• Expiry Date:

  Apr 29,2017

• Detailed Description:

  Cas No. :37971-36-1

  Introduction s:

  PBTC has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

  Usage:

  PBTC is a high efficient agent as scale and corrosion inhibitor. PBTC is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield re injection water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. PBTC can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent.

  PBTC is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.

  Safety Protection:

  Acidity, a void contact with eye and skin, once contacted, flush with water.

  Package and Storage:

  200L plastic drum, IBC(1000L),customers’ requirement. Storage for one year in shady room and dry place.
