Local:
Sulfamic acid, amidosulfonic acid H3NSO3, is a nonvolatile, white crystals; decomposes at melting point 205 C; slightly soluble in water and organic solvents. The main application can find in metals and ceramics cleaning industry as a replacement for hydrochloric acid to remove rust. It is also used in:

  • Formulating cleaning agents
  • Cleaning metals and ceramics
  • Rust removal agent in air conditioner and cooling system
  • Chemical catalyst for esterification process
  • Dye and pigment manufacturing
  • Ingredient in fire extinguishing media
  • Pulp and paper industry as a chloride stabilizer
  • Plasticizer
  • Chemical intermediate
  • Textile and paper bleaching
  • Herbicide
  • Coagulator for urea-formaldehyde resins

Numerous sulfamates (mono, di, tri O-substituted and N-substituted salts and esters) can be existed for characteristic applications.
