Description

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

Application

• Industrial & Institutional Cleaning: A primary ingredient in heavy-duty degreasers, metal cleaners, and concrete floor cleaners for factories, warehouses, and food processing plants.
• Metal Surface Treatment: Used in phosphatizing and cleaning solutions to prepare steel, aluminum, and other metal surfaces for painting, coating, or plating by removing rust, scale, and grease.
• Food Processing Sanitation: Employed as a cleaning and sanitizing agent for food processing equipment, pipelines, and dairy facilities due to its efficacy against fats and proteins.
• Water Treatment & Softening: Acts as a precipitating agent and corrosion inhibitor in boiler water treatment and industrial water systems to control scale and hardness.
• Detergent & Formulation Builder: Serves as a builder in powdered and liquid detergent formulations, enhancing cleaning power by sequestering metal ions and emulsifying soils.
• Paint Stripping & Removal: An effective component in paint stripping formulations for removing old paint layers from various surfaces.

Quality Control

Our Trisodium Phosphate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. We offer various grades, including technical and food-grade (FCC), with specifications tailored to meet the demands of your specific application. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters such as assay, heavy metal content, and loss on drying.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and absorption of atmospheric moisture. Store away from strong acids.
