  • Preventing Corrosion: It prevents corrosive residues from affecting soldered joints.

Ammonium Chloride in Galvanizing

Enhancing Corrosion Resistance

Ammonium chloride plays a pivotal role in the galvanizing process:

  • Galvanized Coatings: In hot-dip galvanizing, it serves as an electrolyte, creating a protective zinc coating on steel, enhancing corrosion resistance.
  • Oxide Coating Removal: It eliminates oxide coatings on metal surfaces before galvanizing.

Beyond Metals: Rocket Fuel and More

Expanding Applications

Ammonium chloride’s versatility extends to rocket fuel, where it acts as an oxidizer, enabling high-temperature gas release for propulsion. It is also used as a starting reagent for some types of rocket fuel.
