine).
The Material Safety Data Sheet (MSDS) describes a liquid biocide used primarily for controlling microorganisms in industrial water systems, such as cooling towers and brewery pasteurizers. Key Hazard Profile
is a specialized biocidal product manufactured by Ecolab (Nalco), frequently utilized in industrial water treatment applications to control microbial growth. For safety professionals, facility managers, and operators, understanding the NALCO 77352 Safety Data Sheet (SDS) —formerly known as the Material Safety Data Sheet (MSDS)—is critical for compliant handling, storage, and emergency response.
Isothiazolin-3-one biocidal agents (such as 2-Methyl-3(2H)-isothiazolone) blended with Magnesium Nitrate stabilizing carriers.
No specific OELs established for the mixture. However, for phosphonates and acrylic polymers, general nuisance dust or mist limits apply (e.g., ACGIH TLV of 10 mg/m³ for inhalable particles).
To maintain a safe working environment, facilities must implement engineering controls and mandate specific PPE. nalco 77352 msds
