It proactively prevents the precipitation and accumulation of calcium carbonate and calcium sulfate deposits on heat transfer surfaces.
Understanding these properties helps in both safety and application:
Nalco 3DT 449 is a high-performance, technologically advanced cooling water treatment chemical. From a safety perspective, it behaves like a typical . It is not highly toxic or explosive, but it poses a significant risk of eye damage and skin irritation in its concentrated form. Proper PPE is the primary control measure required for safe handling.
Do not get in eyes, on skin, or on clothing. Use only with adequate ventilation and wash hands thoroughly after handling. nalco 3dt 449 msds
: Mists or vapors may cause respiratory irritation.

: Prevents the formation of calcium carbonate and calcium sulfate deposits. It is not highly toxic or explosive, but
Category 1 or 2 (depending on the exact concentration matrix, often classified as a severe skin irritant or corrosive).
Dike and contain the spill. Absorb the liquid with an inert material (such as sand, earth, or vermiculite). Scoop up the material and place it in a chemical waste container approved for disposal. Neutralize residue carefully if required by plant protocols, and flush the area with water. 6. Handling and Storage Requirements Avoid direct contact with skin, eyes, and clothing. Do not breathe vapors, mists, or aerosols. Ensure adequate ventilation, especially in confined spaces.
Nalco 3DT449 is formulated as an engineered blend that serves multiple functional purposes within cooling towers and heat exchangers: Use only with adequate ventilation and wash hands
Nalco 3DT449 is an aqueous solution and is inherently non-flammable and non-combustible. However, if subjected to extreme heat from an external fire, the product can boil dry, and its thermal decomposition may release hazardous fumes including oxides of carbon, phosphorus, and nitrogen.
In the event of accidental exposure, immediate action reduces the risk of permanent injury.
Effectively prevents the formation of calcium carbonate, calcium sulfate, and other mineral deposits on heat transfer surfaces.
A standard Nalco cooling water inhibitor exhibits the following typical properties (refer to your exact document batch for certified values): Liquid Color: Clear to amber/dark straw color Odor: Slight organic or characteristic odor
