Industrial Uses

1. Sealants & Adhesives

  • Polymerization Initiator in Adhesives: Ammonium persulphate is used as an initiator in the polymerization of monomers, helping create strong adhesive and sealant products. Its ability to initiate free-radical reactions enhances the production of polymers used in high-performance adhesives.
  • Solvent-Free Adhesive Systems: Ammonium persulphate is often used in solvent-free adhesive formulations where its oxidizing properties help improve curing and bonding strength.

2. Personal Care

  • Hair Bleaching and Dyeing Agent: Ammonium persulfate is often used in hair bleaching and dyeing products. It acts as a bleaching agent that breaks down the natural pigment in hair, allowing for color changes.
  • Oxidizing Agent: In certain formulations, it functions as an oxidizing agent to modify the properties of the formulation, such as stabilizing or activating ingredients.

3. Chemical Synthesis

  • Polymerization Initiator: Ammonium persulfate is widely used as a free-radical initiator in the polymerization of monomers such as acrylonitrile, acrylics, and styrene. This is critical in the production of polymers and resins, including latex.
  • Etching and Cleaning Agent: It is used in printed circuit board (PCB) manufacturing for etching copper and in textile industry for desizing, bleaching, and cleaning.
  • Disinfectant and Oxidizer: It is also employed as an oxidizing agent in various chemical processes, such as wastewater treatment, to eliminate organic contaminants.
  • Soil Remediation: Due to its oxidative properties, ammonium persulfate is utilized in soil remediation processes to break down pollutants.

4. Cleaning & Disinfectants

  • Industrial Cleaning: Ammonium persulphate is used in industrial cleaning applications due to its ability to break down organic contaminants and residues. It is effective in cleaning surfaces, equipment, and machinery, especially in industries like electronics and textiles.
  • Disinfectant Production: While not a disinfectant itself, ammonium persulphate plays a role in the synthesis of disinfectant chemicals due to its oxidizing properties.

5. Lubricants & Automobiles

  • Surface Preparation in Lubricant Applications: Ammonium persulphate can be used for the preparation of metal surfaces in lubricant formulations, ensuring that the surfaces are clean and free from oils and contaminants, improving the adhesion of lubricant additives.
  • Automobile Coatings: In the automotive industry, ammonium persulphate can be used in surface treatments and coatings to enhance durability and prevent corrosion on metal parts.
