Trisodium phosphate (TSP) is widely used in various technical and industrial applications due to its strong alkaline properties, emulsifying ability, and cleaning efficiency. Here are some key applications:

1. Cleaning & Degreasing

• Used as an industrial degreaser for removing grease, oil, and stains from metal, concrete, and painted surfaces.

• Common in household and commercial cleaning products.

2. Water Treatment

• Acts as a scale inhibitor and water softener in boiler water treatment systems.

• Helps in preventing corrosion and controlling pH in water treatment plants.

3. Metal Surface Preparation

• Used in metal cleaning and preparation before painting or coating to remove rust, oils, and oxides.

• A key ingredient in phosphating solutions to enhance paint adhesion.

4. Textile Industry

• Employed as a buffering agent in dyeing and bleaching processes.

• Helps in stain removal and fabric processing.

5. Paper & Pulp Industry

• Used in paper processing to control pH and improve pulp bleaching.

• Assists in removing ink during paper recycling.

6. Food Processing (Limited Technical Use)

• Though used as a food additive (E339), industrial-grade TSP is applied in cleaning and sanitization of food processing equipment.

7. Construction Industry

• Used in cement formulations as a setting regulator.

• Helps in cleaning and etching surfaces before painting.

8. Automotive & Aerospace

• Used in degreasing engine parts and cleaning aircraft components.

• Helps in removing residues from manufacturing processes.
