Nalco 77225 Safety Data Sheet Upd [better] -

Nalco 77225 is an advanced liquid chemical treatment primarily used for internal boiler water systems. It is specifically designed to control scale formation and optimize boiler efficiency by utilizing a proprietary blend of complex phosphates and "Transport Plus" polymer technology.

Because Nalco 77225 is a highly alkaline product with a pH greater than 13, maintaining an updated Safety Data Sheet (SDS) is critical for workplace safety and regulatory compliance. Key Product Features and Applications

Nalco 77225 is engineered for boilers operating at pressures up to 40 barg. Its primary functions include:

Scale Control: The complex phosphate reacts with calcium and magnesium, while the organic polymers transport these minerals (along with iron and silica) through the boiler to prevent adherent deposits.

Corrosion Mitigation: By stabilizing hardness and preventing fouling, it protects the structural integrity of the boiler system.

Improved Efficiency: Reducing tube overheating and scale buildup leads to longer production runs and less downtime for cleaning. Safety and Hazard Overview

Nalco 77225 is classified as a hazardous, highly alkaline chemical (pH >13) capable of causing severe skin burns, eye damage, and metal corrosion. It is harmful if swallowed and poses risks to aquatic life. Critical Handling and First Aid Measures

Due to its high alkalinity, immediate action is necessary upon contact:

Eyes/Skin: Rinse immediately with water for 15+ minutes and seek urgent medical attention.

Ingestion/Inhalation: Do not induce vomiting; move to fresh air and consult a physician. Nalco 77225 SDS (GHS) | PDF | Toxicity - Scribd
