Hydrofluorosilicic Acid 23% (HFS)
Hydrofluorosilicic Acid (HFS) 23% is a high-performance industrial fluorosilicic acid solution used extensively in municipal water fluoridation and specialized industrial processes. This technical-grade acid provides reliable concentration stability and consistent performance characteristics for demanding industrial applications.
Highly corrosive material requiring stringent safety protocols. Mandatory personal protective equipment includes chemical-resistant suit, fluoroelastomer (FKM) or neoprene gloves, full face shield with chemical splash goggles, and appropriate respiratory protection. Store only in fluorinated or approved high-density polyethylene containers - never use glass or standard metal containers. Facilities must maintain dedicated acid handling areas with proper ventilation systems, containment measures, and emergency safety equipment. Neutralization systems must be readily available. Transportation requires compliance with DOT hazardous materials regulations for corrosive substances.
Our 23% Hydrofluorosilicic Acid solution delivers superior stability and precise concentration control. Each batch undergoes rigorous quality testing to verify acid strength, metal content, and specific gravity specifications. The product maintains optimal performance characteristics for water treatment applications while ensuring consistent results in industrial processes. The standardized specific gravity of 1.12 facilitates accurate metering and dosing operations. Regular quality monitoring ensures product integrity throughout the specified shelf life.
