Description

Trisodium Phosphate is an inorganic salt widely recognized for its powerful cleaning, degreasing, and water-softening properties. This versatile compound is essential for industrial and institutional applications where effective removal of oils, greases, and soils is required. Key industries that rely on this product include metal treatment, food processing equipment sanitation, and the formulation of industrial and institutional cleaning agents.

Application

• Industrial & Institutional (I&I) Cleaning: A key ingredient in heavy-duty degreasers, metal cleaners, and floor cleaners for warehouses, garages, and food processing plants.
• Metal Surface Treatment: Used in metal finishing processes for cleaning, degreasing, and as a component in phosphate conversion coatings to prepare surfaces for painting.
• Food Processing Sanitation: Employed for cleaning and sanitizing food processing equipment, pipelines, and vessels due to its efficacy against fats and proteins.
• Water Treatment: Acts as a corrosion inhibitor and water softener in boiler water treatment and other industrial water systems to control scale and sludge.
• Detergent & Soap Builder: Functions as a builder in powdered laundry and dishwashing detergents to enhance cleaning power by sequestering water-hardening minerals.
• Paint & Coating Removal: Effective in formulations designed for stripping old paint and coatings from various surfaces.
