Safe for ferrous metals (cast iron), copper, copper alloys, and aluminium. It is also designed to be non-harmful to rubber gaskets, O-rings, and seals . msds nalco 2000
Always top up with a mixture of one part Nalco 2000 for every 32 parts of de-mineralized water .
Not typically required under normal operating conditions. If mists or vapors are generated and engineering controls are insufficient, use an approved respirator equipped with organic vapor/acid gas cartridges and a particulate pre-filter. 7. Physical and Chemical Properties
The —now commonly referred to as the SDS (Safety Data Sheet) under the Globally Harmonized System (GHS)—for Nalco 2000 (commercially known as NALCOOL® 2000 or NALFLEET™ 2000 ) classifies this product as a mildly alkaline liquid that poses specific health and environmental hazards, primarily functioning as a specialized corrosion inhibitor and scale suppressant for diesel engine closed cooling systems. Produced by Nalco Water, an Ecolab company, this industrial chemical relies heavily on a sodium nitrite base, which carries a critical warning regarding skin irritation, serious eye irritation, and severe toxicity if swallowed. | | CAS Number | Concentration (% w/w)
Immediately flush eyes with water for at least 15 minutes while holding the eyelids open. Get prompt medical attention.
The Safety Data Sheet (SDS), formerly known as a Material Safety Data Sheet (MSDS), provides critical information for the safe handling, storage, and application of this specialized engine cooling treatment. Manufactured by companies like Nalco Water (an Ecolab company) and Wilhelmsen , NALCOOL 2000 is a nitrite-based corrosion inhibitor designed specifically for closed cooling systems, particularly in diesel engines. 1. Product Identification and Core Hazards
The efficacy of Nalco 2000 relies on a specialized blend of inhibitors, which typically includes: for the inhibitor's effectiveness
By thoroughly reviewing Sections 2 (Hazards), 4 (First Aid), 6 (Spill Response), and 8 (PPE) of the current MSDS, and by integrating that knowledge into daily operations, water treatment professionals can harness the benefits of Nalco 2000 while protecting their workforce and the environment. Always remember:
According to standard product data sheets, Nalco 2000 is highly recognizable by its physical profile: SAFETY DATA SHEET NALCOOL® 2000
Chemical-resistant gloves (e.g., Nitrile) and protective clothing. 3. Usage and Application Guidelines
Chemical-resistant gloves (such as neoprene, nitrile, or PVC) and protective clothing (aprons or lab coats) to prevent skin contact.
Immediately flush eyes with gently flowing water for at least 15 minutes, holding the eyelids open. Remove contact lenses if present and easy to do. Seek immediate medical attention.
