  • DERUSTING- It is a hydrochloric acid based chemical for dip derusting and descaling of iron and steel surfaces.
  • ACTIVATION- It is basically Titanium Complex in mild alkaline medium in powder form and used by dip or spray to prepare a solution for conditioning metal surfaces when denser, uniform and finely crystalline phosphate coatings are desired.
  • PHOSPHATING- It is a nitrate-nitrite accelerated zinc phosphating chemical used by immersion process at ambient temperature. It produces a smooth, compact, uniform coating on steel and zinc surfaces.
