ADVANTAGES
  • for temporary protection of products during transport, storage and operation
  • as a base for paint coatings to improve their anti-corrosive and mechanical properties
  • as a coating for facilitating hot plastic forming of metals – broaching, extrusion, pressing
  • as anti-friction layers that reduce coefficient of friction and component wear and tear
  • as insulating layers for electrical engineering applications
