5.Usage:
   PBTCA is  widely  used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, It is the excellent stabilizer for zinc salt. It 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.
PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatmen hemicals. When used alone, the dosage of 5-15mg/L  is preferred.
6.Package and Usage:
   Packed in200KG galvanized barrels or 1000KG IBC if possible and stored in a cool ,ventilated and dry place.
