In the world of industrial water treatment, precision and safety are paramount. NALCO 77225 is a specialized chemical formulation used primarily for boiler water treatment, scale inhibition, and corrosion control in high-pressure steam systems. However, a chemical is only as safe as the information that accompanies it. This is why the is a critical document for any facility using this product.
A: Possibly. Always cross‑check Section 7. Some updates add temperature limits or specific incompatibility warnings.
The chemical behavior of NALCO® 77225 dictates its strict storage and safety handling prerequisites. According to Section 9 of the Nalco 77225 GHS SDS , its core physical and chemical benchmarks include: Value / Specification Clear, light-yellow liquid Odour Distinctly ammoniacal pH (100% Concentration) 13.5 (Highly Alkaline) Relative Density 1.46 – 1.50 at 25 °C (77 °F) Solubility in Water Completely soluble Freezing Point -19.9 °C (-4 °F) Flash Point Does not flash (Non-flammable aqueous liquid) Dynamic Viscosity 8 – 16 mPa·s (cps) at 25 °C 3.
