Product Applications
  • Hard Surface Cleaning: A wide variety of moderately to heavily soiled surfaces are cleaned with TKP-based formulations. Generally the high solution pH and superior grease and oil emulsifying properties are important. Examples of hard surface cleaning applications are: 
  1. Concrete and garage floors
  2. Pre-paint cleaners
  3. Heavy-duty & general purpose institutional cleaners
  4. Auto metal parts
  5. Household products
  6. Scouring cleansers
  • Water Conditioning: TKP is an excellent water softening agent due to its ability to precipitate both calcium and magnesium ions. In some industrial applications softening the water at high pH levels is a distinct advantage.
  • Textile Applications: TKP can be used in scouring and bleaching baths to provide high pH and alkalinity as well as removing potential stain producing cations, such as iron, by precipitation. It can also provide pH and buffer capacity to maintain alkaline dye baths in the proper pH range for maximum effectiveness, thereby prolonging the life of the bath.
  • Refinery Operations: TKP is used for sulfur recovery in sour-gas scrubbing.
  • Industrial Water Treatment: TKP is added to specialty boiler water treatment formulations to aid in corrosion control.
