APPLICATION
• PTBC is a high efficient agent as composite antiscale corrosion inhibitor, it is also the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as antiscale corrosion inhibitor, especially suitable to composite with zinc salt and copolymer. It can be used in situations of high temperature, high hardness, high alkali and high index of condense multiples, it is used as chelating agent and metal detergent in lavation fields.
PACKING
• 25kg or 250kg in plastic barrel.
STORAGE AND TRANSPORTATION
• Store for one year in cool and dry place.
• It is acidic, avoid contacting with eyes and skin, once contacted, flush with water.
